Chemistry happens in the world around you, not just in a lab. Matter interacts to form new products through a process called a chemical reaction or chemical change. Every time you cook or clean, it's chemistry in action. Your body lives and grows thanks to chemical reactions. There are reactions when you take medications, light a match, and take a breath. Here's a look at 10 chemical reactions in everyday life. It's only a small sampling since you see and experience hundreds of thousands of reactions each day.
1.Photosynthesis Is a Reaction To Make Food
Plants apply a chemical reaction called photosynthesis to convert carbon dioxide and water into food (glucose) and oxygen. It's one of the most common everyday chemical reactions and also one of the most important since this is how plants produce food for themselves and animals and convert carbon dioxide into oxygen.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
2.Aerobic Cellular Respiration Is a Reaction With Oxygen

Aerobic cellular respiration is the opposite process of photosynthesis in that energy molecules are combined with the oxygen we breathe to release energy needed by our cells plus carbon dioxide and water. Energy used by cells is chemical energy in the form of ATP.
Here is the overall equation for aerobic cellular respiration:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (36 ATPs)
3.Anaerobic Respiration - Everyday Chemical Reactions

In contrast to aerobic respiration, anaerobic respiration describes a set of chemical reactions that allow cells to gain energy from complex molecules without oxygen. Your muscles cells perform anaerobic respiration whenever you exhaust the oxygen being delivered to them, such as during intense or prolonged exercise. Anaerobic respiration by yeast and bacteria is harnessed for fermentation, to produce ethanol, carbon dioxide, and other chemicals that make cheese, wine, beer, yogurt, bread, and many other common products.
The overall chemical equation for one form of anaerobic respiration is:
C6H12O6 → 2C2H5OH + 2CO2 + energy
4.Combustion Is a Type of Chemical Reaction

Every time you strike a match, burn a candle, build a fire, or light a grill, you see the combustion reaction. Combustion combines energetic molecules with oxygen to produce carbon dioxide and water.
For example, the combustion reaction of propane, found in gas grills and some fireplaces, is:
C3H8 + 5O2 → 4H2O + 3CO2 + energy
5.Rust Is a Common Chemical Reaction

Over time, iron develops a red, flaky coating called rust. This is an example of an oxidation reaction. Other everyday examples include formation of verdigris on copper and tarnishing of silver.
Here is the chemical equation for the rusting of iron:
Fe + O2 + H2O → Fe2O3. XH2O
6.Mixing Chemicals Causes Chemical Reactions

If you combine vinegar and baking soda for a chemical volcano or milk with baking powder in a recipe you experience a double displacement or metathesis reaction (plus some others). The ingredients recombine to produce carbon dioxide gas and water. The carbon dioxide forms bubbles in the volcano and helps baked goods rise.
These reactions seem simple in practice but often consist of multiple steps. Here is the overall chemical equation for the reaction between baking soda and vinegar:
HC2H3O2(aq) + NaHCO3(aq) → NaC2H3O2(aq) + H2O() + CO2(g)
7.Batteries Are Examples of Electrochemistry

Batteries use electrochemical or redox reactions to convert chemical energy into electrical energy. Spontaneous redox reactions occur in galvanic cells, while nonspontaneous chemical reactions take place in electrolytic cells.
8.Digestion- Everyday Chemical Reactions

Thousands of chemical reactions take place during digestion. As soon as you put food in your mouth, an enzyme in your saliva called amylase starts to break down sugars and other carbohydrates into simpler forms your body can absorb. Hydrochloric acid in your stomach reacts with food to break it down, while enzymes cleave proteins and fats so they can be absorbed into your bloodstream through the walls of the intestines.
9.Acid-Base Reactions- Everyday Chemical Reaction
Whenever you combine an acid (e.g., vinegar, lemon juice, sulfuric acid, muriatic acid) with a base (e.g., baking soda, soap, ammonia, acetone), you are performing an acid-base reaction. These reactions neutralize the acid and base to yield salt and water.
Sodium chloride is not the only salt that may be formed. For example, here is the chemical equation for an acid-base reaction that produces potassium chloride, a common table salt substitute:
HCl + KOH → KCl + H2O
10.Soaps and Detergents - Everyday Chemical Reactions
Soaps and detergents clean by way of chemical reactions. Soap emulsifies grime, which means oily stains bind to the soap so they can be lifted away with water. Detergents act as surfactants, lowering the surface tension of water so it can interact with oils, isolate them, and rinse them away.

Based on your topic "chemical reaction", is the chemical reaction in soap making equal to shampon making? Explain please ..
BalasHapusSoaps are sodium or potassium salts of long chain fatty acids. When triglycerides in fat/oil react with aqueous NaOH or KOH, they are converted into soap and glycerol. This is called alkaline hydrolysis of esters. Since this reaction leads to the formation of soap, it is called the Saponification process.
HapusShampoo
. A variety of other compounds are included in shampoos if desired. Dyes for changing color, fragrances for changing the odor, pH adjustment ingredients, chelating agents, opacifying ingredients, and more. Frequently, story ingredients are included so marketers will have something to talk about. This includes things like vitamins, proteins, and herbal extracts which are not normally expected to have any impact on the final product performance. Dandruff shampoos will include a drug active ingredient like zinc pyrithione.
Why iron can be rusted?
BalasHapusBut what exactly is rust? Rust is usually used to refer to a very common, reddish-brown compound called iron oxide (Fe2O3). Iron oxide is formed when iron and oxygen react in the presence of water or moisture in the air.
HapusIron oxide is very common, because iron reacts easily with oxygen in the air. In fact, it reacts so readily with oxygen that it's actually very rare to find pure iron in nature.
Rust can also refer to the reaction of iron and chloride in an underwater environment. This can sometimes be seen on rebar used in underwater pillars. Over time, green rust will appear on these pillars as the iron reacts with chloride in the water.
Can you explain the other example of chemistry in our life?
BalasHapuswhy onion makes you cry? ,Why ice Floats? How soap Cleans? and many more....
HapusTell me more about reaction in human body..!
BalasHapusOxygen (65%) and hydrogen (10%) are predominantly found in water, which makes up about 60 percent of the body by weight. It's practically impossible to imagine life without water.
HapusCarbon (18%) is synonymous with life. Its central role is due to the fact that it has four bonding sites that allow for the building of long, complex chains of molecules. Moreover, carbon bonds can be formed and broken with a modest amount of energy, allowing for the dynamic organic chemistry that goes on in our cells.
Nitrogen (3%) is found in many organic molecules, including the amino acids that make up proteins, and the nucleic acids that make up DNA.
Calcium (1.5%) is the most common mineral in the human body — nearly all of it found in bones and teeth. Ironically, calcium's most important role is in bodily functions, such as muscle contraction and protein regulation. In fact, the body will actually pull calcium from bones (causing problems like osteoporosis) if there's not enough of the element in a person's diet.
Phosphorus (1%) is found predominantly in bone but also in the molecule ATP, which provides energy in cells for driving chemical reactions.
Potassium (0.25%) is an important electrolyte (meaning it carries a charge in solution). It helps regulate the heartbeat and is vital for electrical signaling in nerves.
Sulfur (0.25%) is found in two amino acids that are important for giving proteins their shape.
Sodium (0.15%) is another electrolyte that is vital for electrical signaling in nerves. It also regulates the amount of water in the body.
Chlorine (0.15%) is usually found in the body as a negative ion, called chloride. This electrolyte is important for maintaining a normal balance of fluids.
Magnesium (0.05%) plays an important role in the structure of the skeleton and muscles. It also is necessary in more than 300 essential metabolic reactions.
Iron (0.006%) is a key element in the metabolism of almost all living organisms. It is also found in hemoglobin, which is the oxygen carrier in red blood cells. Half of women don't get enough iron in their diet.
Fluorine (0.0037%) is found in teeth and bones. Outside of preventing tooth decay, it does not appear to have any importance to bodily health.
Zinc (0.0032%) is an essential trace element for all forms of life. Several proteins contain structures called "zinc fingers" help to regulate genes. Zinc deficiency has been known to lead to dwarfism in developing countries.
Copper (0.0001%) is important as an electron donor in various biological reactions. Without enough copper, iron won't work properly in the body.
Iodine (0.000016%) is required for making of thyroid hormones, which regulate metabolic rate and other cellular functions. Iodine deficiency, which can lead to goiter and brain damage, is an important health problem throughout much of the world.
Selenium (0.000019%) is essential for certain enzymes, including several anti-oxidants. Unlike animals, plants do not appear to require selenium for survival, but they do absorb it, so there are several cases of selenium poisoning from eating plants grown in selenium-rich soils.
Chromium (0.0000024%) helps regulate sugar levels by interacting with insulin, but the exact mechanism is still not completely understood.
Manganese (0.000017%) is essential for certain enzymes, in particular those that protect mitochondria — the place where usable energy is generated inside cells — from dangerous oxidants.
Molybdenum (0.000013%) is essential to virtually all life forms. In humans, it is important for transforming sulfur into a usable form. In nitrogen-fixing bacteria, it is important for transforming nitrogen into a usable form.
Cobalt (0.0000021%) is contained in vitamin B12, which is important in protein formation and DNA regulation.

BalasHapusAccording to you, How to keep the iron does not rust
BalasHapusRust has the potential to form on anything that is made out of iron, meaning any piece of farm equipment, automobile, house, railroad, ship, bridge, or any other personal item may suffer from its damaging effects. To protect your belongings, you should consider the following rust prevention techniques that have helped many people keep their tools, cars, and other rust-prone possessions in good condition:
Hapusa) Car Rust Prevention:
The corrosion that takes place on your vehicle can be prevented through frequent cleaning and waxing. Spraying the undercarriage is also a must in order to keep it free of dirt and debris that is often responsible for the collection of moisture [4]. Once a car is washed, sitting it in the sun for a few hours is one of the best techniques of drying to follow. During the winter season, it is important to note that the rise in salty conditions produce a high amount of sodium chloride, which is known to speed up the rusting process [1].
Sometimes, factories will soak the body of a car in chemicals (usually electrically charged) to create layers of rust protection [5]. Some places galvanize (add a coating of zinc) car bodies, which is done before the primer coat of paint is added to the vehicle. Cars possessing a body-on-frame construction may undergo rustproofing techniques to the frame and its methods of attachment. There are also aftermarket kits sold as sprays to add further protection to cars after a new purchase.
b) Blueing:
To prevent rusting of small steel items, such as firepower, bluing is a technique that offers limited protection. Successful application includes the use of water-displacing oil rubbed onto blued steel.
c) Metal Coating:
The control of corrosion may take place when metal is isolated from the rest of its environment, such as paint. In large structures, the process may include the use of a wax-based product (sometimes called a slushing oil), which is injected into sections of objects that poses concern. The oil often contains rust inhibiting chemicals that works to form a protective barrier.
d) Rust Prevention Products:
Investing in highly recommended rust prevention products is a good way to protect the integrity of your car and other metal-containing possessions. Some items come in an aerosol can, while others are applied as gels and liquids. Application wipes are also a common product to consider. A few suggestions to keep in mind include the Boeshield T-9 12 oz. Aerosol Can; Bull Frog Heavy Duty Rust Blocker Gel; and the Sentry Solutions TUF-CLOTH (and the MARINE TUF-CLOTH option).
What is the function amonia?
BalasHapusFertilizer
HapusGlobally, approximately 88% (as of 2014) of ammonia is used as fertilizers either as its salts, solutions or anhydrously.[11] When applied to soil, it helps provide increased yields of crops such as maize and wheat. 30% of agricultural nitrogen applied in the USA is in the form of anhydrous ammonia and worldwide 110 million tonnes are applied each year
Wheter the aerobic reaction always requires oxygen for respiration?
BalasHapusOther cells and organisms will ferment pyruvate into lactate, also known as lactic acid. I’m sure you’ve all been told that your muscles hurt during and after exercise because you have an excess build of lactic acid in your muscles. This is because of anaerobic respiration. During exercise, the oxygen supply to our muscle cells is limited. When oxygen is low, our muscle cells will utilize anaerobic respiration and ferment pyruvate into lactic acid. With rest and time, our body will eliminate the lactic acid and our muscles will no longer be sore. When we aren’t exercising, our muscle cells primarily use aerobic respiration because oxygen is plentiful.
