What are three chemical changes that happen every day?

Answer 1

Frying eggs on a skillet (the heat alters the protein in the egg white)

Burning wood, coal, methane gas, oil

Degradation of fats by heating

Degradation of fruits, vegetables, wines by fermentation

Combustion of automotive fuels

Formation of nitrogen and sulfur oxides

Formation of ozone

Rusting of iron

Washing with detergents

Preparation of many foods

Answer 2

1.shotguns

2.see a fly be shotguned

3.a monkey shotgun noob

4.cake bombs

5.wild deer having sex

6.yourself

7.a numty eating

8.a poo

9.a death machine

10.a homasexul weirdo

Answer 3

One example of a chemical change that happens every day is a phase change in which matter goes from one state into another. The most common example is the melting of ice in which water goes from a solid to a liquid. The boiling of water changes the liquid to a vapor. Another example of a common chemical change is the redox reaction, in which electrons are transferred from one atom or molecule to another, usually with a large release of energy. Human metabolism is a redox reaction in which reduced carbon compounds (sugar) are oxidized into carbon dioxide and water with the release of heat and energy. A third example of a chemical change is dissolution or solvation in which a solid dissolves into a liquid (the solvent). Sugar or salt dissolved into water is a common example of solvation.

Answer 4

1. Cooking food: When food is cooked, chemical reactions occur that change the composition of the food, making it more easily digestible and altering its taste and texture.

2. Rusting of iron: When iron is exposed to oxygen in the air and moisture, a chemical reaction occurs that forms rust, changing the iron into a new substance with different properties.

3. Digestion: In the human body, food undergoes chemical changes in the digestive system, where enzymes break down complex molecules into simpler ones that can be absorbed and used by the body for energy and growth.

Answer 5

Combustion (burning), acid-base reactions (such as vinegar-baking soda), and photosynthesis (plants).

Answer 6

cellular respiration, anything burning nuclear plants, and batteries

Answer 7

Some of the everyday chemical reactions that we use daily include bleaching, baking and the cooking of eggs.
