6CO2 + 6H2O + light energy = C6H12O6 + 6O2

Carbon dioxide + water + light energy yields glucose + oxygen

A process in plants which uses sunlight to make food from carbon dioxide and water. Chlorophyll is involved in the process as well. The light from the sun is absorbed into the leaves and reacts with carbon dioxide and water to make food for the plant. Plants need this process to make food for themselves and provides us with oxygen to survive.

Aerobic Cellular Respiration

C6H12O6 + 6O2 = 6CO2 + 6H2O + heat

glucose + oxygen yields carbon dioxide + water + heat

A process in the cells of organisms which uses oxygen to create ATP, or adenosine triphosphate. It uses nutrients to make energy in the cells and then releases waste products. It uses highly oxidizing substances like molecular oxygen. It is also considered an exothermic redox reaction because it produces heat. This reaction provides our bodies with energy.

Anaerobic Respiration

C6H12O6 = 2C3H6O3 + E

Glucose yields lactic acid + energy

Respiration which shuttles electrons to an electron transport chain and then to its final electron acceptor, oxygen. Anaerobic respiration uses less oxidizing substances like sulfate or nitrate. These reactions produce less energy than anaerobic reactions do, but still gives our bodies energy. This is a process of producing cellular energy without oxygen. It is a very fast reaction that produces 2 ATP.

Hydrocarbon Combustion

CH4 + 2O2 = CO2 + 2H2O

Hydrocarbon + oxygen yields carbon dioxide + water

A reaction between a gas and an oxidant that produces carbon dioxide and water. It is often hot enough that a glow or flame could be produced. An example of this reaction would be a camp fire. This reaction is important because it produces fire. Fire is very essential for cooking, heat, and light.

Rusting of Iron

4Fe + 3O2 + H2O = 4Fe(OH)3

iron + oxygen + water = iron III hydroxide

When iron or steel rust, they come in contact with water and oxygen. Acid rain and salt water makes metals rust faster. Some metals, like aluminum, don't rust easy because the surface is protected by aluminum oxide. When iron rusts, it shows when it needs to be replaced.

Synthesis of Sulfuric Acid

H2S2O7 + H2O = 2H2SO4

oleum + water = sulfuric acid

This reaction makes a very dangerous chemical. The reaction is highly exothermic and should always be performed by adding acid to water rather than vice versa. Drops of sulfuric acid can decompose things by dehydration. It is used to make hundreds of compounds.
