JudyChemical reactions of water, oxygen, and acids on rocks can eventually produce weathering, erosion, and ultimately, the breakdown of the rocks into smaller particles like sand, silt, and clay. This process, known as chemical weathering, leads to the formation of new minerals and soil over time.

What chemical reactions yield water?
The chemical reactions that yield water include combustion (burning), where hydrocarbons combine with oxygen to produce carbon dioxide and water; the reaction between acids and bases which can produce water; and the synthesis reaction between hydrogen gas and oxygen gas to form water.
Is oxygen a reactant?
Yes, oxygen is a reactant in many chemical reactions, particularly combustion reactions where it combines with other substances to produce energy.
What are some ways to produce oxygen?
Some ways to produce oxygen include photosynthesis by plants and algae, electrolysis of water to split water molecules into oxygen and hydrogen, and using certain chemical reactions to release oxygen gas.
Are glow sticks an example of a combustion reaction?
No, glow sticks use a chemical reaction called chemiluminescence, not combustion. Combustion reactions typically involve the reaction of a substance with oxygen to produce heat and light, while chemiluminescence involves the emission of light as a result of a chemical reaction without producing significant heat.
How does chemical reaction occur in a coal?
Coal is primarily composed of carbon, which can undergo chemical reactions such as combustion when exposed to heat and oxygen. When coal is heated, the carbon in it reacts with oxygen in the air to produce carbon dioxide and heat energy. This is the basis of how chemical reactions occur in coal.
