|
Metals and Acids |
The metals corrode and break it down into salt and hydrogen gas. Acid + metal --> a salt and hydrogen gas Sulfric acid + iron --> iron sulfate + hydrogen gas |
|
|
Neutralisation |
Acids and bases neutralise each other when mixed, which changes them into harmless substances. Acid + base --> a salt + water Nitric acid + pottasium oxide --> potassium nitrate + water |
|
|
Acids and Carbonates |
It produces carbon dioxide as well as salt and water. Acid + carbonate --> a salt + water + carbon dioxide Hydrochlorlic acid + calcium carbonate --> calcium chloride + water + carbon dioxide |
|
|
Combustion |
A rapid action with oxygen that releases energy in the form of heat/light. |
|
|
Complete Combustion |
combustion that occurs when there is plenty of oxygen. it produces carbon dioxide and water vapour. |
|
|
Corrosion |
The breakdown of metals due to their reaction with other chemicals |
|
|
Endothermic |
a chemical reaction that absorbs energy |
|
|
Exothermic |
a chemical reaction that releases energy |
|
|
Incomplete combustion |
combustion that occurs when oxygen is limited. it produces carbon (soot, smoke) and carbon monoxide. It does not release as much heat or light as complete combustion. |
|
|
Products |
chemicals produced in a chemical reaction. They are written on the right hand side of the arrow/ |
|
|
Reactants |
chemicals that take part in a chemical reaction. they are written on the left hand side of the arrow. |
|
|
Rust |
hydrated iron(III) oxide |
|
|
Tarnish |
A black coating of silver sulfide that is produced when silver reacts with sulfur in the atmosphere. |
|
|
Verdigris |
A green coating of copper hydroxide that is produced when copper reacts with moisture, carbon dioxide and oxygen in the atmosphere. |
