Glossary Terms for Chapter 3 Flashcards
What is aerobic respiration?
Aerobic respiration is a reaction that uses oxygen to release energy stored in glucose
What is anodising?
Anodising is a way of protecting aluminium from corrosion, by deliberately creating a layer of aluminium oxide over it
What is a balanced formula equation?
A balanced formula equation is a chemical equation that has the same number of each atom on both sides of the arrow
What is combustion?
Combustion is a rapid reaction with oxygen that releases energy in the form of heat and
/ or light: and explosion etc.
What is complete combustion?
Complete combustion is combustion that occurs when there is plenty of oxygen. It produces carbon dioxide and water vapour.
What is corrosion?
Corrosion is the breakdown of metals due to their reaction with order chemicals.
A good example of this is rust
What is glucose?
Glucose is a type of sugar produced by photosynthesis, and has the chemical formula of C16H12O6
What are hydrocarbons?
Hydrocarbons are highly combustible chemicals. Petrol is a mixture of hydrocarbons.
Define incomplete combustion
Incomplete combustion is combustion that occurs when here is limited oxygen.
It produces carbon (soot, smoke) and carbon monoxide: CO
It doesn’t release as much heat or light as complete combustion.
What is the Law of Conservation and Mass?
The Law of Conservation and Mass States that atoms are not created or destroyed in a chemical reaction, only rearranged.
Describe photosynthesis.
Photosynthesis is an endothermic reaction that takes place in green plants. It uses energy from sunlight to combine water and carbon dioxide to produce glucose and oxygen gas
Products are…
…chemicals written on the righ side of the arrow
Reactants are…
…chemicals on the left side of the arrow
What is tarnish?
Tarnish is a black coating of silver sulfide that is produced when silver reacts with Sulfur in the atmosphere. The chemical formula is Ag2S
What is verdigris?
Verdigris is a green coating of copper hydroxide that is produced when copper reacts with moisture, CO2 and O2.
It’s chemical formula is Cu(OH)2
