Reactions Flashcards
1
Q
What is thermal decomposition
A
When a compound gets broken down by very high heat. This is an endothermic reaction. e.g. copper carbonate → copper oxide + carbon dioxide
2
Q
oxidisation
A
a reaction with oxygen
3
Q
Word equation for metal and acid
A
Metal + acid → salt + hydrogen
4
Q
reaction for metal carbonates and acid
A
acid + carbonate → salt + carbon dioxide + water.
5
Q
What is neutralisation
A
When an alkali or an acid is neutralised to move the pH towards 7. It is an exothermic process
6
Q
Precipitation
A
When an insoluble solid is formed.
7
Q
Conservation of mass law
A
When a physical or chemical reaction happens, an object will not gain or lose mass.
