A gas is given off that turns limewater milky, and a white solid remains.
Which type of reaction has occurred?
- Thermal decomposition because one compound breaks into two simpler substances.
- Neutralisation because an acid reacts with a base to form salt and water.
- Oxidation because calcium gains oxygen from the air.
- Displacement because calcium displaces carbon from its compound.
