Translate the following statement into chemical equations and than balance the equations: a) Chlorine gas burns in hydrogen gas to give hydrogen chloride.
b) Hydrogen sulphide gas burns in air to give water and suphur oxide.
c) Hydrogen gas combines with hydrogen to give ammonia, NH3
d) Sodium metal reacts with water to give sodium hydroxide and hydrogen gas
e) aluminium metal replaces iron from ferric oxide Fe2O3, giving aluminium oxide and iron.
