Write down the equations of chemical reactions according to the description: a) when iron (III) oxide Fe2O3 interacts

Write down the equations of chemical reactions according to the description:
a) when iron (III) oxide Fe2O3 interacts with hydrogen, iron and water are formed;
b) chlorine Cl2 interacts with aluminum to form aluminum chloride AlCl3;
c) the reaction between sodium and nitrogen N2 leads to the formation of sodium nitride Na3N.

a) when iron (III) oxide Fe2O3 interacts with hydrogen, iron and water are formed;
2Fe2O3 + 6H2 = 2Fe + 6H2O
b) chlorine Cl2 interacts with aluminum to form aluminum chloride AlCl3;
3Cl2 + 2Al = 2AlCl3
c) the reaction between sodium and nitrogen N2 leads to the formation of sodium nitride Na3N.
6Na + N2 = 2Na3N
