Answer 2

Answer: The 20 balanced chemical equation is given below.

Explanation:

Balanced chemical equation is defined as the equation which follows law of conservation of mass. In this the number of atoms on the reactant side must be equal to the number of atoms on the product side. The total mass of the reaction remains constant.

The 20 balanced chemical equations are given below:

1. $2H_2+O_2\rightarrow 2H_2O$
2. $H_2+Cl_2\rightarrow 2HCl$
3. $PbSO_4+Zn\rightarrow ZnSO_4+Pb$
4. $4B+3O_2\rightarrow 2B_2O_3$
5. $2Al+6HCl\rightarrow 2AlCl_3+3H_2$
6. $N_2+O_2\rightarrow 2NO$
7. $P_4+3O_2\rightarrow P_4O_6$
8. $4NH_3+5O_2\rightarrow 6H_2O+4NO$
9. $Mg+2HNO_3\rightarrow Mg(NO_3)_2+H_2$
10. $Hg+S\rightarrow HgS$
11. $CaO+SO_2\rightarrow CaSO_3$
12. $MgO+H_2SO_4\rightarrow MgSO_4+H_2O$
13. $Zn+2H_2O\rightarrow Zn(OH)_2+H_2$
14. $MgSO_4+Na_2CO_3\rightarrow MgCO_3+Na_2SO_4$
15. $Cl_2+2F_2\rightarrow 2ClF_3$
16. $Xe+3F_2\rightarrow XeF_6$
17. $Al_2O_3.2H_2O\rightarrow Al_2O_3+2H_2O$
18. $2PbS+3O_2\rightarrow 2PbO+2SO_2$
19. $2HgO\rightarrow 2Hg+O_2$
20. $Cr_2O_3+2Al\rightarrow Al_2O_3+2Cr$
