Answer 1

Explanation;

Imbalanced equations;

$i.)Fe_2O_3+Al\rightarrow Al_2O_3+Fe\\ii.)Na+H_2O\rightarrow NaOH+H_2\\iii.)H_2S+SO_2\rightarrow S+H_2O\\iv.)CH_4+O_2\rightarrow CO_2+H_2O\\v.)PbO+C\rightarrow Pb+CO_2\\vi.)ZnO+C\rightarrow Zn+CO\\vii.)Mg+HCl\rightarrow MgCl_2+H_2\\viii.)Mg+H_2SO_4\rightarrow MgSO_4+H_2\\ix.)Cu+AgNO_3\rightarrow Cu(NO_3)_2+Ag\\x.)Pb(NO_3)_2+H_2SO_4\rightarrow PbSO_4+HNO_3$

Balanced equations:

$i.)Fe_2O_3+2Al\rightarrow Al_2O_3+2Fe\\ii.)2Na+2H_2O\rightarrow 2NaOH+H_2\\iii.)2H_2S+SO_2\rightarrow 3S+2H_2O\\iv.)CH_4+2O_2\rightarrow CO_2+2H_2O\\v.)2PbO+C\rightarrow 2Pb+CO_2\\vi.)ZnO+C\rightarrow Zn+CO\\vii.)Mg+2HCl\rightarrow MgCl_2+H_2\\viii.)Mg+H_2SO_4\rightarrow MgSO_4+H_2\\ix.)Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag\\x.)Pb(NO_3)_2+H_2SO_4\rightarrow PbSO_4+2HNO_3$
