Question

write the skeletal equation and balance the following

Answer 1

Answer: Balanced skeletal equations of the given reactions are given below.

Explanation:

Skeletal equations are defined as the equations in which formula are used to indicate the chemicals that are involved in a chemical reaction.

The equations for the chemical reactions are given as:

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

$xi.)2Mg+3N_2\rightarrow 2MgN_3\\xii.)CuO+H_2\rightarrow Cu+H_2O\\xiii.)KI+AgNO_3\rightarrow AgI+KNO_3\\xiv.)3BaCl_2+Al_2(SO_4)_3\rightarrow 2AlCl_3+3BaSO_4\\xv.)MnO_2+4HCl\rightarrow MnCl_2+2H_2O+Cl_2\\xvi.)2Pb(NO_3)_2\rightarrow 2PbO+4NO_2+O_2\\xvii.)NH_4Cl\rightarrow NH_3+HCl\\xviii.)Ca(OH)_2+CO_2\rightarrow CaCO_3+H_2O\\xix.)Fe+H_2O(g)\rightarrow Fe_3O_4+2H_2O\\xx.)CaCO_3+H_2O+CO_2\rightarrow Ca(HCO_3)_2$
