Balance each of the following equations:a. Mg(s) + AgNO3(aq) ? Mg(NO3)2(aq) + Ag(s)b. CuCO3(s) ? CuO(s) + CO2(g)c. d. Pb(NO3)2(aq) + NaCl(aq) ? PbCl2(s) + NaNO3(aq)e. Al(s) + HCl(aq) ? AlCl3(aq) + H2(g)
ANSWER:Solution 5QP:Here we have to balance each of the following equations.When the number of mole of reactant is equal to the number of mole of product then a reaction is said to be balanced.Step-1a. Mg(s) + AgNO3(aq) Mg(NO3)2(aq) + Ag(s)In the above reaction the number of mole of NO3 in the product is two whereas in reactant it is 1 mole. In order to balance the total number of NO3 in both sides we have to multiply 2 in reactant side (2 AgNO3), now Ag atom in the reactant will be 2 mole whereas in product it is one mole. To balance the Ag atom we have to multiply 2 with Ag in product sideThus the balanced chemical equation is, Mg(s) + 2AgNO3(aq) Mg(NO3
