Answer

Explanation:

Step1: Write reactants and products for first reaction

Reactants are $HCl(aq)$ and $MnO_2(s)$, products are $MnCl_2(aq)$, $H_2O(l)$ and $Cl_2(g)$. The un - balanced equation is $HCl(aq)+MnO_2(s)\rightarrow MnCl_2(aq)+H_2O(l)+Cl_2(g)$.

Step2: Balance the first equation

By adjusting coefficients, we get $4HCl(aq)+MnO_2(s)\rightarrow MnCl_2(aq)+2H_2O(l)+Cl_2(g)$.

Step3: Write reactants and products for second reaction

Reactants are $C_7H_{16}(l)$ and $O_2(g)$, products are $CO_2(g)$ and $H_2O(l)$. The un - balanced equation is $C_7H_{16}(l)+O_2(g)\rightarrow CO_2(g)+H_2O(l)$.

Step4: Balance the second equation

By adjusting coefficients, we get $C_7H_{16}(l)+11O_2(g)\rightarrow 7CO_2(g)+8H_2O(l)$.

Answer:

$4HCl(aq)+MnO_2(s)\rightarrow MnCl_2(aq)+2H_2O(l)+Cl_2(g)$ $C_7H_{16}(l)+11O_2(g)\rightarrow 7CO_2(g)+8H_2O(l)$
