which coefficient is needed in front of nano3 to balance the equation na2s + zn(no3)2 → zns + _nano3?\n1\n2\n5\n7
Answer
Explanation:
Step1: Count sodium atoms on left - hand side
The reactant $\text{Na}_2\text{S}$ has 2 sodium (Na) atoms.
Step2: Determine coefficient for $\text{NaNO}_3$
To balance sodium atoms on the right - hand side, since each $\text{NaNO}_3$ has 1 Na atom, we need 2 $\text{NaNO}_3$ to match the 2 Na atoms from $\text{Na}_2\text{S}$. The balanced equation is $\text{Na}_2\text{S}+\text{Zn}(\text{NO}_3)_2\rightarrow\text{ZnS} + 2\text{NaNO}_3$.
