QUESTION:
Consider the reaction between \(\mathrm{NiS}_{2}\) and \(\mathrm{O}_{2}\):
\(2 \mathrm{NiS}_{2}(s)+5 \mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{NiO}(s)+4 \mathrm{SO}_{2}(g)\)
When 11.2 g of \(\mathrm{NiS}_{2}\) react with 5.43 g of \(\mathrm{O}_{2}\), 4.86 g of NiO are obtained. Determine the limiting reactant, theoretical yield of NiO, and percent yield for the reaction.
ANSWER:Step 1 of 3
We have the equation,
\(2{\rm{Ni}}{{\rm{S}}_2} + 5{{\rm{O}}_2}\left( g \right) \to 2{\rm{NiO}}\left( s \right) + 4{\rm{S}}{{\rm{O}}_2}\left( g \right)\)
\({\rm{Moles}}\;{\rm{of}}\;{\rm{Ni}}{{\rm{S}}_2} = \frac{{11.2}}{{122.8}} = 0.09\;{\rm{mol}}\)
\({\rm{Moles}}\;{\rm{of}}\;{O_2} = \frac{{5.43}}{{32}} = 0.17\;{\rm{mol}}\)
\({\rm{Moles}}\;{\rm{of}}\;{\rm{NiO}} = \frac{{4.86}}{{74.69}} = 0.065\;{\rm{mol}}\)
Step 2 of 3
Since the mole ratio for \
