Consider the unbalanced reaction NiS2(s) + O2(g) --> NiO(s) + SO2(g) When 10.7 g of NiS2 react with 6.11 g of O2, 4.86 g of NiO are obtained.
The theoretical yield of NiO is (number and unit)
the limiting reactant is (name or symbol) and
the percent yield is (number) %. (Remember to use correct sig figs)
