Magnesium oxide can be made by heating magnesium metal in the presence of the oxygen. The balanced equation for the reaction is \( 2 \mathrm{Mg}(s)+\mathrm{O}_{2}(g) \rightarrow 2 \mathrm{MgO}(s) \) When \( 10.1 \mathrm{~g} \) of \( \mathrm{Mg} \) is allowed to react with \( 10.6 \mathrm{~g} \) \( \mathrm{O}_{2}, 11.8 \mathrm{~g} \mathrm{MgO} \) is collected. Part B Determine the theoretical yield for the reaction. Part C Determine the percent yield for the reaction.
Expert Answer
(B) As per the balnced Chemical equation given in the question we can conclude that- 2 moles of Magnesium metal combined with 1 mole of di-oxygen gas to gives out 2 moles of Magnesium oxide as the product.
