Chlorine gas can be made from the reaction of manganese dioxide with hydrochloric acid.MnO₂(s) + 4HCl(aq) $\rarr$ MnCl₂(aq) + 2H₂O(l) + Cl₂(g) According to the above reaction, determine the limiting reactant when 5.6 moles of MnO₂ are reacted with 7.5 moles of HCl.

Question

Quizplus · Accepted Answer

To determine the limiting reactant, we need to compare the moles of each reactant to their respective coefficients in the balanced equation.

For MnO2: 
5.6 moles × (1 mole MnO2/1) = 5.6 moles MnO2

For HCl: 
7.5 moles × (4 moles HCl/1) = 30 moles HCl

Since the coefficient of MnO2 is 1 and the coefficient of HCl is 4, we can see that HCl has a larger stoichiometric coefficient, meaning it requires more moles to react with one mole of MnO2. Therefore, HCl is the limiting reactant in this reaction.
