Question

Consider the following unbalanced reaction: Al (s) + Cl₂ (g)→AlCl₃ (s) How many moles of Cl₂ (g) are required to react with 10 moles of Al?

Quizplus · Accepted Answer

From the balanced equation, we can see that the ratio of Al to Cl₂ is 1:3. Therefore, for every 1 mole of Al, we need 3 moles of Cl₂. Thus, 10 moles of Al will require 3 times as many moles of Cl₂, which is 30 moles. However, since we are looking for the minimum amount of Cl₂ required for the reaction, we need to divide 30 moles by the stoichiometric coefficient of Cl₂, which is 2. Therefore, we need 15 moles of Cl₂.
