Problem

An experiment shows that 0.60 mol of aluminum metal reacts completely with 0.90 mol of chlorine gas to form aluminum chloride as the only product. Which of the following balanced chemical equations is most consistent with these data? (a) Al+Cl2→AlCl3Al + Cl_{2} \rightarrow AlCl_{3} (b) 2 Al+3 Cl2→2 AlCl32\,Al + 3\,Cl_{2} \rightarrow 2\,AlCl_{3} (c) 3 Al+2 Cl2→2 AlCl33\,Al + 2\,Cl_{2} \rightarrow 2\,AlCl_{3} (d) 2 Al+Cl2→2 AlCl2\,Al + Cl_{2} \rightarrow 2\,AlCl
