Use stoichiometry to determine the moles of HCl consumed to produce 2.6 moles of H2 in excess Al
In the balanced equation, it can be seen that 6 moles of HCl will produce 3 moles of H2
Consider the following reaction: 2 Al + 6 HCl → Al2Cl6 + 3 H2
How many moles of HCl are required to produce 2.6 moles of hydrogen? Assume that there is excess Al present:
A. 1.7 mol
B. 5.2 mol
C. 2.3 mol
D. 4.1 mol
E. 6.2 mol
