Question

3a) Aluminum reacts with chlorine gas to form aluminum chloride, What is its balanced equation?

3b)Determine the limiting reactant between 34.0 g of aluminum and 39.0 g of chlorine gas.

Answer 1

3a) $2Al +3Cl_2\to2AlCl_3$

3b) moles of Al$=34/27=1.26moles$

moles of $Cl_2=39/71=0.549moles$

moles of chlorine is less than moles of aluminium, so it is the limiting reactant.
