Aluminum metal reacts with chlorine gas to form aluminum chloride according to the balanced equation
2Al(s)+3Cl2(g)→2AlCl3(s)
A sample containing 10.0g of Al is placed in a vessel with 25.0g of Cl2. After the reaction goes to completion, the solid product is isolated.
(a) Calculate the number of moles of each reactant initially present.
(b) Identify the limiting reactant. Justify your choice with appropriate numerical evidence.
(c) Determine the theoretical mass (in grams) of AlCl3 that can be produced.
(d) Calculate the mass of the excess reactant that remains unreacted after completion of the reaction.
