Question

Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction:

2Al(s)+3Cl2(g)→2AlCl3(s)

You are given 14.0 gg of aluminum and 19.0 g of chlorine gas.

 

If you had excess chlorine, how many moles of of aluminum chloride could be produced from 14.0 g of aluminum?
Express your answer to three significant figures and include the appropriate units.
In the following chemical reaction, 2 mol of A will
react with 1 mol of B to produce 1 mol of A2B
without anything left over:
2A +B→A2B
But what if you're given 2.8 mol of A and 3.2 mol
of B? The amount of product formed is limited by
the reactant that runs out first, called the limiting
reactant. To identify the limiting reactant, calculate
the amount of product formed from each amount of
reactant separately:
2.8 metA x
1 mol A2B
2 mełA
= 1.4 mol A2B
3.2 mełB x
1 mol A2B
1 mełB
= 3.2 mol A2B
Notice that less product is formed with the given
amount of reactant A. Thus, A is the limiting
reactant, and a maximum of 1.4 mol of A2B can
be formed from the given amounts.
