Homework Statement
When aluminum reacts with chlorine
how much heat in KJ is released on reaction of 5.00 g of Al
for the following reaction:
2AL (s) + 3 CL2(g) ----->2AlCl3 (s)
delta h = -1408.4
Homework Equations
The Attempt at a Solution
Is it right if you start multiplying the delta H by the number of grams of Al , and by doing that by first converting grams of Al to moles? It's hard to tell you if you would divide by 2 at all? 2Al has something to do with it maybe?
