How many moles of hydrogen gas would be produced in the reaction that yields 7.5 moles of iron chloride?
Reaction: 2Fe+6HCl=3H2+2FeCl3

Question

jfraser · Answer

you need a balanced reaction first, what are the other pieces of the reaction?

I just fixed it haha sorry

jfraser · Answer

look at the molar ratios of the two products: every time 2 moles of iron (III) chloride are produced, 3 moles of H2 are also produced. Use that same ratio to apply to the problem that produces 7.5 moles of iron (III) chloride
