Question

Iron reacts with cl2 according to the equation 2 fe(s) + 3 cl2(g) ? 2 fecl3(s). how many moles of cl2 is needed to react with 4.4 mol fe?

Answer 1

Answer: The amount of chlorine gas needed to react are 6.6 moles.

Step-by-step explanation:

We are given:

Moles of iron = 4.4 moles

For the given chemical equation:

`2Fe(s)+3Cl_2(g)\rightarrow 2FeCl_3(s)`

By Stoichiometry of the reaction:

2 moles of iron reacts with 3 moles of chlorine gas

So, 4.4 moles of iron will react with =
`(3)/(2)* 4.4=6.6mol` of chlorine gas

Hence, the amount of chlorine gas needed to react are 6.6 moles.
