Question

Observe the following balanced chemical reaction:

2 Fe + 3 Cl2 → 2 FeCl3

PLEASE HELP ASAP

Which of the following describes the mole ratio between Fe and Cl2?

2 mol Fe: 2 mol Cl2
1 mole Fe: 2 mole Cl2
2 mole Fe: 6 mol Cl2
2 mole Fe : 3 mol Cl2

Answer 1

The answer to your question is: the last option ( 2 mole Fe : 3 mol Cl2)

Step-by-step explanation:

The mole ratio in a chemical reaction is expressed by the integers before each element, for example if we have

2H2SO4 + 3NaOH,

The mole ratio between, H2SO4 and NaOH is 2H2SO4 : 3 NaOH

In your question, the question is the ratio between Fe and Cl2, so we look at their coefficients and then:

2 mole Fe : 3 mol Cl2
