Based on two of the mole ratios between substances in a chemical reaction, which is the correct equation for the chemical reaction?

d) A  + 2B   →   3C

Explanation:

In given question the there are one mole of reactant A two moles of reactant B and three moles of product C are present.

1 mol A / 2 mol B                 1 mol A / 3 mol C

A : B     1 : 2                          A : C     1 :  3

So from given information option D is correct.

A  + 2B   →   3C

Here in this equation one mole of A , two moles of B and three moles of C are present.

Other options are incorrect because,

a) 3A  + 2B   →   C

In this chemical equation three  moles of A two moles of B and one mole of C are present. So it is incorrect.

b) A + B →   C

In this chemical equation one mole of A one mole of B and one mole of C are present. So it is incorrect.

C) 6A +6B →   2C

In this chemical equation six moles of A six moles of B and two mole of C are present. So it is incorrect.
