What information can you determine from the coefficients of this balanced chemical equation? mg+2hcl --> mgcl2+h2 formula ratio mole ratio mass ration volume ration

second option: mole ratio.

Explanation:

The coefficients of the chemical equation, when balanced, indicate the number ratio in which compounds combine with each other.

In the given equation, Mg+2HCl -->MgCl₂+H₂

1 mole of Mg combines with 2 moles of HCl and produce 1 mole of MgCl₂ and 1 mol of H2.

So, the mole ratio is

1 mol Mg : 2 mol HCl : 1 mol MgCl₂ : 1 mol H₂.

In general, in a balanced equation of the kind aA + bB → cC + dD

The mole ratio is:

a mol of A : b mol of B : c mol of C : d mol D.
