Question

What coefficients are necessary to balance this:

Mg + HCl ---> H2 + MgCl21,2,2,1

a) 1,2,2,1
b) 1,1,1,1
c) 1,2,1,1
d) 2,4,2,2

Answer 1

The balanced equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) is:Mg + 2HCl → H2 + MgCl2The coefficients in the balanced equation represent the relative numbers of molecules or moles of each substance involved in the reaction. The correct coefficients to balance the equation are:a) 1,2,2,1Therefore, option (a) is the correct answer.
