This is the equation for the formation of magnesium chloride.
Mg(s) + 2HCl(l) → MgCl2(aq) + H2(g)
Which are the reactants and the products in this reaction?
A. The reactants are MgCl2 (magnesium chloride) and H2 (hydrogen); the products are Mg (magnesium) and HCl (hydrochloric acid).
B. The reactants are MgCl2 (magnesium chloride) and HCl (hydrochloric acid); the products are Mg (magnesium) and H2 (hydrogen).
C. The reactants are Mg (magnesium) and H2 (hydrogen); the products are MgCl2 (magnesium chloride) and HCl (hydrochloric acid).
D. The reactants are Mg (magnesium) and HCl (hydrochloric acid); the products are MgCl2 (magnesium chloride)and H2 (hydrogen).
The reactants are those which react with each other to give the desired result. The product is this result of reactants. Thus, here option "D." Is correct.
