The chemical equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) is shown.
Mg + 2HCl → MgCl2 + H2
Fiona weighs the magnesium and hydrochloric acid before the reaction and finds a total mass of 55 grams. After the reaction, she measures the mass of the products, magnesium chloride (MgCl2) and hydrogen (H2), and finds a total mass of 55 grams again. Does Fiona's data support the law of conservation of matter, and why?
a
No, because the mass of the reactants is the same as the mass of the products in her data.
b
Yes, because the mass of the reactants is lower than the mass of the products in her data.
c
No, because the mass of the reactants is lower than the mass of the products in her data.
d
Yes, because the mass of the reactants is the same as the mass of the products in her data.
