Caren predicts that the mass of the products will be 76 g. According to the law of conservation of matter, is Caren's prediction reasonable? Why or why not?

a
Her prediction is unreasonable because the law of conservation of matter states that some mass is lost in a chemical reaction, so the mass of the products will be less than 64 g.
b
Her prediction is reasonable because the law of conservation of matter states that the products of a reaction have more mass than the reactants.
c
Her prediction is reasonable because the law of conservation of matter states that matter can neither be created nor destroyed in a chemical reaction.
d
Her prediction is unreasonable because the law of conservation of matter states that matter can neither be created nor destroyed, so the mass of the products will be 64 g.

c

Her prediction is reasonable because the law of conservation of matter states that matter can neither be created nor destroyed in a chemical reaction. Therefore, the mass of the products should equal the mass of the reactants.
