Question

If the combined mass of the reactants is 100 grams, then which of the following must be true? the combined mass of the products is 100 grams each product has a mass of 100 grams each reactant has the same mass as each product each reactant must produce 100 grams of product

Answer 1

Conservation of mass 100g reactants = 100g products. That is total mass of the reactants and products

Answer 2

Answer: A) the combined mass of the products is 100 grams.

Explanation: the law of conservation of mass (or matter) says that the total mass of any material system is neither increased nor diminished by reactions between the parts, this means that when we have a reaction, the mass combined mass of the reactants will be exactly the same as the combined mass of the products, so the correct answer is the corresponding to option A.
