A scientist conducts a chemical reaction. At the beginning of the reaction, she combines 5.4 grams of the first reactant and 6.3 grams of the second reactant. She runs the reaction in a closed chamber and heats only the reaction. A small amount of gas is produced. What can you conclude about the total mass of the substances present when the reaction is complete?

Jadyn Morrow · Answer 1

The total of the mass of the substances present should be approximately equal to the sum of the mass of the reactants or 11.7 g assuming that the mas of the gas produced is negligible or very small. This is to agree the law of conservation of mass where mass cannot be created nor destroyed.
