Question

during a slime - making lab, some students accidentally spill a little glue after weighing it as a reactant. how does this affect the results of mass? the mass of products will equal the mass of reactants the mass of products will appear less than the mass of reactants the mass of products will appear more than the mass of reactants spills do not affect mass

Explanation:

According to the law of conservation of mass, in a chemical reaction, the total mass of reactants equals the total mass of products. But since some of the weighed - reactant (glue) is spilled before reacting, the amount of reactant that actually participates in the reaction is less than the initially - weighed amount. So, the mass of products formed will be less than what would have been formed if all the initially - weighed reactant had reacted, making the mass of products appear less than the initially - weighed mass of reactants.

Answer:

The mass of products will appear less than the mass of reactants
