- Question 9
- Mass is created during a chemical reaction.
- Mass can be converted into energy during chemical reactions.
- Mass is sometimes lost in chemical reactions.
- The total mass of reactants equals the total mass of products.
- Question 10
- Reactants are always gases, while products are always solids.
- Reactants are never changed during a reaction, while products are always altered.
- Reactants are produced after the reaction while products are involved before.
- Reactants are the starting substances and products are the substances formed.

- Endothermic reactions release energy, while exothermic reactions absorb energy.
- Exothermic reactions are always irreversible, while endothermic reactions can be reversible.
- Exothermic reactions are typically faster than endothermic reactions.
- Question 14
- Current is always constant in parallel circuits.
- Current equals voltage multiplied by resistance.
- Current indicates the power consumption of an electrical device.
- Current is the measure of charge flow per unit time.
- Question 15
- Eliminating any excess reactants to maintain simplicity.
- Changing the coefficients of reactants and products to achieve equal atoms of each element.
