D.
the total mass of the products will be equal to the original mass of the reactants.
Explanation:
Ca + 2H₂O → Ca(OH)₂ + H₂
From this chemical reaction, one can conclude that when the reaction reaches completion, the total mass of the products will be equal to the original mass of the reactants. This is in compliance with the law of conservation of mass.
- The law of conservation of mass states that matter is the mass of products in a chemical reaction is the same as mass of the reactants.
- This implies that the mass of the products in a given reaction is the same as that of the reactants.
- No mass is lost in the process of a chemical change.

D i hope it helps i not that smart
Primary consumers eat plants, which are producers. Producers are essentially he beginning of the food chain. Secondary consumers eat primary consumers. This means that organisms who are both primary and secondary consumers are omnivores.
