The correct answer for this question is option C, which states that "the total mass of the reactants must equal the total mass of the products."
Explanation:
Chemical reactions involve the rearrangement of atoms to form new substances. According to the law of conservation of mass, matter is neither created nor destroyed during a chemical reaction. This means that the total mass of the reactants must be equal to the total mass of the products.
Here's a breakdown of the explanation:
1. Conservation of Mass:
- The law of conservation of mass states that the total mass of the reactants in a chemical reaction is always equal to the total mass of the products.
- This means that no atoms are gained or lost during a chemical reaction. The atoms simply rearrange to form new substances.
2. Reactants and Products:
- Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.
- The reactants undergo a chemical change and are transformed into products.
3. Complete Reaction:
- When all the reactants are completely used up in a reaction, it indicates that the reaction has gone to completion.
- In a complete reaction, all the reactant molecules have been converted into product molecules.
4. Conservation of Mass in Complete Reaction:
- Since no atoms are gained or lost during a chemical reaction, the total mass of the reactants must be equal to the total mass of the products.
- This is because the same atoms that make up the reactants are rearranged to form the products.
Therefore, in a chemical reaction where all the reactants are completely used, the total mass of the reactants must equal the total mass of the products. This is in accordance with the law of conservation of mass.
