Question

A student adds 10 grams of vinegar to 7 grams of baking soda in a sealed container. Then he watches the chemical reaction that occurs. Which of these predicts the mass of the materials in the container after the reaction is complete?

Answer 1

The mass of the materials in the container after the reaction is complete can be predicted by considering the law of conservation of mass. The total mass of the reactants should be equal to the total mass of the products.

Step-by-step explanation:

The mass of the materials in the container after the reaction is complete can be predicted by considering the law of conservation of mass. According to this law, the mass of the reactants should be equal to the mass of the products. In this case, the reactants are 10 grams of vinegar and 7 grams of baking soda. After the reaction, the products are formed, which may include carbon dioxide gas and water.

So, the total mass of the reactants should be equal to the total mass of the products.
