Henry puts 2. 0 grams of baking soda into a 1. 0 gram plastic bag. He then pours 5. 0 grams of vinegar into the bag and immediately closes it. A reaction takes place. Henry observes a gas being produced, and the plastic bag with the baking soda and vinegar becomes cold to the touch. What will be the total mass of the bag and its contents after the reaction?.

When atoms establish or break chemical bonds, chemical processes take place. Reactants are the substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction.

Mass cannot be created or destroyed, under the law of conservation of mass. As a result, the mass of reactants and products must be equal. Each element must have the same number of atoms on both the reactant and product sides. Chemical equations are balanced as a result.

2.0 g + 5.0 g = 7.0 g is the mass of the reactants.

mass of the bag is 1 g.

Consequently, the weight of the products plus the weight of the bag is equal to 7.0 g plus 1.0 g, which equals 8.0 g.
