Part A
Describe the type of change in matter that occurred in thisinvestigation and provide evidence to support your response.

Part B
Describe a chemical property of baking soda.

Part C
Explain how the results of the investigation support the Law of Conservation of Matter.

Part D
Provide a brief explanation whythe investigation measurements differed.

Answer:

part b:

Sodium bicarbonate is a white, crystalline powder that sometimes forms lumps. It is odorless and has a bitter, salty taste. At room temperature, it is a solid. Solubility, or the ability of a substance to dissolve in water, is also a physical property. Sodium bicarbonate is soluble in water and can be separated from water through evaporation.

Explanation:

In the reaction of baking soda with acetic acid carbon dioxide gas is evolved that's why the balloon inflates. The mass in the product side and reactant side ar equal and the the total mass is conserved.

According law of conservation of mass, mass can neither be created nor be destroyed. Therefore, the total mass of a system will be conserved. In a chemical reaction, the total mass of reactants is equal to the total mass of products and thus no mass loss occur there.

In the reaction of vinegar (acetic acid) and sodium bicarbonate or baking soda, the mass on both side is equal and we get the product mass equal to the total mass of reactants if the experiment is carefully done.

Sodium carbonate is a colourless weak base, which can easily react with an acid and gets protonated. When sodium bicarbonate that is NaHCO₃, with vinegar CH₃COOH, it will produce carbon dioxide and water.

This carbon dioxide gas evolves to the balloon which is stretched on the top and the balloon will inflates.The measurements will differ at each moment because we are measuring it in different events of the reaction where the gas is evolving out.
