URGENT!!!! I WILL GIVE BRAINLIEST!! HELP ASAP!


A student adds 5 grams of baking soda to a beaker of vinegar (acetic acid) weighing 10 grams. He observes a significant amount of bubbles form as soon as the two substances are combined.

After the reaction, the mass of the products remaining in the beaker is 13 g. Does this reaction follow the law of conservation of matter? Explain your reasoning.

Yes, the reaction follows the law of conservation of matter.

Law of conservation of matter states that matter can neither be created nor destroyed but can be transformed from one form to another.

In a closed system, the total amount of matter before an after reaction is constant.

The total mass of the reactant before reaction is given as;

5 grams of baking soda +  10 grams of vinegar

The total mass of the product after reaction is given as;

13 grams  +  gases escaped as bubbles

Thus, we can conclude that the reaction follows the law of conservation of matter.
