Question

1. A student mixes baking soda and vinegar in a glass. Do you think any new substances are being created in this mixture? If so, how do you know?
2. Suppose this was done on top of a balance. Do you think the mass would change as the reaction proceeded?

3. What do you think would happen to the mass if the reaction took place inside a sealed plastic bag?

Answer 1

Answer:

Explanation:

1.) An acid base reaction occurs since we know that vinagar is just acetic acid and baking soda is just sodium bicarbonate. The vinagar (weak acid) is going to react with the bicarbonate (weak base) to create carbonic acid which decomposes into carbon dioxide and water. I hope this helps. Let me know in the comments if anything is unclear.
