What is a compound, molecule, or formula?

400

This reaction is where a larger compound is broken down into smaller compounds.

What is a decomposition

400

Why did we put a balloon on the Erlenmeyer flask when reacting baking soda and vinegar?

We needed a weight after the reaction, so we had to trap the gas.
