Andre adds a spoonful of baking soda to a glass of vinegar. bubbles begin to appear in the vinegar. the bubbles signal the formation of a(n)

The answer is Compound

Expanation - The vinegar, an acid, chemically reacts with the baking soda, a base, resulting in the formation of carbon dioxide gas (which causes the bubbles) and water. So, the bubbles signal the formation of a compound, carbon dioxide.

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
