Question

Inegar and baking soda are mixed in a container; bubbles are formed, and the container feels slightly warm. This is most likely a: * 1 point Physical change because the substances are changing shape Physical change because the vinegar and baking soda are just mixing Chemical change because a new substance, a gas, is produced.

Answer 1

Chemical change because a new substance, a gas, is produced

Step-by-step explanation:

There are two types of changes that occurs in reactions viz: physical change and chemical change. Physical changes are those changes that does not alter the chemical composition of the reacting substances, hence, no new substances are formed e.g freezing, melting, change of state.

On the other hand, chemical changes affect the chemical composition of the reactants, hence, new substances characterized by increase in temperature, formation of gaseous bubbles occur.

In this case, vinegar and baking soda are mixed in a container, which resulted in the formation of bubbles and slight increase in the solution's temperature. This indicates that a CHEMICAL CHANGE occured because a new substance, a gas, is produced.
