What changes are evidence for a chemical change?
Remember that a chemical change is anything that alters the identity or composition of a substance. So something such as color change, a solid being formed, a gas being produced or temperature changing would constitute a chemical change.

What kind of change occurs with a new substance being formed?
Chemical change.
What is concentration per unit time?
Concentration per unit time, also known as rate of change of concentration, is a measure of how quickly the concentration of a substance is changing with respect to time. It indicates the speed at which a substance is being produced or consumed in a reaction or process. This can be calculated by dividing the change in concentration by the time interval over which the change occurred.
What you see when gas is produced?
When gas is produced, you may observe bubbles forming in the liquid or substance, a change in volume or pressure, and possibly a release of gas with accompanying hissing or popping sounds. Depending on the type of gas and how it is being produced, there may also be changes in color or temperature.
