If a piece of metal bubbles was place in acid is that a chemical change?
No, it is not a chemical change. For example, if you put gold bubbles into any single acid, no chemical change will take place.
Is corrosion of aluminium metal a physical change or a chemical change?
It is a chemical change. Through corrosion, a chemical reaction has taken place.
What identifies a chemical change has taken place?
Signs that a chemical change has taken place include the formation of a gas, the formation of a precipitate, a change in temperature, and a change in color.

Is reaction with acid a physical or chemical property?
A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
