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).

Is toasting bread an example of a physical or a chemical change?
Yes it is, as the browning of the bread when you toast it, is a reaction between the reducing sugar and amino acids. The reaction is called Maillard reaction.
