Matter that undergoes a physical change has the same chemical make up as the product. For example, when ice melts, the liquid water and ice are still water with the formula H2O. In a chemical change, matter does undergo a change, so that it is no longer the same substance that you started with. For example, magnesium plus hydrochloric acid react to produce the products magnesium chloride and hydrogen gas. So the products are completely different from the reactants.

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).
When ice melts is it a physical change or a chemical change?
It is a physical change. There is no chemical reaction whatsoever.
Is adding antifreeze to your radiator a chemical or physical change?
Adding antifreeze to your radiator is a physical change because the antifreeze retains its chemical composition and properties when mixed with the water in the radiator. It does not undergo a chemical reaction to form a new substance.
Reaction of copper and heat is physical change or chemical change?
The reaction of copper with heat is a physical change because no new substances are formed. When copper is heated, it undergoes a change in state from solid to liquid without changing its chemical composition.
Is mixing acid with base a chemical or physical change?
Adding a base to an acid or vice versa in changing the chemical properties of that solution. In both cases you are neuralizing the solution. There might be a physical change as well, but it would depend on what chemicals where mixing. But this reaction will definitely have a chemical change.
Is dissolving a physical or chemical reaction?
a physical reaction for the chemical structure is not changing.
What is made from a chemical reaction?
In a chemical reaction something new is created. A chemical change is inreversible where as a physical change is. In a physical change nothing new is formed.
Is water a chemical reaction or a physical reaction?
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
What is chemical reaction physical reaction?
A physical change is one in which the chemical composition of the substance does not change. A chemical change is one in which new products are formed with their own unique chemical compositions and properties.
Is oxidizing Mercury physical or chemical change?

What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
Is acid neutralizing ability physical or chemical change?
