The chemical change that produces acetylene gas is the reaction between calcium carbide (CaC2) and water. This reaction forms calcium hydroxide (Ca(OH)2) and acetylene gas (C2H2).

Copper turns green due to a chemical reaction with oxygen and other elements in the environment, forming a layer of copper oxide and copper carbonate on the surface. This process is known as oxidation and is a chemical change.
It is a chemical change. The bleach reacts with the pigments in the hair, causing a chemical reaction that breaks down the natural color and can result in a yellowish tint.
The color change of copper to green is a chemical change. This is due to the formation of a green patina on the surface of the copper, typically caused by oxidation reactions with the air and moisture.
The process of LPG turning from liquid to gas is a physical change, not a chemical change. It involves a change in state, from liquid to gas, without any alteration in the chemical composition of the LPG molecules.

The conversion of starch in the pizza crust to sugar is a chemical change. This process, known as hydrolysis, involves the breaking down of starch molecules into sugar molecules by reacting with water.

Photosynthesis is a chemical reaction. Using Sunlight, water, and carbon dioxide, plants can produce high energy sugars and oxygen. Here is the formula:Sunlight + 6H2O + 6CO2 ----> C6H12O6, 6O2

Yes.
I'm not sure. I think it is a chemical change.
Signs of chemical change are when a substance changes into a new substance. Like Paper being burned turns into gray powder. That is a chemical change.
the mass of the property does not change
