physical change
A compound is the pure substance formed from the chemical combination of two or more different elements.
It's called a compound and water is an example.
The process of changing from a liquid to a solid is called solidification or freezing. This occurs when the temperature of a substance decreases below its freezing point, causing the molecules to slow down and arrange themselves into a stable solid state.
A product is a substance that is formed by a chemical reaction.
No, a car rusting is a chemical change because a new substance is formed. Iron will react with oxygen (found in water) forming iron oxide. The product, iron oxide, has different properties from both iron and oxygen. A "chemical change" describes any reaction where a new substance is formed. However, if a substance just changes forms, it is a physical change. For example, water freezing is a physical change.
No. The same would be when water melts or freezes. It is still water.

A compound.
A compound is the pure substance formed from the chemical combination of two or more different elements.
a substance that is formed in a chemical reaction is called a product=)After a chemical reaction, new chemicals are formed. For an example:-NaOH + HCl = NaCl + HOH(H2O)Chemical substances are formed in chemical reactions.
What is an atom
It depends upon nature of substances for example when Glucose or Salt are dissolved in water no new substance is formed so these are physical changes but when Ammonia gas is dissolved in water Ammonium and hydroxide ions are formed so it is a chemical change.
a compound is formed i guess that answers question rewrite many different substances can be formed from different chemical reactions Add: Products are formed from a chemical reaction.
