Two compounds combine to form a new compound. When two substances react to form one new substance, it is a synthesis reaction.
The reactants are compounds that react to form new compounds (the products). apex
Same. Mass is not changed.
A combination of two substances that do not chemically react can be a mixture or a solution.When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.
A chemical reaction is the change that takes place when different substances react with one another to form new substances. The substances that react in a chemical reaction are called the reactants and the new substances formed are called the products.

substances
Two or more substances which can chemically react form new chemicals after the reaction.1. If these chemicals react they form new compounds.2. Without a chemical reaction they form a mixture.Read more: What_is_two_or_more_substance_are_combined
The word 'react' in chemistry means the interaction of substances to form new substances. It has nothing to do with density. Density is measured for a substance that is NOT undergoing a reaction.

A chemical change.
metallic
elements can combine to form new substances with different properties.
a chemical change
both :P the elements and compounds in the original substances will join together to form a new substance, with possible elements left over i.e. oxygen+glucose --> carbon dioxide+water (respiration)
