While ionic compounds and polar molecules dissolve the best in water, nonpolar molecules do not. Example of a such nonpolar substance: oil. Oil forms clumps or beads in water because the nonpolar molescules are shoved together. Why? The water molecules are more attracted to each other than to the nonpolar molecules.
Substances that do not react easily are called inert, passive, or noble.
Noble metals include Platinum, Gold, Iridium. Inert gases are Argon Helium, Xenon, etc.
Passivated alloys can be Iron-nickel-chromium steels.
Organic materials include certain plastics and waxes. Minerals such as glass are fairly inert too.
Water is a polar molecule, and because of this, water dissolves other polar substances and many ionic substances. However, water does not dissolve nonpolar substances.
A catalyst is a substance that does not react or change in a chemical reaction but without it the chemical reaction could not occur.
This is how they react to the substances. Sometimes the substances that are inside the plant will react in an unusual way with the substance.

These substances are a combusible material and oxygen.
Combustible substance : Substances that burn easily or catch fire easily are called combustible substances. Paper, clothes, wood, LPG are all combustible substances. Without these substances, a fire cannot be started.
no
Sugar is easily oxidized, so almost any oxidizing substance reacts with sugar. Acids of oxidized nonmetals, especially, react easily with sugar.
Copper is not very reactive. It does not react easily with most substances, including many acids.
when two substances react a chemical change occurs
The ability to react with other substances is a chemical property.
