This chemical process is called hydration.
hydration
When two or more materials combine chemically, they from a substance. When two or more materials combine and they do not react with each other, they form a mixture.
No. The two chemicals have different temperatures, and different operation pressures. They also have different rates of evaporation, and require different drying chemicals in the accumulator/drier. R134a will dissolve R12 (freon) drying chemicals, resulting in damage to the system. R12 can be recovered by some shops certified for work with the chemical, but the pressures of R134a are far higher for operation, and in some cases require replacement parts on the condensor and evaporator, and potentially on the pump. (the accumulator has to be replaced in any case, but again, different chemicals required). The lubricant oil in the pump as well, has a different breakdown under R134, and requires replacement refrigerant oil.
When you combine neutrons and protons you get an atomic nucleus.
Crir
Beryllium (Be) will combine in a 1-1 ratio with elements from group 16. It will combine in a 1-2 ratio with elements from group 17 (the halogens.) It will combine in a 3-2 ratio with elements from group 15. Examples: beryllium oxide - BeO; beryllium chloride - BeCl2; beryllium nitride - Be3N2.
Minerals in Rocks combine with Chemicals in the air,Chemical Weathering takes place.
Hydration
The ability to combine chemically through the formation of chemical bonds with another substance is a chemical property.
Many chemical elements combine with oxygen; the reaction with oxygen is called oxydation.
Water
The ability to combine with another substance is a chemical change. This is because once the substance is made it can not be taken out.
a chemical bond
A molecule
The ability to combine chemically through the formation of chemical bonds with another substance is a chemical property.
well physical weathering is when it breaks down rocks and chemical weathering is when rocks are dissolved or loosened so i suppose that it would be that over a certain amount of time goes by, the more weathering occurs. i hope that answers your question! (:
When atoms of two different elements join together (or combine) to make molecules of a compound, scientists say that a Chemical Change or Chemical Reaction has taken place. I you look at the substances you start off with and the substance you get after the change, they are often different.
This is called synthesis, a combination chemical reaction that changes the chemical bonds in the substances.
