Yes it does. There are eight grand of oxygen for every gram of hydrogen.
Because water is a compound, a type of pure substance, which has a definite composition.
Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.
Fluorite is calcium difluoride - CaF2.
Law of definite proportion, sometimes also called the law of constant composition.
The law of definite proportions states that all chemical compounds have constant proportions of their components.
Because water is a compound, a type of pure substance, which has a definite composition.
Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
Atom
Yes
yes it can
A definite chemical composition
Colon is an organ not a compound with definite composition.
Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.
Items like H2O and CoC2 have a definite chemical composition, and require exact amount of particles to forma reaction. However; particles which are soluble in water do not have a definite chemical reaction.
Yes
This law hasn't a chemical equation !
It would depend on your definition of a chemical. A chemical is: "a substance produced by or used in a chemical process." And, water is a chemical because it is be used in chemical reactions such as neutralization, redox, etc. I believe what you're asking though is if water is a chemical substance: "a material with a definite chemical composition." Water is also a chemical composition because of its electron configuration in its valence shell which defines its chemical properties.
