Yes it does. There are eight grand of oxygen for every gram of hydrogen.
Yes, fluorite has a definite chemical composition: it is a calcium fluoride mineral with the chemical formula CaF2.
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.
Yes, compounds have a definite chemical composition. This means they are made up of a specific ratio of elements that are bonded together in a fixed arrangement. This composition can be represented by a chemical formula.
The chemical composition of water, H2O, remains the same because it is a pure substance with a fixed ratio of hydrogen to oxygen atoms. Water molecules consist of two hydrogen atoms covalently bonded to one oxygen atom, and this arrangement is stable and does not change under normal conditions.
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.
A material with definite properties and definite chemical composition is called a pure substance.
Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
Yes, fluorite has a definite chemical composition: it is a calcium fluoride mineral with the chemical formula CaF2.
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.
Yes
yes it can
A definite chemical composition
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.
Colon is an organ not a compound with definite composition.
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.
