Give reason water is a compound and not a mixture?
Water is a compound because it is made up of two different elements, hydrogen and oxygen, chemically bonded together in a fixed ratio (H2O). A mixture, on the other hand, is a physical combination of two or more substances that are not chemically bonded and can be separated by physical means.
Why are elements and compounds are pure substances and homogeneous mixture are not?
Well, elements and compounds are pure substances. This is because the atoms in an elements are of one type only. Thus making it pure. But in a compound, the ratio of the masses of the combining elements or compounds are fixed. For example, the ratio for hydrogen and oxygen to combine together to form water is 1:8. Therefore the compound is also a pure substance. But homogenous mixtures are not pure substances as the components can be mixed in any ratio. We can make brine solution by mixing any amount of salt and water. There is no fixed ratio. So homogenous mixtures are not pure.
Do you simplify empirical formula ratios?
Yes, empirical formulas provide the simplest ratio of elements in a compound. By determining the molar ratios between different elements in a compound, we can find the simplest whole number ratio that represents the elements present.
What is a substance formed from two or more elements form when chemically combined in a set ratio?
A compound is a chemical combination of two or more elements in a fixed ratio.
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance it is an?
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance, it is a compound. A compound is a substance composed of two or more elements chemically bonded together in a fixed ratio.
