Give reason water is a compound and not a mixture?
A compound is defined by a substance in which the elements that it is made of are in a fixed ratio. In this case the ratio between the hydrogen and oxygen in 2:1. A mixture is a substance in which the elements that make it are not in a fixed ratio
What is represented in the empirical formula of a compound?
The absolute ratio of the component elements.
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.
Which type of substance is composed of two or more different kinds of elements always in the same ratio?
Two or more different elements that are chemically combined in a definite ratio is a compound. Based on the nature of the bonds, it can be called an ionic compound (i.e. atoms bonded together by ionic bonds) or an molecular compound (i.e. atoms bonded together by covalent bonds).
Do you simplify empirical formula ratios?
Yes. An empirical formula is the simplest ratio of the elements in a compound.
Shows the ratio of elements in a compound?
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
