2.Compounds
3.Heterogeneous mixture​

Answer 1

${\huge{\pink{↬}}} \:  \: {\huge{\underline{\boxed{\bf{\pink{Answer}}}}}}$

1.) ELEMENT:- In chemistry, an element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei. Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by chemical means.

2.)Compunds:- In chemistry, a compound is a substance that results from a combination of two or more different chemical element s, in such a way that the atom s of the different elements are held together by chemical bonds that are difficult to break. ... The smallest unbreakable unit of a compound is called a molecule .

3.)Heterogeneous mixture:- A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. ... A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase.

Answer 2

Answer:

hope it helps you

Explanation:

An element is a pure substance that cannot be broken down by any physical or chemical means into simpler substances.

A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds.

A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
