Question

difference between

1. homogeneous and heterogeneous
2. element and compound
3. pure and impure substances ​

Answer 1

Answer:

Explanation:

homogeneous and heterogeneous

The terms heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree to which the materials are mixed together and the uniformity of their composition. ... There is only one phase of matter observed in a homogeneous mixture

element and compound

A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. ... A compound can be separated into simpler substances by chemical methods/reactions.

pure and impure substances

whereas an impure substance have two or more than two particle! A pure element or compound contains only one substance, with no other substances mixed in. Impure materials may be mixtures of elements, mixtures of compounds, or mixtures of elements and compounds.

Answer 2

Homogenous and heterogeneous:

A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneousmixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.

Element and compound:

A compound contains atoms of differentelements chemically combined togetherin a fixed ratio. An element is a pure chemical substance made of same type of atom. ... A compound can be separated into simpler substances by chemical methods/reactions.

Pure and impure substances:

an impure substance have two or more than two particle! A pureelement or compound contains only onesubstance, with no other substancesmixed in. Impure materials may be mixtures of elements, mixtures of compounds, or mixtures of elements and compounds.
