1.A freshly squeezed orange juice is a homogeneous mixture because it is made of only one kind of fruit. Sugar water is an example of a pure substance. A mixture is when two or more substances undergo a chemical reaction to give new substances.

2.They cannot get separated into other forms of matter. Elements and compounds are the two categories to classify pure substances further. When two or more pure substances come together, we call it a mixture.

3.Pure substance because Elements cannot be separated into other types of matter (physically or chemically).

4.Steel is considered a mixture rather than a compound because the iron does not chemically bond with the carbon and other components. Instead, in simple iron-carbon alloys, the carbon atoms are small enough to intersperse themselves within the open spaces of the iron crystal. Steel is a mixture.

5.Sugar is a pure substance because its composition is homogeneous throughout. Pure substances can be either elements or compounds. Sugar or sucrose is a compound with the chemical formula C12H22O11.
