B Correct answer
Explanation

Bronze is a alloy, it is composed of the mixture of copper and tin. It was made before 3000 bc, though its use in artifacts did not become common until much later. The proportions of copper and tin varied widely (from 67 to 95 percent copper in surviving artifacts).

Salt, sugar, and many other substances dissolve in water to form :

  1. homogenous mixture

  2. heterogenous mixture

  3. Ionic compound

  4. molecular compound
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A mixture is a material system made up of two or more different substances which are mixed but are not combined chemically. A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures.

Which of the following is a homogeneous solution?

  1. Muddy water

  2. Bread

  3. Concrete

  4. A solution of sugar in water
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The solution in which the concentration of solute is the same in every part of the solution is known as a homogeneous solution, sugar is completely soluble in water and forms homogeneous solution.
