Explanation:
When copper chloride is added to water, it dissolves into the water since it is fairly soluble in water. The resulting mixture would be a solution. A solution is an example of a homogeneous mixture where it consists of a solute and a solvent. A homogeneous mixture is a type of mixture where the composition is uniform all throughout the system resulting to uniform properties as well. The opposite case is called an heterogeneous mixture where it consists of several components that are not uniformly distributed. Any point in this mixture would have different composition resulting to different properties in the mixture.
The force which acts on an object without coming physically in contact with it is called non-contract force. The most familiar example of a non-contract force is weight. In contrast, a contact force is a force applied to a body by another body that is in contact with it.
