Answer:
3 In solution, the component that present in small amount is known as solute and the component present in larger amount known as solvent. Nine kinds of solution are possible.
4We have a word for substances that form solutions when they are mixed with water. These substances are called soluble substances. Substances that do NOT form solutions when they are mixed with water are called insoluble substances.
Answer:
(1) a way of solving a problem, dealing with a difficult situation, etc. is called solution.
TWO examples = Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture.
(2) We have a word for substances that form solutions when they are mixed with water. These substances are called soluble substances. Substances that do NOT form solutions when they are mixed with water are called insoluble substances.
(3) The main risks of drinking only distilled water are associated with the lack of dissolved minerals, such as magnesium and calcium. Some of the adverse effects of drinking just distilled or low mineral water include: a flat taste that many people find unappealing, leading to reduced water consumption.
