Question 1). Chemical reactions cannot be used for viewing any chemical reaction in a laboratory. Some chemical reactions require special conditions of temperature and pressure that cannot be reached in a laboratory, so they cannot be viewed in it.
Question 2) Magnesium is found in fresh water. The presence of magnesium ions (and calcium ions) in water is called hardness.
Question 3) The result fo a chemical reaction is called the product. For example, in the reaction H2 + O2 --> H2O, H2 and O2 are the reactants and H2O is the product.
