Metal oxides M2O, peroxide M2O2, and superoxide MO are produced by alkali metals. Metal oxide is also referred to as basic oxide since basic hydroxide is the end result of interactions between metal oxide and water. As a result, their combination with acid produces salt and water in a manner similar to a regular acid-base reaction.
One of the most significant and well-characterized solid catalysts is metal oxide. Metal oxides are used in acid-base and redox processes and are regarded as heterogeneous catalysts.
Several metals are separated from their naturally occurring compounds like oxide and chloride using a breakdown reaction.
Metal oxides are crucial in various additional applications, such as energy production, conversion, and storage, as well as in environmental remediation and pollution monitoring.
Because they react with weak acids to produce salt and water, metallic oxides are basic in nature. They further react with water to create metal hydroxides, which are naturally alkaline due to the production of OH- ions in solution.
Thus, Metal oxides M2O, peroxide M2O2, and superoxide MO are produced by alkali metals.

Answer:
This question is incomplete
Explanation:
A solution is an homogeneous mixture of two or more substances. These substances could be in the same form (as in solid, liquid or gas) or in different forms. Examples of solution in the same phases are
Examples of solution in different phases are
NOTE: Homogeneous mixture is a mixture whose constituents are evenly distributed in the mixture
A solution has a number of unique characteristics. First of all, it has a consistent composition throughout, which denotes that the solute is dispersed uniformly throughout the solvent to produce a homogenous mixture.
Second, the solution is transparent and not turbid because the solute particles do not scatter light. Thirdly, a solution doesn't have discrete layers since the solute has completely dissolved in the solvent. Furthermore, the presence of the solute particles causes the boiling point of the solution to normally be higher than that of the pure solvent. However, because the volume change during dissolution is typically minimal, the density of the solution stays almost the same as that of the pure solvent.
