Answer:

Electrons

Explanation:

Cathode rays carry electronic currents through the tube. Electrons were first discovered as the constituents of cathode rays. J.J. Thomson used the cathode ray tube to determine that atoms had small negatively charged particles inside of them, which he called “electrons.”

Does the reaction of a main-group metal oxide in water produce an acidic solution or a basic solution? Write a balanced equation

Fynjy0 [20]

<u>Answer:</u> The main group metal produce a basic solution in water and the reaction is $MO+H_2O\rightarrow M(OH)_2$

<u>Explanation:</u>

Main group elements are the elements that are present in s-block and p-block.

The metals that are the main group elements are located in Group IA, Group II A and Group III A.

Oxides are formed when a metal or a non-metal reacts with oxygen molecule. There are two types of oxides which are formed: Acidic oxides and basic oxides.

Acidic oxides are formed by the non-metals.
Basic oxides are formed by the metals.

When a metal oxide is reacted with water, it leads to the formation of a base.

The general formula of the oxide formed by Group II-A metals is 'MO'

The chemical equation for the reaction of metal oxide of Group II-A and water follows:

$MO+H_2O\rightarrow M(OH)_2$

Hence, the main group metal produce a basic solution in water and the reaction is $MO+H_2O\rightarrow M(OH)_2$
