Answer: Concentration of the chemist's sodium chloride solution is 34.4 mol/L.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n= moles of solute
= volume of solution in ml
Given : moles of 
= 6.89
volume of solution = 200 ml
Putting in the values we get:
Thus the concentration of the chemist's sodium chloride solution is 34.4 mol/L.
The word problem format to the task given above is: When magnesium reacts with steam, it produces magnesium hydroxide and liberate hydrogen gas.
<h3>How magnesium hydroxide is formed?</h3>
It happens that magnesium is an alkali earth metal and react with water in the gaseous state to librate hydrogen gas, when this reaction occurs, it results in the formation of magnesium hydroxide.
The chemical equation between magnesium and water is given below:
Mg + 2H₂O -----> Mg (OH)₂ + H₂
So therefore, we can accurately deduced that magnesium hydroxide is produced when magnesium is disolved in water.

Two alkaline earth metals; Be and Mg exhibit a diagonal relationship. The pair of elements are Be-Al and Mg-Li is Be-Al and Mg-Li.
Six elements make up the majority of alkaline earth metals (Group 2): beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). Compared to the elements in Group 1, this group typically contains smooth, silver metals with a less metallic character. Heavy metals like Ca, Sr, Ba, and Ra are equally as reactive as Alkali Metals Group 1 despite sharing many characteristics with that group. All elements found in alkaline earth metals contain two electrons in their valence shells, giving them an oxidation state of +2. This makes it possible for metals to shed electrons with ease, allowing them to create compounds with more stable ionic connections.

Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object. Such energy transfer can occur in three ways: radiation, conduction, and convection.
