Although all gases closely follow the ideal gas law PV = nRT under appropriate conditions, each gas is also a unique chemical substance consisting of molecular units that have definite masses. In this lesson we will see how these molecular masses affect the properties of gases that conform to the ideal gas law.
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.

Explanation:
Just remember the trends. From left to right, atomic radius decreases because proton increases and pulls electrons closer. From top to bottom, atomic radius increases because there are more electron shells.
