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.

b. .Silver has a lower activity than hydrogen and cannot replace it
Explanation:
The reaction between silver and water cannot proceed because Ag has a lower activity than hydrogen in water.
H₂O + Ag → no reaction
- This reaction is referred to as as single displacement reaction.
- In this kind of reaction, one specie replaces another.
- The replacement of a metallic ion in solution by a metal atom higher in the activity series is the driving force for this reaction.
- Hydrogen is higher than silver and the activity series and will not be displaced by it.
- Therefore, no reaction will occur.
