<h3>Solution:</h3>
  • According to law of conservation of matter, mass of reactants = mass of product formed.
  • Here, mass of hydrogen = 30 grams
  • Mass of oxygen = 30 grams
  • Hydrogen + Oxygen = Dihydrogen monoxide
  • Therefore, Mass of hydrogen + Mass of oxygen = Mass of Dihydrogen Monoxide
  • So, 30 grams + 30 grams = 60 grams.
  • So, 60 grams of dihydrogen monoxide is present in the product.
<h3>Answer:</h3>

A. 60 grams

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.
