I would say that Niven would have to calculate the atomic weights of Mg and O and then the total weight of MgO to get the percent of oxygen and then that way get a proportionate amount of the 28 grams of oxygen required to bond with the Mg and then add together the weight of Mg which would be 28.0 grams plus the weight of oxygen.

The particles in solids are not free to move because of strong attractive forces while gases are in constant random motion.
<h3>What is the nature of solids and gases?</h3>
Solids are composed of particles which are arranged in a definite pattern.
The forces of attraction between the particles are strong and the particles are not free to move.
Solids have definite volume and shapes.
Gases are composed of particles which are in constant random motion and whose forces of attraction between the particles are weak.
Therefore, the particles in solids are not free to move because of strong attractive forces while gases are in constant random motion.

The correct answer is HCl and CaCl₂
This happens in the following equation:
Ca(OH)₂₍s₎ + 2HCl₍aq₎ ⇒ CaCl₂₍aq₎ +2 H₂O₍l₎
The reaction is between a strong base and a strong acid thus neutralization is complete. calcium chloride (CaCl₂) is the salt while hydrochloric acid (HCl) is the acid.
