Answer:
moist air is less dense than dry air because water has a lower molecular weight than nitrogen and oxygen
Answer:
Water vapor is a relatively light gas when compared to diatomic Oxygen and diatomic Nitrogen. Thus, when water vapor increases, the amount of Oxygen and Nitrogen decrease per unit volume and thus density decreases because mass is decreasing.
The molar mass of magnesium nitride ) is 100.91 g/mol.
To calculate the molar mass, we need to add up the atomic masses of each atom in the molecule. The atomic masses of the elements in are:
Magnesium: 24.31 g/mol
Nitrogen: 14.01 g/mol
The molar mass ofmagnesium nitride is calculated as follows:
Molar mass of magnesium nitride = 3 * 24.31 g/mol + 2 * 14.01 g/mol
= 100.91 g/mol
Therefore, the molar mass of magnesium nitride is 100.91 g/mol.

Answer:
The reaction would be 1500n (equal reaction)
Explanation:
This can be explained by Newton's third law of motion which states that for every action (force), there is an opposite and equal reaction. In other words, when two objects or people come in contact, the magnitude of force which they exert on each other is equal and they both feel an equal reaction force.
It doesn't matter whether one of the colliding bodies is of bigger mass than the other. This Newton's third law of motion is also known as the law of action and reaction.
