Explanation:

It is known that number of moles of a substance equal to mass divided by its molar mass.

Mathematically,         No. of moles = \frac{mass}{\text{molar mass}}

It is given that no. of oles present are 27.2 mol and molar mass of N is 14 g/mol.

Therefore, calculate mass of N as follows.

                 No. of moles = \frac{mass}{\text{molar mass}}

                       27.2 mol = \frac{mass}{14 g/mol}

                      mass = 380.8 g

Thus, we can conclude that mass of N is 380.8 g.

Question 1 of 10
Alina [70]

D. The total number of gas molecules will decrease.

Explanation:

According to Le Chatelier's principle, an increase in pressure in a system involving gases will cause the total number of gas molecules to decrease.

Le Chatelier's principle states that "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

In a reaction involving gases, a change in pressure affects only reactions in a gaseous phase.

An increase in pressure on an equilibrium system will shift the position of the equilibrium to the side having smaller volume and vice versa.

Volcano help! *I GIVE THANKS!*
Pani-rosa [81]
A volcanic <em>eruption</em> occurs when the <em>pressure </em> in a magma <em>chamber</em> becomes so great it is released like a valve. Magma is released through the volcano's <em>cone</em> in an eruption of <em>lava</em> rocks (bombs) and ash. A volcanic <em>cone</em> develops over centuries as flowing <em>lava</em> from the active volcano <em>cools </em>to form layers of rock.

Recall rem = rad x q radiation weighting factor (q): the ability to transfer energy to the body 1 for photons 1 for electrons 2
tino4ka555 [31]

The biological risk for the first person than the second as a result of radiation weighting is 10 times.

<h3>What is radiation weighting factor?</h3>

As stated in the question, radiation weighting factor (q) is the ability to transfer energy to the body.

If radiation factor of proton = 2, and radiation factor of alpha particles = 20.

  • First person is exposed to alpha radiation = 20
  • Second person is exposed to protons = 2

Risk of first person with respect to second person = 20/2 = 10 times higher
