Answer: the pressure exerted by the gas is 652 x 10^3 Pa, which corresponds to 652 kPa
Explanation:
The question requires us to calculate the pressure, in kPa, connsidering the following information:
<em>number of moles = n = 4.20mol</em>
<em>volume of gas = V = 15.0L</em>
<em>temperature of gas = T = 280.0 K</em>
We can use the equation of ideal gases to calculate the pressure of the gas, as shown by the rearranged equation below:
Since the volume was given in L and the question requires us to calculate the pressure in kPa, we can use R in units of L.Pa/K.mol:
<em>R = 8314.46 L.Pa/K.mol</em>
Applying the values given by the question to the rearranged equation above, we'll have:
Therefore, the pressure exerted by the gas is 652 x 10^3 Pa, which corresponds to 652 kPa.
The charge on the monatomic ions of Magnesium, Aluminum, Strontium, and Nitrogen are +2, +3, +2, and -3.
<h3>What is the charge on the ions of atoms of Magnesium, Aluminum, Strontium, Nitrogen?</h3>
The charge on an ion is due to the valency of the atom.
The charge on the ion shows the number of electrons gained or lost by the atom in order to form an ion.
The charge on an ion depends on the group the element belongs to.
Therefore, the charge on the monatomic ions of Magnesium, Aluminum, Strontium, and Nitrogen are +2, +3, +2, and -3.

Explanation:
If a freezer is not cold, maybe the condenser coils are dirty. You should clean these every 6-12 months. If not check the evaporator fan motor, it draws air over the evaporator coil and circulates it through the freezer. Your last option is to start relay, the start relay provides power to the compressor. Hope this helped!
