2.2311 moles of gas are there in a 50. 0 l container at 22. 0 °c and 825 torrs.
<h3>What is an ideal gas?</h3>
An Ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.
Assuming the gas is ideal, we can solve this problem by using the following equation:
PV = nRT
Where:
P = 825 torr ⇒ 825 / 760 = 1.08 atm
V = 50 L
n = ?
R = 0.082 atm·L·mol⁻¹·K⁻¹
T = 22 °C ⇒ 22 + 273.16 = 295.16 K
We input the data:
1.08 atm x 50 L = n x 0.082 atm·L·mol⁻¹·K⁻¹ x 295.16 K
And solve for n:
24.20312
n = 2.2311 mol
Hence, 2.2311 moles of gas are there in a 50. 0 L container at 22. 0 °c and 825 torrs.

Answer:
Decreasing temperature.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
- The choices here:
1) Decreasing concentration of SO₂,
The concentration of SO₂ decreases, so the reaction will be shifted to the left direction to suppress the decrease in SO₂ concentration.
2) Decreasing temperature,
ΔH= – 98.8 kJ/mol, the negative sign means that the reaction is exothermic and release the heat.
If the temperature decreased, this means that the products decrease, so the reaction will shift to the right to suppress the decrease in temperature.
<em>It is the right choice.</em>
3) Increasing concentration of SO₃:
Increasing concentration of SO₃ will shift the reaction to the left to suppress the effect of increasing the concentration of SO₃.
4) Increasing volume:
Increasing the volume will decrease the pressure.
Decreasing the pressure will shift the reaction of gases to the side of higher no. of moles (left side).
- <em>So, the right choice is: Decreasing temperature.</em>

<span>All acids form their conjugate base and a proton or H+ in an aqueous solution, in water. Since formic acid is an acid, although a weak electrolyte, it will react with water to form the conjugate base HCOO with a negative 1 charge. The other solute will be the proton H+, also written as hydronium H3O+.</span>
For a tragedy of the commons to occur a resource must be scarce, rivalrous in consumption, and non-excludable. Solutions to the tragedy of the commons include the imposition of private property rights, government regulation, or the development of a collective action arrangement.
