Answer:
V = 177.4 L.
Explanation:
Hello there!
In this case, since this gas can be assumed as ideal due to the given data, we can use the following equation:

Thus, by solving for volume we obtain:

So we can plug in the temperature in Kelvins (537 K), the pressure in atmospheres (0.404 atm) and the molar mass (54 g/mol) to obtain:

Best regards!
Answer:
C.
Explanation:
A. C - 6 electrons - 1s2 2s2 2p2
B. O - 8 electrons - 1s2 2s2 2p4
C. N - 7 electrons - 1s2 2s2 2p3
D. Be - 4 electrons - 1s2 2s2
Option (C) is the correct answer.
In the chemical reaction, reactants are the starting elements or compounds which will chemically react and will form the products. Reactants are only present on the left hand side of the reaction and products are present on the right hand side of the reaction.
Reactants present in the reaction is completely used up in the reaction to form products implies no traces of reactants will be present in the product side.
For example:

Here, hydrogen and oxygen are the reactants whereas water is the product (new substance). Hydrogen reacts with oxygen and form water i.e. hydrogen and oxygen is completely used up in the reaction to form new substance i.e. water.
Hence, substances that are used up in a reaction is known as reactants of the reaction.

Answer:
pOH = 8.41
Explanation:
From the question given above, we obtained the following information:
Concentration of Hydrogen ion [H⁺] = 2.6×10¯⁶ M
pOH =?
Next, we shall determine the pH of the solution. This can be obtained as follow:
Concentration of Hydrogen ion [H⁺] = 2.6×10¯⁶ M
pH =?
pH = – Log [H⁺]
pH = – Log (2.6×10¯⁶)
pH = 5.59
Finally, we shall determine the pOH of the solution. This can be obtained as follow:
pH = 5.59
pOH =?
pH + pOH = 14
5.59 + pOH = 14
Collect like terms
pOH = 14 – 5.59
pOH = 8.41
Therefore, the pOH of the solution is 8.41
