The volume occupied by one mole of any gas at standard temperature(0o) and pressure(1 atm) is 22.4 litres. This volume is a close approximation and different gases vary slightly. The molar volume of any gas at S.T.P. is 22.4L .The mole of any gas can therefore be found using the expression on the right.
Answer:
The answer is 4.
Explanation:
According to the first sentence of the paragraph an answer have to include H+ and OH- . That leaves 2 and 4. And 2 is not a balanced reaction since there are more moles on the right than the left. That leaves 4 as the only answer that shows the equilibrium that includes the OH and H+ and is balanced.
The answer is to your question is b.
Yes A is the correct answer hope this helped
