Answer:

pH = 14 - pOH

pH = -log[H+]

pH = pKa + log [A-]/[HA]

Explanation:

The equation used depends on what is given in the equation.

Which process moves molecules and has these traits?
Ostrovityanka [42]
Diffusion is the right answer, because technically the only acceptable answers here are diffusion and osmosis. But osmosis occurs in a semi-membrane, leaving no choice but diffusion.

a gas cylinder contains 2.0 mol of gas X and 6.0 mol of gas Y at a total pressute of 2.1 atm. what is he partial pressure of gas
Igoryamba

The answer is 1.6 atm. Let's first calculate the mole fraction of gas Y.

The mole fraction (x) is: x = n1/n, where n1 is a number of moles of an

individual gas in a mixture and n is total moles of the gas mixture. We

know that n1 of gas Y is 6.0 mol (n1 = 6.0 mol) and that there are in

total 8. mol of the gas mixture (n = 2.0 + 6.0 = 8.0 mol). Now calculate

the mole fraction of gas Y. x = 6.0/8.0 = 0.75. Now, let's use the mole

fraction of gas Y (x) and the total pressure (P) to calculate the

partial pressure of gas Y (P1): x = P1/P. P1 = x * P. If x = 0.75 and P =

2.1 atm, then the partial pressure of gas Y is: P1 = 0.75 * 2.1 atm =

1.6 atm.
