Kw = 1.219x10⁻¹⁴

kw = [H⁺] x [OH⁻]

in water [H⁺] = [OH⁻] therefore:

[H⁺] = √ kw

[H⁺] = √ <span>1.219x10⁻¹⁴

[H</span>⁺] = 1.104x10⁻⁷

pH = - log [H⁺]

pH = - log [ <span>1.104x10⁻⁷ ]

pH = 6.95

hope this helps!</span>

At high pressures how does the volume of a real gas compare with the volume of an ideal gas under the same conditions and why
malfutka [58]
Answer: No, a<span>t high pressures, volume of a real gas does not  compare with the volume of an ideal gas under the same conditions.

Reason: 
For an ideal gas, there should not be any intermolecular forces of interaction. However, for real gases there are intermolecular forces of interaction like dipole-dipole and dipole-induced dipole. Further, at high pressures, molecules are close by. Hence, extend of these intermolecular forces is expected to be high. This results in decreases in volume of real gas. Thus, </span>volume of a real gas does not  compare with the volume of an ideal gas under the same conditions.

The number of particles in 1 mole of hydrogen gas is ________.
ivanzaharov [21]
Hidrogen gas is a diatomic gas, this is H2, which means that one molecule of gas has two atoms (every molecule of hydrogen gas consists in H2).

The particles in gases are the molecules, not atoms.

So, every molecule is a particle, and when you are told that you have 1 mole of hygrogen gas means that you have 1 mole of H2 molecules which is the same that 1 mole of particles.

Therefore, the answer is one mole.

atroni [7]
Particle      mass                          charge                     location

protons     1.673*10 ^ - 27 kg        1.6*10 ^ -19 C        in the nucleus
neutrons   1.675*10 ^ - 27 kg        0                             in the nucleus
electron     9.11 * 10 ^ - 31 kg       -1.6 * 10 ^ - 19 C    around the nucleus (orbitals)

Protons and neutrons have almost same masses. Mass of electrons is 1/1840 the mass of the protons.

Protons and electrons have the same magnitud of charge with different sign. Protons are positive and electrons are negative. Neutrons do not have charge.
