Hydrogen bond</h3>
Hydrogen bonding is an electrostatic force of attraction between a hydrogen atom found between a pair of other atoms having a high affinity for electrons.
Hydrogen bonds cause water to be exceptionally attracted to each other creating cohesion.

Answer:
The answer to your question is pH = 9.2; [OH] = 1.58 x 10⁻⁵
Explanation:
Data
[H⁺] = 6.0 x 10⁻¹⁰ M
pH = ?
pH definition. pH measures the hydrogen concentration. pH measures the acidity and the alkalinity of a solution. A solution is acid if the pH goes from 0 to 6.9, a neutral solution has a pH of 7 and an alkali solution has a pH from 7.1 to 14.
pOH measures the [OH⁻] concentration
Formula
pH = -log[H⁺]
pH + pOH = 14
-Substitution
pH = -log[6 x 10⁻¹⁰]
-Simplification
pH = - (-9.2)
pH = 9.2
-Calculate pOH
pOH = 14 - pH
pOH = 14 - 9.2
pOH = 4.8
-Calculate the concentration of OH⁻
pOH = -log[OH⁻]
[OH⁻] = -antilog4.8
[OH] = 1.58 x 10⁻⁵
Answer:
The answer to your question is: 79.6 L
Explanation:
Data:
n = 60 moles
Pressure = P = 20.0 atm
Temperature = T = 50°C
Volume = V = ?
Convert temperature to Kelvin
°K = 273 + 50
°K = 323
Formula (ideal gas law)
PV = nRT solve for V
V = nRT / P
V = (60)(0.08206)(323) / 20 Substitution
V = 1590.32 /20
V = 79.6 L
