Answer:
pH = 14 - pOH = 14 - 6.907 = 7.903
=> [H₃O⁺] = 10^-pH = 10^-7.903 = 1.25 x 10⁻⁸M
Explanation:
Some measure of examining information
This is false, a compound does not have to contain both cations and anions if ions are present.
Answer:
the freezeng point of solution is -12°c b/c it dencity is 0.854 formula =
Answer:
The partial pressure of oxygen is 52 kPa.
Explanation:
We apply Dalton's law, according to which the sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of this:
Ptotal = P N2 + P C02 + P 02
300 kPa= 200kPa + 48 kPa + P 02
P 02= 300 kPa - 200kPa - 48 kPa= <em>52 kPa</em>
