Acetone (C3H6O) is a liquid that is used to dissolve substances that do not mix with water. The boiling point of acetone is 56°C. If you have some gaseous acetone at 100°C and you cool it down, at what temperature in degrees C, will it start to condense? JUST give a number, no units)

Answer : Acetone start to condense below 56 °C

Explanation :

Boiling point : It is defined as the temperature at which vapor pressure of the liquid is equal to the atmospheric pressure of the liquid.

That means, the temperature at which the liquid changes into gas.

Condensation point : It is defined as the temperature at which the phase changes from a gaseous to liquid.

As per question, the boiling point of acetone is 56 °C. As, the gas is at 100 °C then the condensation of acetone will take place at 56 °C but below this temperature acetone exists in a liquid phase.

Hence, below 56 °C acetone start to condense.

u i forgot the answer?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
