When 0.5mol of a certain ionic substance is dissolved in 1.0kg of water, the freezing point of the resulting solution is -1.86 ∘c.(freezing point depression of water is -1.86 how many ions does the substance give when it dissolves

2 mole of ion are dissolved in this solution

Explanation:

Coligative property for Freezing point depression.

The formula is this:

ΔT = Kf. m . i

How many ions does the substance give when it dissolves. This question is asking for the i value.

0° - (-1.86°C) = 1.86 °C / m . 0.5m . i

1.86 °C  / 1.86 °C /m . 0.5 m= i

2= i

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
