Calculate the amount of heat required to completely sublime 40.0 g of solid dry ice (co2) at its sublimation temperature. the heat of sublimation for carbon dioxide is 32.3 kj/mol.

The amount of heat required for the sublimation of 40.0 g of solid dry ice CO₂ is 29.3 kJ.

One mole of CO₂ has a mass of 44.0095 g.

Calculate the number of moles  n in 40.0 g of CO₂ .

Heat of sublimation is the amount of heat required by 1 mole of a substance to convert itself from solid state to a vapor state at constant temperature and pressure.

1 mole of CO₂ requires 32.3 kJ of energy to sublimate.

Therefore, the heat required to sublimate 0.9089 mol of CO₂ is given by,

Thus, the heat required to sublimate 40.0 g of CO₂ is 29.3 kJ.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
