Question

Calculate the heat (in calories) released when 115 g of CHCl3 changes from a liquid to a solid at

its freezing point.

Answer 1

Answer: 8855 Joules energy is released when 115 g of
`CHCl_3` changes from a liquid to a solid at its freezing point.

Step-by-step explanation:

Latent heat of freezing is the amount of heat released to convert 1 mole of liquid to solid at atmospheric pressure.

Amount of heat released to freeze 1 gram of
`CHCl_3` = 77 J/g

Mass of
`CHCl_3` given = 115 gram

Heat released when 1 g of
`CHCl_3` is freezed = 77 J

Thus Heat released when 115 g of
`CHCl_3` is freezed =
`(77)/(1)* 115=8855J`

Thus 8855 Joules energy is released when 115 g of
`CHCl_3` changes from a liquid to a solid at its freezing point.
