When 16.4 g of steam at 100°C condenses how much heat is released?
OLEGan [10]

Answer:

37064 J

Explanation:

Data Given:

mass of Steam (m) = 16.4 g

heat released (Q) = ?

Solution:

This question is related to the latent heat of condensation.

Latent heat of condensation is the amount of heat released when water vapors condenses to liquid.

Formula used

            Q = m x Lc . . . . . (1)

where

Lc = specific latent heat of condensation

Latent heat of  vaporization of water is exactly equal to heat of condensation with - charge

So, Latent heat of  vaporization of water have a constant value

Latent heat of  vaporization of water = 2260 J/g

So

Latent heat of condensation of water will be = - 2260 J/g

Put values in eq. 1

          Q = (16.4 g) x (- 2260 J/g)

          Q = - 37064 J

So,  37064 J of heat will be released negative sign indicate release of energy

What will be the effect on the solubility of BaF2 if the following changes are made: increasing temperature; adding NaF; adding
borishaifa [10]

In BaF₂ the solubility will decreases on adding NaF

the solubility will increases on adding HCl

<h3>SOLUBILITY OF BARIUM FLUORIDE</h3>
  • Increase in temperature will increase the solubility of the solid.
  • By adding NaF - decrease the solubility of BaF₂
  • By adding HCl - increase the solubility of BaF₂

<h3>BARIUM FLUORIDE</h3>
  • It is colourless solid that occur as rare mineral
  • It is corroded by moisture
  • It is used in window of IR spectroscopy

Hence the barium fluoride the solubility decreases on adding NaF and increases on adding HCl.
