Answer:

CHCL3= 11.73 mL

CHBr3= 8.268 mL

Explanation:

Let x be the mL of CHCl3 and y be the mL of CHBr3, then we have:

y+x = 20 mL

1.492x+2.89y=2.07* 20.0 mL

If the molar heat of fusion of water is 6.01
Zolol [24]

Answer : The heat energy required to melt 2 kg of ice was, 667.7 kJ

Explanation :

First we have to calculate the moles of ice.

\text{Moles of ice}=\frac{\text{Given mass ice}}{\text{Molar mass ice}}=\frac{2kg}{18g/mol}=\frac{2000g}{18g/mol}=111.1mol

Now we have to calculate the heat energy.

As, heat energy required to melt 1 mole of ice = 6.01 kJ

So, heat energy required to melt 111.1 mole of ice = 111.1 × 6.01 kJ

                                                                                  = 667.7 kJ

Therefore, the heat energy required to melt 2 kg of ice was, 667.7 kJ
