Answer:

The sugar crystals recrystallises, and settles at the bottom of the container especially if the temperature of the mixture cools down gradually with time when left undisturbed.

Explanation:

Solubility is the ability of some solids (solute) to dissolve in a liquid (solute) forming a solution. It depends on temperature, amount of solute to solvent etc.

In some cases, leaving the product undisturbed over time can revert the process, forcing the solid to recrystallise out of the solvent.

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

CaCl2<br> Ca +<br> CI2<br> Balance this equation

Elis [28]

To balance Ca + Cl2 = CaCl2 you'll need to be sure to count all of atoms on each side of the chemical equation.

Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Calcium + Chlorine gas.
