The heat required to convert water is given as the product of the mas and the latent heat. 28.34 kJ heat must be removed from the water to change it into ice.
<h3>What is heat energy?</h3>
Heat energy is the product of mass, specific heat capacity, and temperature change. It is given as,

Given,
Mass of water = 456 gm
Specific heat capacity = 4.186 J / g K
Temperatutre change = 14.85 K
Substituting values above:

Therefore, 28.34 kJ of heat energy should be removed from the water.

Answer:
2FeBr3 + 3Na2S ➡️ Fe2S3 + 6NaBr
Answer:
6.76 moles.
Explanation:
2CO(g)+O2 (g) =2CO2(g)
When 2 CO mols were reacted with excess O2 then 2 mols of CO2 is created.
Therefore if 6.76 moles reacted, same number of CO2 will be created.
