<h2>Answer:</h2>
Net energy of reaction = -5412kJ
Reaction is exothermic
<h2>Explanations:</h2>
Given the following reaction;
The net energy of the reaction is expressed as:
Determine the enthalpy change of the product
Determine the enthalpy change for the reactant
Determine the net energy for the reaction
Since the net energy of the reaction is negative, hence the reaction will be exothermic (energy is liberated to the surrounding)

Explanation:
Did u find the answer !! It's on
my daughters homework !! I can't find it neither
To be floating, the gravity force of the iceberg should be same as the buoyancy force that result from the difference of the ice and water density.
The density of ice is 920 and water is 1030, then the difference should be: 1030kg/m3-920kg/m3= 110kg/m3
Let say that the volume of ice below the water is volume1 and the volume above the water(exposed volume) is volume2.
You can get this equation
volume1+volume2= 100%
volume1= 100%- volume2
Insert it into the buoyancy and gravity force will result
buoyancy=gravity
110kg/m3*volume1= 920kg/m3 *volume2
110kg/m3*(100%- volume2)= 920kg/m3 *volume2
110kg/m3 - 110kg/m3*volume2= 920kg/m3 *volume2
110kg/m3 = 1030kg/m3 *volume2
volume2= 110/1030= 0.1067= 10.7%
