<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)
Answer:
Chlorine fluoride is expected to have the lowest boiling point.
Explanation:
<em>Interhalogens</em> have covalent bonds, and as such,<u> the higher the difference in electronegativity, the higher the expected boiling point will be</u>.
Looking at the Periodic Table of elements, we can see that in these four examples, <em>the compound with the lowest electronegativity difference</em> -and thus<em> the lowest boiling point</em>-, is chlorine fluoride, ClF.
Answer:
The older scientist were ignorant
Explanation:
the older scientist were ignorant to think that younger is worse
Answer: The molality of solution is 0.66 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in g
moles of 
= 
Now put all the given values in the formula of molality, we get
Therefore, the molality of solution is 0.66 mole/kg
Luminescent I'm pretty sure :)
