Answer:
The correct answer is physical properties and/or phase properties.
Explanation:
Chemical properties can alter the substance (if you burn wood, it becomes ash and is no longer wood).
Reactive properties are also chemically changing the substance.
Phase properties are where the element can be in solid, liquid, or gas form so these could also be an answer.
Answer: The percent yield for the 
is, 86.7 %
Explanation : Given,
Moles of 
= 2.36 mol
Moles of = 6.14 mol
First we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 2 moles of react to give 6 moles of
So, 2.36 moles of react to give 
mole of
Now we have to calculate the percent yield for the .
Experimental yield = 6.14 moles
Theoretical yield = 7.08 moles
Now put all the given values in this formula, we get:
Therefore, the percent yield for the is, 86.7 %
Answer:
B
Explanation:
<h3><em>Liquid with a low specific heat
</em></h3>
Answer: Option c. Solution A has a lower boiling point than solution B
Explanation:
For solution A, i = 1 means the solution is a non-electrolyte. This clearly indicates that solution A contains covalently bonded compound. Covalently bonded compounds have lower boiling when compared to those of the ionic.
For solution B, i = 2 means the compound is an electrolyte and it forms two ions. From this result, it is very clear that the compound in solution A is an ionic compound. Ionic compounds have higher boiling points than covalent compounds
Therefore, solution A will have a lower boiling point than solution B
