Due to its higher oxygen content and based on its structure dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.
<h3>What is the calorific value of a fuel?</h3>
The calorific value of a fuel is the amount of heat energy released from the combustion of the fuel under standard conditions.
Dietheylene glycol, isopropanol and paraffin wax are all used as fuels.
However, due to it higher oxygen content and based on its structure, diethethylene glycol has a higher calorific value than either isopropanol or paraffin wax.
Therefore, dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.

There is 9.375 g of nitrogen. This is because when a half-life passes, the mass becomes 2 times less. Since two half-lives have passed, you need to divide by 4.
H2SO4
oxidation number of hydrogen :- +1
oxidation number of oxygen :- -2
if oxidation number of H2SO4 is x
2x (+1) + x + 4x (-2) = 0
+ 2 + x -8 = 0
x = +6
<u>oxidation number of H2SO4 :- +6</u>
Answer:

.
Explanation:
Hello,
In this case, for substantiating the substance having the lowest density we need to compute it in the same units for each case as shown below:
A) 
B) 
C) 
D) 
Therefore, the lowest density corresponds to C) A mass of 750 g and a volume of 70 dL
