I believe the strength comes from its ability to break the particle bond in the molecule. So the bond dissociation energy
All are the same elements but they differ in their atomic mass therefore this process will called Isotopes
Answer:
C. 26.4 kJ/mol
Explanation:
The Chen's rule for the calculation of heat of vaporization is shown below:
Where,
is the Heat of vaoprization (J/mol)
is the normal boiling point of the gas (K)
is the Critical temperature of the gas (K)
is the Critical pressure of the gas (bar)
R is the gas constant (8.314 J/Kmol)
For diethyl ether:
Applying the above equation to find heat of vaporization as:
The conversion of J into kJ is shown below:
1 J = 10⁻³ kJ
Thus,
<u>Option C is correct</u>
Answer:
the solid melted and gained energy
it also looks like some of the water evaporated
Explanation:
p.s. also the molecules expanded
In a reduction reaction,
some electrons are gained by the substance being reduced. The balanced
half-reaction to this would be:
<span>MnO2(s) + 4 H+ (aq)
+ 2e ---> Mn^2+ (aq) + 2 H2O
(aq)</span>
<span>It is called balanced reaction
since the number of each element in the left side is equal to the number of
each element on the right side.</span>
