Answer:


Explanation:
Hello,
In this case, for the calculation of the temperature in degree Celsius we subtract 273.15 to the given temperature in kelvins:

Next, by applying the following equation we compute it in degree Fahrenheit:

Clearly, since the initial unit has two significant figures the computed units also show two significant figures.
Regards.
After some thinking I have come to the conclusion that the answer is C.
Answer:
Explanation:
Resonance structure occurs in an organic compound that undergoes resonance effects. This resonance effect is sometimes called the mesomeric effect helps to increases the stability of organic compounds that have alternating single bonds and double bonds.
The second resonance structure diagram for the ion given in the question can be found in the attached diagram below.
