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.

It is the first option bc if it absorbed heat it it will pressurize and could explode.
the 1st one is balanced, the 2nd isn't (the number of Mg differs from left 1 to right 2).
The third is also not balanced, 2 F left,2*3=6 on the right
