Explanation:
The given data is as follows.
mass = 0.158 g, volume = 100 ml
Molarity = 1.0 M, =
The given reaction is as follows.
So, moles of magnesium will be calculated as follows.
No. of moles =
=
=
= 0.0065 mol
Now, formula for heat released is as follows.
Q =
=
=
= 3010.32 J
Hence, heat of reaction will be calculated as follows.
=
= -4.63 J/mol
or, = (as 1 kJ = 1000 J)
Thus, we can conclude that heat of given reaction is kJ/mol.
Because of the fact that NaBr is an ionic bond, the bond is harder to break, therefore it needs more heat (or a higher temperature) to break it.
The answer would be C. Heatstroke because it is a condition by your body overheating
