Answer:
2
Explanation:
It is going through the air and is moving so that means that it has kinetic energy. But it is also going to go the down, which gives it potential energy.
Explanation:
Molar mass of
is 114.23 g/mol. Therefore, its number of moles are calculated as follows.
No. of moles =
= ![\frac{5 g}{114.23 g/mol}](https://tex.z-dn.net/?f=%5Cfrac%7B5%20g%7D%7B114.23%20g%2Fmol%7D)
= 0.043 mol
So, 0.043 moles are releasing 239.5 kcal of heat. Hence, heat released by 1.54 mol will be calculated as follows.
![\frac{239.5 kcal}{0.043 mol} \times 1.54 mol](https://tex.z-dn.net/?f=%5Cfrac%7B239.5%20kcal%7D%7B0.043%20mol%7D%20%5Ctimes%201.54%20mol)
= 8577.44 kcal
Thus, we can conclude that 8577.44 kcal heat is released by the combustion of 1.54 mol of
.
