Answer:
4.3 moles of Fe2O3
Explanation:
The calculations are shown in the picture.
Formula= P4O6
You are going to want to flip the elements subscripts with one another.
P6O4
P will just stay as phosphorus, but since oxygen has 4 atoms, itbwill become tetroxide

Answer: is 1155 kJ
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done or by the system
w = work done by the system= {Work done on the system is positive as the final volume is lesser than initial volume}
w = (1kcal=4.184 kJ)
q = +1.1 MJ = 1100 kJ (1MJ=1000kJ) {Heat absorbed by the system is positive}
Thus is 1155 kJ
