Answer 1

100 g cărbune.......60 g  carbon
1 tonă cărbune.................x
x = 0,6 tone carbon = 600 kg carbon
M C = 12 g/mol
12 g C........1 mol C
600 kg C...............y
y = 50 kmoli C
C + O2 = CO2 + 393 kJ
1 mol C........1 mol CO2
50 kmoli C.............z
z = 50 kmoli CO2
1 mol CO2........393 kJ
50 kmoli CO2...........a
a = 19650 MJ = 19650000 kJ
