Question

ce cantitate si masa de CO2 se vor elimina la arderea a 100 mol de carbon. ce masa de c a fost arsa

Answer 1

100moli ..........x moli
....C + O2 -> CO2
1..........................1
x=100×1/1=100 moli CO2
MCO2=Ac+2Ao
MCO2=12+2×16=44g/mol
n=m/M => m=n×M => m=44×100 => m=4400 g CO2
Mc=Ac=12
n=m/M => m=n×M => m=100×12 => m=1200 g C
