Question

calculati masa de metan care se formeaza prin reactia cu oxigenul a 320 kg carbune ce are un continut de 75% carbon

Answer 1

C + 2 H2 = CH4
%C = mC/m cărbune * 100
mC = 320*75/100 = 240 kg C
M C = 12 g/mol
M CH4 = 16 g/mol
12 g C................16 g CH4
240 kg C........................x
x = 320 kg CH4
