What is the mass of CO2 if alll the coal undergoes combustion?
Railroad car holds 100 US tons of coal, assuing its anthracte coal, then its 90% by ass carbon. So far i got the combustion equation set up, athough im not sure its right. And how are these 2 amounts of CO2 compare??
C+2O2g—–> CO2 + 2H2Og
Easy 
:
Dry anthracite with the following composition by mass:
C 90%; H 3%; O 2%; N 1%; S 1%; ash 3%
Combustion equation for coal:
C + O2 => CO2 (12 kg C)+(32 kg O) => (44 kg CO2)
So 1kg C gives 11/3=3.67 kg CO2 by mass,
Hope u can work it out now ^^
Btw all equations for coal r written seperately hun..
Combustion equation for coal:
C + O2 => CO2 (12 kg C)+(32 kg O) => (44 kg CO2)
Combustion equation for hydrogen:
2 H2 + O2 => 2 H2O (4 kg H)+(32 kg O) => (36 kg H2O)
Combustion equation for sulphur:
S + O2 => SO2 (32 kg S) + (32 kg O) => (64 kg SO2)
