Answer:
3.66 tones
Explanation:
From the reaction , according to the question is as follows -
C + O₂ -----> CO₂ + heat
from the above reaction , It is clear , that -
1 mol of C reacts with 1 mol of O₂ to give , 1 mol of CO₂ .
Since ,
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
For the above equation ,
1 mol C , means , 12 gm of C ,
1 mol O₂ , means , 16 gm of O₂ ,
1 mol CO₂ , means , 44 gm of CO₂ ,
The simplest ratio , of the masses of C , CO₂ , is as follows -
12 : 44 = 3 : 11
Hence ,
By burning 1 ton of coal (Carbon) will produce = ( 1 * 11 / 3 ) tones of CO₂
= 3.66 tones
In case , the coal is pure , i.e. have only carbon , then the above reaction will follows and give the maximum yield , and as the content of carbon reduces , the amount CO₂ also reduces .
