Answer» 2 C6H6+15 O2=12 CO2+6 H2O Explanation: LET the variables p , q , r , s represent integers such that: XX p ⋅ C 6 H 6 + q ⋅ O 2 = r ⋅ C O 2 + s ⋅ H 2 O
Considering the ELEMENT C , we have: XX p ⋅ 6 = r ⋅ 1
XXXX → r = 6 p
Considering the element H , we have: XX p ⋅ 6 = s ⋅ 2
XXXX → s = 3 p
Considering the element O , we have: XX q ⋅ 2 = r ⋅ 2 + s ⋅ 1 = 12 p + 3 p = 15 p
XXXX → q = ( 15 2 ) p
The SMALLEST value of p > 0 for which q is an integer is: XX p = 2
XXXX → { q = 15 ; r = 12 ; s = 6 } |
