Final Answer

Thank you for the opportunity to help you with your question!
2C6H6 + 15O2 ---> 12CO2 + 6H2O
from the balanced equation, the ratio between any 2 substances can be determined by taking the coefficients in front of each.
for example, the ratio between Oxygen and propane is 15 : 2, which means there are 15 moles of O2 required to completely react with 2 mole of C6H6.
Please let me know if you need any clarification. I'm always happy to answer your questions.if 2 moles of C6H6 can be combusted using 15 moles of O2,then 1 mole of C6H6 will combusted using 7.5 moles of O2

1. 1.1%
2. 10.2%
3. 16.4%

5. 19.6%
My guesswork
moles H2SO4 = 1.74
mass H2SO4 = 2.00 mol x 98.078 g/mol=170.69 g
mass water = 1 Kg = 1000 g
1000+170
mass solution = 1170.7 g
% = 170.7 x 100/ 1170.7=14.58

My work, I really don’t know if I did this right….
T1 = 25 + 273 = 298 K
T2 = 75 + 273 = 348 K
ln(k1/k2) = (Ea/R) (1/T2 - 1/T1))
ln (k/2.64 x 10^-2 ) = (74000 / 8.3145) ( (1 / 298 )- (1 / 348) )
ln( k/2.64 x 10^-2 )= 4.29
e ^ 4.29 = 72.9664

mole fraction water = 5 / 5 + 0.161 =0.969
