Determine the balanced chemical equation for this reaction.
\(2C_8H_{18(g)}+25O_{2(g)}→16CO_{2(g)}+18H_2O_{(g)}\)
0.360 mol of octane is allowed to react with 0.860 mol of oxygen. Which is the limiting reactant? My ans is oxygen because I only got 25.6 g while octane has 41.04 g.
How many moles of water are produced in this reaction?
I need help with this one... here is my solution:
0.63 mol O2 x (18 mol H2O /25 mol O2) = 0.576 mol of H2O
but it is wrong.

Best ResponseYou've already chosen the best response.0oops! I missed the coefficients. but I have the same balanced equation on my paper. Do you know how to work this one out?

Best ResponseYou've already chosen the best response.2the oxygen is the limiting reactant 0.360 mol C8H18 x 16/2=2.88 moles ofCO2 0.860 moles O2 x 16/25 = 0.55 moles CO2

Best ResponseYou've already chosen the best response.0nvm, i know which part i did wrong.. i used 0.63 moles of oxygen instead of 0.86 thanks anyway :)

Best ResponseYou've already chosen the best response.2there is 0.860 moles of O2!!! I dont know why you put 0.63 0.860 mol O2 x (18 mol H2O /25 mol O2) = 0.6192 mol of H2O

Best ResponseYou've already chosen the best response.0i honestly don't know where i get that 0.63, i must be too tired now xD
