Question
10 grand of hexane (C6H12) combusts. how many grams of CO2 are formed? please assume unlimited oxygen is present to react with Hexane.
I need to be shown how to do the problem (step by step) and, do I do the same thing for all 3?
. 10 grams of Hexane (CoH2) combusts. How many grams of CO2 are formed? Please assume unlimited oxygen is present to react with Hexane (5 pts) 2. Octane (CaHs) combusts and 15 grams of water are formed. How many grams of octane were part of the combustion reaction; i.e. how many grams of octane reacted? Please assume unlimited oxygen is present to react with Octane (5 pts. 3.) 2-Butenal (CaHs) combusts, and 10 grams of carbon dioxide and 10 grams of water are formed. How many grams of C.Hs were present the start of the reaction? Please assume unlimited oxygen present to react with 2-Butenal (5 pts)Explanation / Answer
C6H12 + O2 ------------------ CO2 + H2O
C6H12 + 9 O2 ------------- 6 CO2 + 6 H2O
molar mass of Hexane (C6H12) = 86.18 gram/mole
mass of Hexane= 10 grams
molar mass of CO2= 44.01 gram/mole
number of moles of C6H12 = mass/molar mass = 10/86.18 =0.116 moles
number of moles of C6H12 = 0.116 moles
according to the balanced equation
1 mole of C6H12 = 6 moles of CO2 is produced
0.116 moles of C6H12 = ?
= 6x0.116/1 =0.696 mole
number of moles of CO2 is produced= 0.696 moles
mass of 1 mole of CO2 = 44.01 grams
mass of 0.696 moles of CO2 =?
= 44.01x0.696/1= 30.63 grams
mass of CO2 produced = 30.63 grams.
