<span>During complete combustion, the hydrocarbon reacts with oxygen (O2) to from carbon dioxide (CO2) and water (H2O). For the combustion of one molecule of octane, 8 molecules of CO2 and 9 molecules of H2O must be formed to account for all the atoms of carbon and hydrogen in the octane. This requires 25 atoms of oxygen, or 12.5 molecules of O2:
C8H18+12.5*O2=9*H2O+8*CO2
Multiply both sides by 2 to obtain whole number coefficients:
2*C8H18+25*O2=18*H2O+16*CO2
The coefficient of carbon dioxide in the balanced equation is 16.</span>
Answer: They would both be pushed backward. (READ EXPLANATION)
Explanation:
Since your question has an error in it, I will provide two answers. If they were standing on their feet, they would not move. if they're both standing on skateboards, they would both move backwards because they have no friction on the ground. if both of them are standing on the same skateboard and pushing against each other, they would not move.
Answer: Molar mass of CO2 is 44 gram/mol. So,the mass of 1 mole or 6.02*10^23 molecules of CO2 is 44 grams
Explanation:
Answer:
I can provide a proper answer since there are no bonds specified.
Explanation:
The density of CO2 getting from experiment is 0.1/0.056 = 1.79 g/L. The percent error of this is (1.96 -1.79)/1.96*100%=8.67%. So the approximate percent error is 8.67%.
