you decide to have a BBQ in your backyard. you have 1Kg of pentane (C5H12) in the tank. What is the amount of carbon dioxide (in mass and mols) you will be contributing to the greenhouse gas effect by using up that 1Kg of pentane?
plz.... need the answer with steps...thank you
balance the equation. Repost, and I will lead you to the solution.
C5H12 + 8O2 -----> 5CO2 + 6H2O
i balance the equation i hope its right.so what the next step....
To find the amount of carbon dioxide (CO2) produced from burning 1 kg of pentane (C5H12), we need to consider the balanced chemical equation for the combustion of pentane.
The balanced chemical equation for the combustion of pentane is:
C5H12 + 8O2 → 5CO2 + 6H2O
From the balanced equation, we can see that for every 1 mole of pentane (C5H12) burned, we get 5 moles of carbon dioxide (CO2) produced.
Now, let's calculate the molar mass of pentane (C5H12) and carbon dioxide (CO2):
Molar mass of pentane (C5H12) = (5 * molar mass of carbon) + (12 * molar mass of hydrogen)
= (5 * 12.01 g/mol) + (12 * 1.01 g/mol)
= 72.06 g/mol + 12.12 g/mol
= 84.18 g/mol
Molar mass of carbon dioxide (CO2) = (1 * molar mass of carbon) + (2 * molar mass of oxygen)
= (1 * 12.01 g/mol) + (2 * 16.00 g/mol)
= 12.01 g/mol + 32.00 g/mol
= 44.01 g/mol
Now, let's calculate the number of moles of pentane in 1 kg:
Number of moles of pentane = mass of pentane / molar mass of pentane
= 1000 g / 84.18 g/mol
= 11.88 mol
Since the molar ratio between pentane and carbon dioxide is 1:5, the number of moles of carbon dioxide produced will be:
Number of moles of carbon dioxide = number of moles of pentane * (5 moles of CO2 / 1 mole of C5H12)
= 11.88 mol * (5 mol CO2 / 1 mol C5H12)
= 59.4 mol CO2
Finally, to find the mass of carbon dioxide produced, we can use the molar mass of carbon dioxide:
Mass of carbon dioxide = number of moles of carbon dioxide * molar mass of carbon dioxide
= 59.4 mol * 44.01 g/mol
= 2611.794 g
Therefore, by using up 1 kg of pentane, you will be contributing approximately 2611.794 grams (or 2.611794 kg) of carbon dioxide to the greenhouse gas effect.
