7.20 moles of C3H8 are burned in a room with excess oxygen gas. How many moles of carbon dioxide are released into the atmosphere during this process ?
C3H8 + 5O2 --> 3CO2 + 4H2O
7.20 mols C3H8 x (5 mols O2/1 mol C3H8) = 7.20 x 5/1 = ?
36?
7.2 x 5 36
To find the number of moles of carbon dioxide released during the combustion of C3H8, we need to use the balanced chemical equation for the combustion reaction.
The balanced equation for the combustion of C3H8 is:
C3H8 + 5O2 -> 3CO2 + 4H2O
From the equation, we can see that for every molecule of C3H8 burned, 3 molecules of CO2 are produced.
Given that we have 7.20 moles of C3H8, we can use the mole ratio from the balanced equation to find the number of moles of CO2 produced.
Mole ratio: 1 mole of C3H8 produces 3 moles of CO2
So, to find the number of moles of CO2, we multiply the moles of C3H8 by the mole ratio:
7.20 moles of C3H8 * (3 moles of CO2/1 mole of C3H8) = 21.6 moles of CO2
Therefore, 7.20 moles of C3H8 will produce 21.6 moles of carbon dioxide.
