Question

How many (propane) must be reacted according to the following balanced chemical reaction to transfer of heat? c₃h₈(g) o₂(g) → co₂(g) h₂o(g)

Answer 1

In the balanced chemical reaction for the combustion of propane, we see that for every 1 mole of propane reacted, 5 moles of oxygen are required.

Step-by-step explanation:

In the balanced chemical reaction for the combustion of propane, C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g), we can see that for every 1 mole of propane reacted, 5 moles of oxygen are required to completely combust it.

Therefore, if we know the amount of propane, we can determine the amount of oxygen required using the same ratio.

In this case, since the volume of propane is given as 2.7 L and the volume of oxygen is unknown, we would need to convert the volume of propane to moles and then use the stoichiometric ratio to calculate the volume of oxygen needed.
