Explanation:
We have the following reaction
Now we calculate the limit reagents, to know which of the two gases is completely depleted and which one is in excess.
Excess gas will remain in the tank when the reagent limits have run out and the reaction ends.
To calculate the limit reagent, we must calculate the mols of each substance. We use the ideal gas equation
We cleared the mols
PV=nrT
replace the data for each gas
Constant of ideal gases
Transform degrees celsius to kelvin
Find the limit reagent by stoichiometry
Using as the limit reagent produces more than I have, so oxygen is my excess reagent and will remain when the reaction is over.
Using as the limit reagent produces less than I have, so is my excess reagent and will remain when the reaction is over.
Calculate the moles that are formed of
We know that for all to react, 0.04 mol is consumed.
we subtract the initial amount of less than necessary to complete the reaction. And that gives us the amount of mols that do not react.
The remain gases are and
calculate the volume that gases occupy
Calculate partial pressures with the ideal gas equation
