Can someone show me the answer to this as I am well confused.
What mass of lead oxide reacts with 2400dm3 of carbon monoxide?
What temperature? what pressure? Is that at STP? What Pb; i.e., PbO or PbO2. IF at STP, then mols CO = 2400 cm3/22.4 dm3 = ?
But I can't even write an equation with know the kind of lead oxide.
Hi sorry, Pbo at room temperature
Pbo + co = Pb + co2
C'mon. Use that caps key when needed.
PbO + CO ==> Pb + CO2
Use PV = nRT and solve for n = number of mols for CO at room T. T will be 298 K if you use 25C as room T. V will be 2400 and P will be 1 atm.
Then convert mols CO to mols PbO using the coefficients in the balanced equation,
Finally, gams PbO = mols PbO x molar mass PbO.
To determine the mass of lead oxide that reacts with 2400 dm3 of carbon monoxide, we need to use stoichiometry, which involves balancing the chemical equation and using the molar ratios between the reactants and products.
Assuming the balanced reaction is:
PbO + CO -> Pb + CO2
Step 1: Determine the molar ratio
From the balanced equation, we can see that 1 mole of PbO reacts with 1 mole of CO.
Step 2: Convert volume to moles
To calculate the number of moles of CO, we need to use the ideal gas law:
PV = nRT
Given the volume of CO (2400 dm3), we also need to know the temperature and pressure at which this reaction takes place.
Step 3: Calculate the molar mass of CO
The molar mass of CO is 28 g/mol (carbon's molar mass = 12 g/mol, oxygen's molar mass = 16 g/mol).
Step 4: Calculate the moles of CO
Divide the given volume of CO (2400 dm3) by the volume of 1 mole of any gas at standard temperature and pressure (22.7 dm3 at STP). This will give you the number of moles of CO.
Step 5: Calculate the mass of PbO
Since the molar ratio between PbO and CO is 1:1:
Mass of PbO = Moles of CO x Molar mass of PbO
Now, with the appropriate values determined, you can calculate the mass of PbO that reacts with 2400 dm3 of CO.
