Answer:
Explanation:
They gave us the masses of two reactants and asked us to determine the mass of the product.
This looks like a limiting reactant problem.
1. Assemble the information
We will need a chemical equation with masses and molar masses, so, let's gather all the information in one place.
Mᵣ: 239.27 32.00 207.2
2PbS + 3O₂ ⟶ 2Pb + 2SO₃
m/g: 2.54 1.88
2. Calculate the moles of each reactant
3. Calculate the moles of Pb from each reactant
4. Calculate the mass of Pb
Answer:
zero
Explanation:
I I think one should be so accurate with measurements and experiments
For each shift, you will earn 12/60*75=15 dollars=60 quarters. If the laundry is 12 quarters per load, you can make 60/12=5 loads. If the laundry is 16 quarters, you can make 60/16=3.75 loads. You can pay only 3 loads.
The given reaction is
2 SO2 + O2 <=> 2 SO3, for which kp = 2 at a given temperature
Equilibrium constant = pSO3^2 / pSO2^2 X pO2
Q= (3.4)^2 / (2.2)^2 X 1.6 = 1.5
As Q< Kp
The reaction is not at equilibrium and reaction will go in forward direction
