Answer:
3.50*10^-11 mol3 dm-9
Explanation:
A silver rod and a SHE are dipped into a saturated aqueous solution of silver oxalate, Ag2C2O4, at 25°C. The measured potential difference between the rod and the SHE is 0.5812 V, the rod being positive. Calculate the solubility product constant for silver oxalate.
Ag2C2O4 --> 2Ag+ + C2O4 2-
So Ksp = [Ag+]^2 * [C2O42-]
In 1 L, 2.06*10^-4 mol of silver oxalate dissolve, giving, the same number of mol of oxalate ions, and twice the number of mol (4.12*10^-4) of silver ions.
So Ksp = (4.12*10^-4)^2 * (2.06*10^-4)
= 3.50*10^-11 mol3 dm-9
Density of the vinegar is higher than the density of the oil.
Explanation:
Density of the vinegar is higher than the density of the oil. The consequence of this is that the oil will be the top layer in the pitcher while the vinegar is at the bottom layer in the pitcher.
When mixing oil and vinegar will not produce a mixture because the oil contains non-polar molecules while vinegar is a solution of acetic acid in water and both of them are polar molecules.

The volume of carbon dioxide that will be produced is 191.4 g.
Calculation:
The following is the balanced equation for the given reaction:
Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g),
It is obvious that when 1.0 mole of Fe2O3 reacts with 3.0 mole of CO, 2.0 mole of Fe and 3.0 mole of CO2 are produced.
Hence by using cross multiplication:
If 2.0 mol of Fe was produced with → 3.0 mol of CO₂, from stoichiometry.
Then how many moles of CO₂ are produced by 2.9 mol of Fe?
To find the answer we have a formula:
∴ The no. of moles of CO₂ produced = (3.0 mol)(2.9 mol)/(2.0 mol) = 4.35 mol.
∴ The mass of CO₂ produced = no. of moles x molar mass = (4.35 mol)(44.0 g/mol) = 191.4 g.

Answer:
The reaction products is in the attached file
Explanation:
The nitro group is characterized by being a very strong inhibitor. Nitrobenzene nitration is checked at a reaction rate that is 10 times lower than that of benzene. The nitro group is characterized by being a goal counselor. The chemical reaction of nitrobenzene nitration with nitric and sulfuric acids, 93% of the substitution is verified in the target position.
