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
Answer: 448 g of
will be required to completely react with 784g moles of CO(g) during this reaction.
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of
require = 1 mole of
Thus 28 moles of
will require=
of
Mass of
Thus 448g of
will be required to completely react with 784g moles of CO(g) during this reaction.
Equilibrium is a state of balance or a stable situation where the opposing forces cancel each other out and where no changes are occurring.
<h3>How to explain the equilibrium?</h3>
Your information is incomplete. Therefore, an overview will be given. In a chemical reaction, chemical equilibrium is a state where the reactants and products are present in concentrations that have no further tendency to change with time.
In terms of volume changes within a system at equilibrium, the following applies:
- When there is a decrease in volume, then the equilibrium will shift to favor the direction that produces fewer moles of gas.
- When there is an increase in volume, then the equilibrium will shift to favor the direction that produces more moles of gas.
In conclusion, if you increase the pressure of a system at equilibrium, the stress will be reduced by reaction that favors the side with the fewest moles of gas.
