<u>Answer:</u>
<u>For 1:</u> The amount of potassium iodate that were titrated is moles
<u>For 2:</u> The amount of sodium thiosulfate required is moles
<u>Explanation:</u>
- <u>For 1:</u>
To calculate the number of moles for given molarity, we use the equation:
Molarity of solution = 0.0100 M
Volume of solution = 25 mL
Putting values in above equation, we get:
Hence, the amount of potassium iodate that were titrated is moles
- <u>For 2:</u>
The chemical equation for the reaction of potassium iodate and sodium thiosulfate follows:
By Stoichiometry of the reaction:
2 moles of potassium iodate reacts with 1 mole of sodium thiosulfate
So, 0.00025 moles of potassium iodate will react with = of sodium thiosulfate
Hence, the amount of sodium thiosulfate required is moles
Answer:
The <u>equilibrium constant</u> is:
Explanation:
The correct equation is:
- N₂(g) + 3H₂(g) ⇄ 2NH₃(g)
Thus, with the equilibrium concentrations you can calculate the equilibrium constant, Kc.
The equation for the equilibrium constant is:
Substituting:
