Im unsure :( maybe try looking up a calorie calculator
Answer:
k = 3.2 x 10¹¹
Explanation:
The equilbrium taking place is:
- N₂(g) + 3Cl₂(g) ↔ 2NCl₃(g)
And the expression for the equilbrium constant <em>k</em> is
- k = [NCl₃]² / ( [N₂] * [Cl₂]³)
We are given all the required data from the problem, so now we <u>solve for k</u>:
- k = (1.9x10⁻¹)² / ( (1.4x10⁻³) * (4.3x10⁻⁴)³ )
I think the answe would be 16n

Answer:</h3>
62.5 mL
<h3>
Explanation:</h3>
<u>We are given;</u>
- Molarity of the stock solution as 0.100 M
- Volume of the dilute solution as 250 mL
- Molarity of dilute solution as 0.0250 M
We are required to calculate the Volume of the stalk solution.
- Taking the volume and molarity of the stock solution to be V₁ and M₁ respectively, and volume and molarity of the dilute solution to be V₂ and M₂ respectively.
We are going to use the dilution formula;
- According to the dilution formula, M₁V₁ = M₂V₂
- Rearranging the formula;
V₁ = M₂V₂ ÷ M₁
= (0.025 M × 0.25 L) ÷ 0.100 M
= 0.0625 L
But, 1 L = 1000 mL
V₁ = 62.5 mL
Therefore, the volume of the stock solution is 62.5 mL
