Either covalent or ionic... they are nonmetals meaning that the are a component in both types of compounds
<u>Answer:</u> The value of equilibrium constant for the net reaction is 11.37
<u>Explanation:</u>
The given chemical equations follows:
<u>Equation 1:</u> ![A+2B\xrightarrow[]{K_1} 2C](https://tex.z-dn.net/?f=A%2B2B%5Cxrightarrow%5B%5D%7BK_1%7D%202C)
<u>Equation 2:</u> ![2C\xrightarrow[]{K_2} D](https://tex.z-dn.net/?f=2C%5Cxrightarrow%5B%5D%7BK_2%7D%20D)
The net equation follows:
![D\xrightarrow[]{K} A+2B](https://tex.z-dn.net/?f=D%5Cxrightarrow%5B%5D%7BK%7D%20A%2B2B)
As, the net reaction is the result of the addition of first equation and the reverse of second equation. So, the equilibrium constant for the net reaction will be the multiplication of first equilibrium constant and the inverse of second equilibrium constant.
The value of equilibrium constant for net reaction is:

We are given:


Putting values in above equation, we get:

Hence, the value of equilibrium constant for the net reaction is 11.37

Answer:
270. mL
General Formulas and Concepts:
<u>Acid-Base Titrations</u>
Dilution: M₁V₁ = M₂V₂
- M₁ is stock molarity
- V₁ is stock volume
- M₂ is new molarity
- V₂ is new volume
Explanation:
<u>Step 1: Define</u>
<em>Identify</em>
[Given] V₂ = 629.1 mL
[Given] M₂ = 11.2 M
[Given] M₁ = 26.1 M
[Solve] V₁
<u>Step 2: Find Stock Volume</u>
- Substitute in variables [Dilution]: (26.1 M)V₁ = (11.2 M)(629.1 mL)
- Multiply: (26.1 M)V₁ = 7045.92 M · mL
- Isolate V₁ [Cancel out units]: V₁ = 269.959 mL
<u>Step 3: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs as our lowest.</em>
269.959 mL ≈ 270. mL
