A mixture of CO (g) and excess O2(g) is placed in a 1.0 L reaction vessel at 100.0C and a total pressure of 1.50 atm. The CO is

umka2103 [35]

Answer:

Partial pressure of of CO₂ in the product mixture is 0,20atm

Explanation:

The balance equation is:

2CO(g) + O₂(g) → 2CO₂(g)

Total pressure of CO(g) and O₂(g) gases before reaction at 100,0°C and 1,0L is 1,50 atm. You can say:

X₁ + Y₁ = 1,50atm (1)

Where X₁ is initial partial pressure CO and Y₁ is initial partial pressure of O₂

After reaction partial pressures are:

X₂ = X₁ - 2n = 0; 2n = X₁

Y₂ = Y₁ - n

Z₂ = 2n

Where Z₂ is final partial pressure of CO₂

After reaction pressure at 100,0°C and 1,0L is 1,40 atm, that means:

1,40 atm = (Y₂ + Z₂)

1,40 atm = Y₁ - n + 2n

1,40atm = Y₁ + n

1,40 atm = Y₁ + X₁/2 (2)

Replacing (1) in (2)

1,40 atm = 1,50atm - X₁ + X₁/2

-0,10 atm = - X₁/2

0,20 atm = X₁.

As 2n = X₁; 2n = Z₂ = 0,20 atm

I hope it helps!

What is the wavelength of gamma ray electromagnetic radiation with a frequency of 2.73x10^20 Hz?

Amanda [17]

Answer:

1.10 × 10⁻¹² m

General Formulas and Concepts:

Chemistry - Atomic Structure

Speed of Light = Wavelength times Frequency

c = λν
c = 3.0 × 10⁸ m/s

Explanation:

Step 1: Define

ν = 2.73 × 10²⁰ Hz

Step 2: Find wavelength

3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)

λ = 1.0989 × 10⁻¹² m

Step 3: Check

We are given 3 sig figs. Follow sig fig rules.

1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m

Which of the following reagents should be used to convert to Question 26 options: A) H2, Lindlar's catalyst B) Na, liquid NH3 C)

diamong [38]

Answer: The question is is not complete...here is the complete question.

Which of the following reagents should be used to convert 3-Hexyne to E-3-hexene

Option B.

Na, liquid NH3.

Explanation:

3-Hexyne to E-3-hexene can be converted with by using the reagent of Na, NH3 (birch reduction) and this can be done by hdrogenation of H2.

The reagents NaNH3 convert 3-Hexyne to E-3-hexene because it is a reducing agents that convert or has the ability to reduce alkynes to trans alkenes.

3 Hexyne is an alkynes and it is converted to E- 3 hexene Na and NH3.

Calculate the volume in liters of a M potassium dichromate solution that contains of potassium dichromate . Round your answer to

maksim [4K]

The question is incomplete, here is the complete question:

Calculate the volume in liters of a 0.13 M potassium dichromate solution that contains 200. g of potassium dichromate . Round your answer to 2 significant digits.

Answer: The volume of solution is 5.2 L

Explanation:

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}$

We are given:

Molarity of solution = 0.13 M

Given mass of potassium dichromate = 200. g

Molar mass of potassium dichromate = 294.15 g/mol

Putting values in above equation, we get:

$0.13M=\frac{200}{294.15\times \text{Volume of solution}}\\\\\text{Volume of solution}=\frac{200}{294.15\times 0.13}=5.23L$

Hence, the volume of solution is 5.2 L
