Changes in which measurements do not shift the equilibrium of a chemical system

1 answer:

4 0

Any Change in the amount of an inert gas into a gas-phase equilibrium at constant volume does not result in a shift of the equilibrium of a chemical system. This follows the equilibrium law.

<h3>What is Equilibrium law ?</h3>

According to this principle, Adding an inert gas into a gas-phase equilibrium at constant volume does not result in a shift.

This is because the addition of a non-reactive gas does not change the partial pressures of the other gases in the container.

While the total pressure of the system increases, the total pressure does not have any effect on the equilibrium constant.

use the heisenberg uncertainty principle to calculate the uncertainity in meters in the position of 0.68g and traveling at a vel

My name is Ann [436]

Answer:

7.7439×10⁻³¹ m

Explanation:

The expression for Heisenberg uncertainty principle is:

$\Delta x\times \Delta v=\frac {h}{4\times \pi\times m}$

Where m is the mass of the microscopic particle

h is the Planks constant

Δx is the uncertainty in the position

Δv is the uncertainty in the velocity

Given:

mass = 0.68 g = 0.68×10⁻³ kg

Δv = 0.1 m/s

Δx= ?

Applying the above formula as:

$\Delta x\times 0.1=\frac {6.62\times 10^{-34}}{4\times \frac {22}{7}\times 0.68\times 10^{-3}}$

<u>Δx = 7.7439×10⁻³¹ m</u>

In the molecule represented by the chemical formula H2SO4, there would be...Select one:a. 1 hydrogen atom.b. 2 hydrogen atoms.c.

REY [17]

<h2>Answer:</h2>

2 hydrogen atoms.

<h2>Explanations:</h2>

Given the chemical formula H2SO4,

The compound shows that the formula has 4 atoms of oxygen, one atom of sulfur and 2 hydrogen atoms.

Therefore, the number of hydrogen atom in the molecule H2SO4 is 2 hydrogen atoms.

Sergeeva-Olga [200]

Answer:

Explanation:

since, n = molar mass / empirical formula mass

Empirical formula mass = Total mass of atoms present in empirical formula

CHCl = 12+1+35.5

= 48.5

Given, Molar mass = 290.8 g.

So, n = 290.8/48.5

= 5.995 , that is approx 6.

So, Molecular formula = n × Empirical formula

= 6 × CHCl

= $C_{6}H_{6}Cl_{6}$

So, Number of C = 6
