The 3 principles of the kinetic theory

Chemistry
1 answer:
jekas [21]4 years ago
5 0

Answer:

There are three main components to kinetic theory: No energy is gained or lost when molecules collide. The molecules in a gas take up a negligible (able to be ignored) amount of space in relation to the container they occupy.

Answer:

Ag₂CrO₄(s) + H⁺(aq) ⟶ 2Ag⁺(aq) + HCrO₄⁻(aq)

Explanation:

Ag₂CrO₄(s) ⇌ 2Ag⁺(aq) + CrO₄²⁻(aq).

Silver chromate is the salt of a strong base (AgOH) and a weak acid (H₂CrO₄).

HCrO₄⁻ is an even weaker acid than H₂CrO₄, so CrO₄²⁻ is a strong base.

Any added H⁺ will immediately combine with the chromate ions according to the reaction

H⁺ + CrO₄²⁻ ⟶ HCrO₄⁻

thereby removing chromate ions from solution.

According to Le Châtelier's Principle, more silver chromate will dissolve to replace the chromate ions that the H⁺  removes.

The overall equation for the reaction is

Ag₂CrO₄(s) ⇌ 2Ag⁺(aq) + <em>CrO₄²⁻(aq) </em>

<u>H⁺(aq) + </u><em><u>CrO₄²⁻(aq)</u></em><u> ⟶ HCrO₄⁻(aq) </u>

Ag₂CrO₄(s) + H⁺(aq) ⟶ 2Ag⁺(aq) + HCrO₄⁻(aq)

What are the roles of chlorophll, light, carbon dioxide, and water in the production of food and oxygen for a plant? (15 points
sweet [91]

Explanation:

Chlorophyll make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis. During the process of photosynthesis, plants release oxygen into the air. People and animals need oxygen to breathe.

The vapor pressure of ethanol is 400 mmhg at 63.5°c. its molar heat of vaporization is 39.3 kj/mol. what is vapor pressure of et
SVETLANKA909090 [29]

Answer:- The pressure of ethanol would be 109 mmHg.

Solution:- This problem is based on Clausius clapeyron equation--

ln(\frac{P_1}{P_2})=(\frac{\Delta Hvap}{R})(\frac{1}{T_2}-\frac{1}{T_1})

Given, T_1 = 63.5 + 273 = 336.5 K

T_2 = 34.9 + 273 = 307.9 K

P_1 = 400 mmHg

P_2 = ?

\Delta Hvap = 39.3 kJ/mol = 39300 J/mol

R = 8.314 J/mol.K

Let's plug in the values in the equation and do the calculations.

ln(\frac{400}{P_2})=(\frac{39300}{8.314})(\frac{1}{307.9}-\frac{1}{336.5})

ln(\frac{400}{P_2}) = 1.30

On taking anti ln to both sides...

\frac{400}{P_2} = e^1^.^3^0

\frac{400}{P_2} = 3.67

P_2 = 400/3.67

P_2 = 109 mmHg

For the reaction N2(g) + 3H2(g) ↔ 2NH3(g), the equilibrium constant, K, = 9.83 x 10-2 at a certain temperature and pressure.
pshichka [43]

The reaction is not at equilibrium and it is in the forward direction.

a.

Given,

[N₂] = 0.910 mol / L

[H₂] = 0.3 mol / L

[NH₃] = 0.0081 mol / L

K = 9.83 x 10⁻²

The balanced chemical equation for the given reaction is,

N₂(g) + 3H₂(g) ⇄ 2NH₃(g)

The formula of equilibrium constant is given by,

K = [NH₃]² / [N₂] [H₂]²

9.83 x 10⁻² = [(0.0081)² ]/ [0.910 × (0.3)²]

⇒9.83 x 10⁻² = (0.00006561) / (0.0819)

⇒9.83 x 10⁻² = 0.0008010989

⇒0.00983 = 0.0008010989

LHS ≠ RHS

Hence, the reaction is not at equilibrium.

b.

The reaction is in forward direction.
