You are asked to perform a reaction by dissolving hypochlorous acid in water. Based on your understanding of acids, you understa

nd that hypochlorous acid dissolves in water to form hydronium ions and hypochlorite ions. You then write out the equation:
HOCl + H2O ⇋ H3O⁺ + OCl⁻

Based on your understanding of Le Châtelier’s principle, complete the sentence. When additional hypochlorous acid is added, the hypochlorite ion “concentration”

According to the principle of chemical equilibrium, when additional hypochlorous acid is added, the hypochlorite ion concentration will increase.

<h3>What is chemical equilibrium?</h3>

Chemical equilibrium refers to the equilibrium which exists between chemical species in a reaction such that the rate of forward and backward reactions are the same.

Since the reaction is in equilibrium, when additional hypochlorous acid is added, the hypochlorite ion concentration will increase ad equilibriumwill shift to the right of the reaction.

Calculate the percent by mass of potassium nitrate in a solution made from 45.0 g kno3 and 295 ml of water. The density of water
Tanzania [10]

Answer:  the percent by mass of potassium nitrate is 13.3%

Explanation:

<u>1) Data:</u>

  • Mass of solute, m₁ = 45.0 g
  • Volume of solvent, V₂ = 295 ml
  • density of water, d₂ = 0.997 g/ml

<u>2) Formulae</u>:

  • Percent by mass, % = (mass of solute / mass of solution) × 100

  • Density, d = mass / volume

<u>3) Solution</u>:

  • d = mass / volume ⇒ m₂ = d₂ × V₂ = 0.997 g/ml × 295 ml = 294. g
  • mass of solution = m₁ + m₂ = 45.0g + 294. g = 339. g
  • % = (45.0 g / 339. g) × 100 = 13.3 %
  • The answer has to be reported with 3 significant figures.

Distinguish between the following:
defon

Hello, Tuilps2411!!

A) Heterogenous usually is referred as a mixture, whereas homogeneous is referred to as a solution. In a homogeneous solution, everything is uniform, which means everything works together and there is nothing that will happen since there is only one phase of matter in a homogeneous solution (air, vinegar). As for a heterogeneous mixture, things are not uniform and you can pick out things that are different/same (ice cubes out of a drink).

B) Whenever you mix things together, one will be a solute and a solvent. For a solute, it will be the one that is being dissolved (sugar). The other will be the solvent, which the one who does the dissolving (water).

C) In a pure substance, there is only one particle, whereas a mechanical mixture has two. You cannot see the particles in the pure substance, but you can in the mechanical mixture. You cannot separate a pure substance (gold), but you can in a mechanical mixture (pens in rice).

D) In an ionic bond, there is a bond there because the atoms are attracted due to their opposite charges (cation who has positive charge and anion which has a negative charge). Usually happen between a metallic and non-metallic atom. As for covalent bonds, they share one of multiple different atoms. They usually happen between two non-metallic atoms.

E) Density determines how much density there is in a certain thing. It will always be D = M/V. Density = Mass/Volume. As for mass, it determines how heavy (weight) things are.

F) Law of Conservation of Mass tells how the mass of the products in the reaction must equal the mass of the reactants. Law of Definite Proportions says that a compound always has its elements in a certain ratio by mass and does not depend on method of preparation. For Law of Multiple Proportions, it says that two elements bind with each other to create more than one compound, they are usually found in small whole number ratios whenever the one element is combined with a fixed weight.

I hope I helped!! If you need more help with anything else or do not understand, let me know and I will be more than happy to help you out more. Have a great evening!! :)

Consider the chemical equations shown here. C(s) + 2H2(g) → CH4(g) C(s) + 2Cl2(g) → CCl4(g) H2(g) + Cl2(g) → 2HCl(g) What is the
Vikentia [17]

Answer:

The answer to your question is below

Explanation:

(I)                               C(s) + 2H2(g) → CH4(g)

(II)                             C(s) + 2Cl2(g) → CCl4(g)

(III)                             H2(g) + Cl2(g) → 2HCl(g)

Process

Change (I)          CH4(g)        ⇒    C(s) + 2H2(g)

Add (I) and (II) C(s) + 2Cl2(g) ⇒ CCl4(g)

Result             CH4(g)  + C(s) + 2Cl2(g) ⇒  CCl4(g) + C(s) + 2H2(g)

Simplify           CH4(g)  2Cl2(g) ⇒  CCl4(g) + 2H2(g)     (IV)

Multiply (III) by 2     2( H2(g) + Cl2(g) → 2HCl(g))

                                  2 H2(g) + 2Cl2(g) → 4HCl(g)         (V)

Add (IV) and (V)

                           CH4(g) + 2Cl2(g) ⇒  CCl4(g) + 2H2(g)

                          2 H2(g) + 2Cl2(g) ⇒  4HCl(g)  

   CH4(g) + 2Cl2(g) +  2 H2(g) + 2Cl2(g) ⇒  CCl4(g) + 2H2(g) +  4HCl(g)  

Simplify

           CH4(g) + 4Cl2(g)  ⇒  CCl4(g) + 4HCl(g)

What was the initial volume of gas if a new volume of 3.00 liters is obtained when the pressure is decreased from 3.00 atm to 1.
timurjin [86]

Answer:

1 L

Explanation:

V1=P2V2/P1

Checking this, it is correct because P and V at constant T has an inverse relationship.

I just need help on 4 and 5 please ​
vampirchik [111]

Answer:

4. 12 km.

5. 2 km.

Explanation:

Hello!

In this case, we need to distinguish between two terms:

- Distance traveled: it stands for the total displacement, no matter the initial and final position the body has; it means that the total displacement was:

DT = 3km + 4 km + 3 km + 2 km = 12 km.

- Displacement: it stands for the relationship between the initial position and the final one, it means that the initial position was 0 km and the final one is 2 km away, thus, the displacement is:

D = 2km - 0 km = 2 km.

Best regards!
