Acetic acid (CH3COOH) reacts with water to form the acetate ion and the hydronium ion: Upper C upper H subscript c upper C upper

O upper o upper H (a q) plus upper H subscript 2 upper o (l) double arrow upper C upper H subscript 3 upper C upper o upper O superscript minus (a q) plus upper H subscript 3 upper o superscript plus (a q). At equilibrium, the concentration of CH3COOH is 2. 0 × 10–1 M, the concentration of CH3COO– is 1. 9 × 10–3 M, and the concentration of H3O is 1. 9 × 10–3 M. What is the value of Keq for this reaction? 1. 8 × 10–5 5. 5 × 104 9. 5 × 10–3 1. 1 × 102.

The value of Keq for this reaction is \bold{1.8 \times 10^-^5}

The correct option is (A).

<h3>What is acetic acid?</h3>

Acetic acid is an organic compound also called ethanoic acid. It is a colorless liquid with a chemical formula   (CH_3COOH).

It has antibacterial and antifungal properties.

When acetic acid is reacted with water, it completely dissolves in it.

Thus, the correct option is A, \bold{1.8 \times 10^-^5}.

Answer:

See below  

Step-by-step explanation:

Matter is either a <em>pure substance</em> or a <em>mixture. </em>

Pure substances

  • Are composed of one type of atom or molecule.
  • Have a constant chemical composition
  • Have fixed chemical properties
  • Have fixed physical properties

              • For example, melting point, boiling point, density, solubility

Mixtures:

  • Consist of two or more substances not chemically combined
  • Have a variable composition
  • Can be separated into two or more components by physical means

             • For example, filtration, distillation, centrifugation

  • Each component retains its own properties

In the lab there is a vile of mercury and it has a mass of 43.0 grams. If the density of mercury is 13.6 g/mL, what is the volum
Vitek1552 [10]

Answer:

<h2>The answer is 3.16 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}

From the question

mass = 43 g

density = 13.6 g/mL

The volume is

volume =  \frac{43}{13.6}  \\   = 3.161764

We have the final answer as

<h3>3.16 mL</h3>

Hope this helps you

What is the VSEPR notation for the molecule
Ilya [14]
VSEPR notation gives a general formula for classifying chemical species based on the number of electron pairs around a central atom. However, not all species have the same molecules.

For example, carbon dioxide and surfer dioxide are both species, but one is linear and another one is bent.

Aspirin (C9H8O4) may be synthesized by mixing salicylic acid (C7H6O3) with excess acetic anhydride (C4H6O3).
diamong [38]

Answer:

65.18% is the percent yield for this reaction.

Explanation:

C_7H_6O_3 + C_4H_6O_3\rightarrow C_9H_8O_4 + C_2H_4O_2

Moles of salicyclic acid = \frac{2.0 g}{138 g/mol}=0.01449 mol

According to reaction 1 mole of salicyclic acid gives 1 mole of aspirin .

Then 0.01449 mole of salicylic acid will give :

\frac{1}{1}\times 0.01449 mol=0.01449 mol of asprin

Mass of 0.01449 moles of aspirin :

= 0.01449 mol × 180 g/mol = 2.6082 g

Theoretical yield of aspirin = 2.6082 g

Experimental yield of aspirin = 1.7 g

The percent yield for this reaction:

\%(Yield)=\frac{\text{Experimental yield}}{\text{Theoretical yield}}\times 100

=\frac{1.7 g}{2.6082 g}\times 100=65.18\%

65.18% is the percent yield for this reaction.
