What is the final acetate ion concentration when 69. g Ba(C2H3O2)2 is dissolved in enough water to make 970. mL of solution? The

mario62 [17]

Answer:

0.56M of acetate ions

Explanation:

Given parameters:

Mass of Ba(C₂H₃O₂)₂ = 69g

Volume of water = 970mL = 0.97dm³

Molar mass of Ba(C₂H₃O₂)₂ = 255.415g/mol

Unknown:

Concentration of acetate ion in the final solution = ?

Solution:

Let us represent the dissociation;

Ba(C₂H₃O₂)₂ = Ba²⁺ + 2C₂H₃OO⁻

We see that 1M of will produce 2M of acetate ions

Now, let us find the molarity of the barium acetate;

Molarity = $\frac{number of moles }{volume}$

Number of moles of Ba(C₂H₃O₂)₂ = $\frac{mass}{molar mass}$

Number of moles = $\frac{69}{255.415}$ = 0.27moles

Molarity of Ba(C₂H₃O₂)₂ = $\frac{0.27}{0.97}$ = 0.28M

since 1M of Ba(C₂H₃O₂)₂ will produce 2M of acetate ions

0.28M of Ba(C₂H₃O₂)₂ will produce 2 x 0.28 = 0.56M of acetate ions

The last answer choice us D. Adding more of the chemical will hear the water but only up to a certain temperature

enot [183]

D. Adding more of the chemical will heat the water but only up to a certain temperature

<h3>Further explanation</h3>

Chemical changes are changes in the process that produce new substances that are different from the initial/ forming substances. Chemical changes are usually known as chemical reactions. So there are products/reactions and reactants and there is a change in the molecule/particle

The chemical reaction is usually followed by the release of heat, gas, change in color, precipitate substance etc

The heat that occurs in the addition of chemicals is caused by the reaction with water. But there is a constant rise in temperature when water reaches <em>its maximum capacity to react with these chemicals.</em>

Evidenced by the addition of 15 g and 20 g of chemicals, the temperature changes are constant

nevsk [136]

Answer:

Phenols do not exhibit the same pka values as other alcohols;

They are generally more acidic.

Using the knowledge that hydrogen acidity is directly related to the stability of the anion formed, explain why phenol is more acidic than cyclohexane.

Explanation:

According to Bromsted=Lowry acid-base theory,

an acid is a substance that can release $H^{+}$ ions when dissolved in water.

So, acid is a proton donor.

If the conjugate base of an acid is more stable then, that acid is a strong acid.

In the case of phenol,

the phenoxide ion formed is stabilized by resonance.

$C_6H_5OH -> C_6H_5O^- +H^+$

The resonance in phenoxide ion is shown below:

Whereas in the case of cyclohexanol resonance is not possible.

So, cyclohexanol is a weak acid compared to phenol.
