The difference between the amount of heat actually released upon the hydrogenation of benzene and that calculated for the hydrog

enation of an imaginary cyclohexatriene is called the _________ of benzene.
Chemistry

From what we know, we can confirm that the difference measured by the experiment in the heat released when compared to the hydrogenation of an imaginary cyclohexatriene is called the stabilization energy of benzene.

<h3>What is stabilization energy?</h3>

This is a term used to describe the difference in measured energy of a chemical structure compared to the theoretical energy amounts <u>expected </u>to be measured. In this experiment, the heat that was released <u>did not match</u> the <u>calculated </u><u>energy </u>expected, which is a prime example of stabilization energy at work.

Therefore, we can confirm that the difference measured by the experiment is called the stabilization energy of benzene.

(a) a 0.2 m potassium hydroxide solution is titrated with a 0.1 m nitric acid solution. (i) balanced equation: (ii)what would be
Stells [14]

\text{KOH} (aq) + \text{HNO}_3 (aq) \to \text{KNO}_3 (aq) + \text{H}_2\text{O} (l)

The solution shall contain only \text{KNO}_3 (aq) (and water) at the equivalence point. Both potassium hydroxide and nitric acid exist as strong electrolytes. As a result,  \text{KNO}_3 (aq), the salt derived from a reaction between the two species would undergo hydrolysis of a negligible extent. This neutralization reaction therefore be neutral at the equilibrium point.

The question states that the solution is "titrated with a ... nitric acid solution" indicating that \text{HNO}_3 is added to the initially-basic solution. PH value of the solution would keep decreasing as the volume of the acid added increases. The final solution would be acidic as it contains not only water and \text{KNO}_3 (aq), but some \text{HNO}_3 as well. Bromothymol blue would therefore demonstrates a yellow color, the color it present in an acidic solution, at the end of the titration.

If you were to react 4.3 miles of magnesium phosphide how many moles of potassium would you need?
bixtya [17]

Answer:

25.8

Explanation:

Let's write the reaction between magnesium-phosphide and potassium:

Mg3P2 + K = Mg + K3P

And now let's balance this equation:

Mg3P2+6K=3Mg+2K3P

We see that the ratio of magnesium-phosphide and potassium is 1:6, which means that for every mole of magnesium-phosphide there need to be 6 moles of potassium.

Since we have 4.3 moles of Mg3P2, there need to be 6 • 4.3 = 25.8 moles of potassium.

What is the molality of a solution that contains 418.8 g HCl in 4.62 kg water?
hram777 [196]

Answer:

a. 2.49

Explanation:

Molar mass of HCl= 36.46 g

So, no. of moles=418.8/36.46=11.48

Molality= no. of moles/mass of solvent= 11.48/4.62= 2.49
