True or false? To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from a 10.0 M stock solution, you should take 4.00 mL of the stock solution and add 20.0 mL of water.

Answers

Sorry I don’t know but o have to answer for pionts

False. To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from 10.0 M stock solution, 4.0 mL of the stock solution and 16.0 mL of water would be needed.  

Recall the law of diffusion that:

C1V1 = C2V2, where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

In this case, if C1 =10.0 M, V1 = ?, C2 = 2.00 M and V2 = 20.0 mL

V1 = 2 x 20/10

         = 4.0 mL

Hence, 4.0 mL of the stock solution would be taken. Since the final volume is 20.0 mL, only 16.0 mL of water would need to be added and not 20.0 mL.

A 20.0 mL of 0.27 M solution of the salt NaA has a pH of 8.70.

a) Calculate the pk, value of the acid HA.


(Correct to 3 sig. fig)

b) Calculate the pH of a solution containing 0.3 M HA and 0.1 M NaA.


(Correct to 3 sig. fig)

Answers

Answer:

a) 3.969

b) 3.489

Explanation:

a) Calculate the pk, value of the acid HA

PH of salt hydrolysis

P[tex]^{H}[/tex] = 1/2 ( pkw + pka + logC )

8.7 * 2 =  14 + log ( 0.27 )  + Pka

∴ Pka = 3.9686  ≈  3.969

b) Calculate the PH of a solution containing 0.3 M HA and 0.1 M NaA

PH = Pka + log ( salt / acid )

    = 3.9686 + log ( 0.1 / 0.3 )

    =  3.9686 - 0.48  = 3.489

Specific Heat Formula: q = mcΔT

q is heat (in Joules)m is mass (in grams)c is specific heat (in J/g °C)ΔT is change in temperatureExplanation:

Step 1: Define

[Given] m = 38.8 g

[Given] q = 181 J

[Given] ΔT = 36.0 °C - 25.0 °C = 11.0 °C

[Solve] c

Step 2: Solve for Specific Heat

Substitute in variables [Specific Heat Formula]:                                             181 J = (38.8 g)c(11.0 °C)Multiply:                                                                                                             181 J = (426.8 g °C)c[Division Property of Equality] Isolate c:                                                         0.424086 J/g °C = cRewrite:                                                                                                             c = 0.424086 J/g °C

A sample of hydrogen changes its pressure from 756 torr to 499 torr while the temperature remains constant. After the pressure is reduced, the volume of the gas is 789 mL. What was the original volume?​

Answers

P1 = 756 torr

P2 = 499 torr

V2 = 789 mL

V1 = ?

applying Boyle's Law

P1 * V1 = P2 * V2

756 torr * V1 = 499 torr * 789 mL

V1 = 499 torr * 789 mL / 756 torr

V1 = 520.78 mL

Which property of sulphuric acid makes it suitable to use as a catalyst for the preparation of esters?​

Answers

In Fisher esterification, sulfuric acid is used as a catalyst and its function is to convert the carboxylic compound in its conjugate acid. This favours the nucleophilic attack of the alcohol. To act as a catalyst you need a strong acid, therefore sulphuric acid is suitable for this kind of reaction.
