Would you expect carboxylic acids with general formula CH3(CH2)nCOOH to become more or less water soluble as n increases? Explai

n.

Alexxx [7]4 years ago

Answer:

less soluble

Explanation:

As n increases, the non polar hydrocarbon tail increases in length, while there is only one polar carboxylic group at the end. Since only the carboxylic group can form hydrogen bond with water, and the non polar hydrocarbon tail cannot, the long tail will hinder the formation of hydrogen bond between acid and water molecules, hence solubility decreases.

A student lost part of his lab notebook and didn’t know what the original measure should have been. He knows that he calculated
igor_vitrenko [27]
Answer:

21.1cm or 10.1cm

Explanation:

Since the percent error is 35.5% and the experimental measurement was 15.6cm, the two possible values for the actual measurement are 15.6 plus 35.5% of 15.6 or 15.6 minus 35.5% of 15.6.

This is this:

15.6 + (0.355 x 15.6)
= 15.6 + 5.54
= 21.1cm

Or this:

15.6 - (0.355 x 15.6)
= 15.6 - 5.54
= 10.1cm

Write the equilibrium constant expression for this reaction: CH3OH (aq)+Cl-(aq)-&gt; CH3Cl(aq)+OH-(aq)
bulgar [2K]

Answer: K_c=\frac{[CH_3Cl]\times [OH^-]}{[CH_3OH]\times [Cl^-]}

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients. Pure solids are assumed to have a concentration of 1.

The given balanced equilibrium reaction is:

 CH_3OH(aq)+Cl^-(aq)\rightleftharpoons CH_3Cl(aq)+OH^-(aq)

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[CH_3Cl]\times [OH^-]}{[CH_3OH]\times [Cl^-]}

Thus the equilibrium constant expression for this reaction is K_c=\frac{[CH_3Cl]\times [OH^-]}{[CH_3OH]\times [Cl^-]}
