Which shows the formula for an Organic acid
tresset_1 [31]
Answer:
            The formula of Organic acid is as follow,

                                                 R-COOH

Explanation:
                   The class of organic acids is called Carboxylic Acids. In above general structure, R is alkyl group and can vary. While -COOH is the functional group. 
                    Carboxylic Acids has the tendency to loose protons and their pKa value depends upon the alkyl group. For example the pKa value of Acetic acid (R = -CH₃) is 4.7. The driving force for this acidity is the stability of carboxylate (conjugate base) due resonance. i.e

                               RCOOH     ⇄    RCOO⁻  +  H⁺
Where;
            RCOO⁻  =  Carboxylate Ion (Conjugate base)

a balloon has a pressure of 104.5 kpa and a volume of 3.4L. If the pressure is reduced to 42.7 kpa, what will the volume change
Nuetrik [128]

Answer:

The answer to your question is 8,32 L

Explanation:

Data

Pressure 1 = 104.5 kPa

Volume 1 = 3.4 L

Pressure 2 = 42.7 kPa

Volume 2 = ?

Formula

- To solve this problem use the Boyle's law.

       P1V1 = P2V2

- Solve for V2

       V2 = P1V1 / P2

- Substitution

       V2 = (104.5)(3.4) / 42.7

-Simplification

       V2 = 355.3 / 42.7

- Result

        V2 = 8.32 L
