Answer:

Esterification reaction

Explanation:

When we have to go from an acid to an ester we can use the <u>esterification reaction</u>. On this reaction, an alcohol reacts with a carboxylic acid on acid medium to produce an ester and water. (See figure).  

In this case, we need the <u>methyl ester</u>, therefore we have to choose the <u>appropriate alcohol</u>, so we have to use the <u>methanol</u> as reactive if we have to produce the methyl ester.

2. Food is another concern before the trip begins. Everyone has become accustomed to a 1500 calorie diet due the food
fomenos

About 46.1 pounds of apple would be needed per day of the trip.

I managed to extract the complete scenario from the attached image.

The trip is made up of 4 men and 3 women, making a total of 7 people.

Everyone has become accustomed to 1500 calories per day.

The total calories needed per day for 7 persons = 1500 x 7

                           = 10,500 calories

189 g of apple has only 95 calories, what g of apple will produce 10,500 calories?

                 = 10,500 x 189/95 = 20,889.67 g of apple

From conversion:

1 g = 0.00220462 pounds

20,889.67 g = 20,889.67 x 0.00220462

                         = 46.1 pounds of apple

Formic acid (HCO2H) has a dissociation constant of 1.8 x 10^-4 M. The acid dissociates 1:1. What is the [H+] if 0.35 mole of for
Tju [1.3M]
Initial [ HCO2H] = moles * volume 
                           =0.35 moles * 1 L = 0.35 M

by using ICE table:

              HCO2H ↔ H+  + HCO2-
initial      0.35 M        0          0
change  - X             +X          +X
Equ       (0.35 - X)       X          X

∴ Ka = [H+][HCO2-] / [HCO2H]

by substitution:

1.8 x 10^-4 =  X^2 / (0.35-X) by solving for X

∴ X = 0.0079 or 7.9 x 10^-3

∴ [H+] = X = 7.9 x 10^-3 M
