3 0

The methyl salicylate (wintergreen oil) is the methyl ester of salicylic acid.

Methyl salicylate is produced by esterifying salicylic acid with methanol, the reaction scheme is attached to this answer. In the past, it was commonly distilled from the twigs of Betula lenta (sweet birch) and Gaultheria procumbens (eastern teaberry or wintergreen).

How many grams are needed to prepare 750. mL of a 0.35 M solution of NaOH?
nikdorinn [45]

Answer:

10.5grams

Explanation:

Molarity = number of moles (n)/ volume (V)

According to this question;

Volume = 750 mL = 750/1000 = 0.75L

Molarity = 0.35M

number of moles (n) = molarity × volume

n = 0.35 × 0.75

n = 0.2625mol

Using mole = mass/molar mass

Molar Mass of NaOH = 23 + 16 + 1

= 40g/mol

mole = mass/molar mass

0.2625 = mass/40

mass = 10.5grams

10.5 grams are needed to prepare 0.75L of a 0.35 M solution of NaOH.

Decide which element probably forms a compound with oxygen that has a chemical formula most and least similar to the chemical fo
mafiozo [28]

Answer:

Most similar   -----  Lithium

Least similar   ----  Nitrogen

Explanation:

Cesium is an element on the periodic with the atomic number 133. It lies in group 1 (i.e., the alkali metals) and period 6 on the periodic table. The oxidation state of group 1 metals is +1. Cesium forms an oxide with oxygen as  Cs_2O.

The most similar compound to this chemical compound is Lithium because Lithium happens to be in the same group one metal with Cesium and forms the compound Li_2O with the oxygen

The least similar compound nitrogen due to fact that it is an oxide that is covalent in nature and lies between-group 3 -17  to form an NO_2 with oxygen.

Rank the following solutions in order of increasing acidity (least acidic to most acidic): I: [H3O+] = 1x10−5 II: [OH−] = 1x10−1
kozerog [31]

Answer: option C) II < III < I

i.e [OH−] < [H3O+] < I

Explanation:

First, obtain the pH value of I and II, then compare both with III.

For I

Recall that pH = -log (H+)

So pH3O = -log (H3O+)

= - log (1x10−5)

= 4

For II

pOH = - log(OH-)

= - log(1x10−10)

= 9

For III

pH = 6

Since, pH range from 1 to 14, with values below 7 to be acidic, 7 to be neutral, above 7 to be alkaline: then, 9 < 6 < 4

Thus, the following solutions from least acidic to most acidic is II < III < I
