In Experiment 1, salicylic acid was treated with an excess of acetic anhydride to synthesize aspirin. Once the reaction went to

completion, water was added to the flask and the solution was heated. What was the primary reason for adding water

Answer:

See explanation

Explanation:

Aspirin is a very important pain killer. The production of aspirin involves a reaction between salicylic acid and excess acetic anhydride.

Usually, a small amount of a mineral acid is added as a catalyst.

Aspirin is actually acetyl salicylic acid. When this substance is formed, the substance is not really soluble in water. Addition of water leads to the precipitation of the aspirin product.

Hence, the addition of water is mostly to precipitate the pure aspirin product after reaction.

One liter of a solution is found to contain 0.022 moles of HCl. Calculate the pH of the solution. Assume complete dissociation.
Ierofanga [76]

Answer:

The pH of the solution is 1.66

Explanation:

Step 1: Data given

Number of moles HCl = 0.022 moles

Molar mass of HCl = 36.46 g/mol

Step 2: Calculate molarity of HCl

Molarity HCl = moles HCl / volume

Molarity HCl = 0.022 moles / 1 L = 0.022 M

[HCl] = [H+] = 0.022 M

Step 3: Calculate pH

pH = -log [H+]

pH = -log(0.022)

pH = 1.66

The pH of the solution is 1.66

A compound was isolated and found to contain 72.2% magnesium and the rest nitrogen. What is the empirical formula of this compou
strojnjashka [21]
Since the compound is 72.2% Mg then there would be 27.8% N. Then you can just change it to 72.2 g Mg and 27.8 g N.
then convert to moles by dividing by molecular mass.
72.2÷24.31=2.96 moles Mg
27.8÷14.01=1.98 moles N
then divided by the lowest number.
2.96÷1.98=1.5
Since it is 1.5 you multiply by 2. so you have 3 Mg
1.98÷1.98=1 N
so the empirical formula is Mg3N

A compound with the empirical formula CH 2 CH2 has a molar mass of 126 126 g/mol. What is the molecular formula for this compoun
Pachacha [2.7K]

<u>Answer:</u> The molecular formula of the compound is C_9H_{18}

<u>Explanation:</u>

We are given:

Empirical formula of the compound = CH_2

For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is :

n=\frac{\text{Molecular mass}}{\text{Empirical mass}}

We are given:

Mass of molecular formula = 126 g/mol

Mass of empirical formula = 12+(2\times 1)]=14g/mol

Putting values in above equation, we get:

n=\frac{126g/mol}{14g/mol}=9

Multiplying this valency by the subscript of every element of empirical formula, we get:

C_{(9\times 1)}H_{(9\times 2)}=C_9H_{18}

Hence, the molecular formula of the compound is C_9H_{18}
