Properties: Chlorine has a melting point of -100.98°C, boiling point of -34.6°C, density of 3.214 g/l, specific gravity of 1.56 (-33.6°C), with a valence of 1, 3, 5, or 7. Chlorine is a member of the halogen group of elements and directly combines with almost all of the other elements.

How many liters of water are needed to make a 4.00 M solution using 75.0

timurjin [86]

Answer:

0.22L

Explanation:

Given parameters:

Concentration of solution = 4.00M

Mass of lithium Bromide = 75g

Unknown:

Volume of water = ?

Solution:

Concentration in terms of the molarity is the number of moles of solute in a solution.

Molarity = $\frac{number of moles }{volume of solution}$

let us find the number of moles first;

Number of moles = $\frac{mass}{molar mass}$

Molar mass of LiBr = 7 + 80 = 78g/mol

number of moles = $\frac{75}{78}$

number of moles = 0.96moles

Volume of water = $\frac{number of moles }{molarity}$ = 0.96/4 = 0.22L

Place the following in order of increasing acid strength.

Romashka-Z-Leto [24]

I think the correct order according to increasing acid strength would be the one in option B. The order is:
HBrO < HBrO2 < HBrO3 < HBrO4

The more oxygen atoms means the easier the hydronium ions is removed in aqueous solution since the oxygen has a high electronegativity.

When separating benzoic acid, naphthalene, and 3-nitroaniline, identify the solution used for each described purpose.

mamaluj [8]

Answer:

a. Extract reconstituted 3-nitroaniline out of the aqueous layer: Dichloromethane.

b. Extract benzoic acid into the aqueous layer: 5% NaOH.

c. Extract aniline into the aqueous layer: 5% HCl.

d. Reconstitute aniline from aqueous layer: 6M NaOH.

Explanation:

Each of the answers is explained as follows:

a. Extract reconstituted 3-nitroaniline out of the aqueous layer: Dichloromethane.

Dichloromethane is an organochloride chemical and CH2Cl2 is its formula. It is commonly employed as a solvent since it is a colorless, volatile liquid with a sweet, chloroform-like odor. It is polar and miscible with numerous organic solvents, despite not being miscible with water.

b. Extract benzoic acid into the aqueous layer: 5% NaOH.

According to the Mass by Volume percentage concept, 5% NaOH solution (W/V) indicates 5g of NaOH dissolved in 100ml of water.

c. Extract aniline into the aqueous layer: 5% HCl.

Hydrochloric acid (HCl) is a common acid found in the human body as well as in laboratories, and it is a key component of stomach acid.

As a result, 5% HCl solution is made by mixing 8.26 mL concentrated HCl with roughly 50 mL distilled water, stirring well, and then adding water up to 100 mL.

d. Reconstitute aniline from aqueous layer: 6M NaOH.

6M NaOH refer to 6 moles in 1L MW (NaOH). Therefore, 6 moles of NaOH are dissolved in 1 liter of H2O to make a 6M NaOH solution. Because NaOH has a molar mass of 39.9997 g/mol, we'll need 240 g NaOH (39.997 x 6) in 1L of H2O to make a 6M solution.
