The mass of pure acetic acid in 220 ml of the given solution at 20°C is 92.311 g

<h3>What is Acetic acid?</h3>

Acetic acid is a type of carboxylic acid and also known as ethanoic acid

Its formula is CH₃COOH.

It is an organic compound and is a colorless liquid

It is mostly used in the production of vinegar

40 % acetic acid by mass means,

40 g of acetic acid is dissolved in 100 g of solution.

The density of solution at 20°C,

\rho = 1.049 g/ml

We know,

\rho = \frac{m}{V}

V = \frac{m}{\rho}

The volume of the solution, V = \frac{100}{1.049} = 95.33 ml

95.33 ml of solution contains 40 g of pure Acetic acid

220 ml of solution contains\frac{40 \times 220}{95.33} = 92.311 g of pure Acetic acid

Thus, the mass of pure Acetic acid in 220 ml of solution at 20°C is 92.311 g

a) What substances are present in an aqueous buffer composed of HC2H3O2 and C2H3O2 - ?b) What happens when LiOH is added to a bu
Alex17521 [72]

Answer:

a) HC₂H₃O₂, C₂H₃O₂⁻, H₃O⁺, H₂O, OH⁻

b) HC₂H₃O₂ + LiOH ⇄ H₂O + LiC₂H₃O₂

c) C₂H₃O₂⁻ + HBr ⇄ HC₂H₃O₂ + Br⁻

Explanation:

a) In a HC₂H₃O₂/C₂H₃O₂⁻ buffer system, the following reactions take place:

HC₂H₃O₂ + H₂O ⇄ C₂H₃O₂⁻ + H₃O⁺

C₂H₃O₂⁻ + H₂O ⇄ HC₂H₃O₂ + OH⁻

Thus, the species present are: HC₂H₃O₂, C₂H₃O₂⁻, H₃O⁺, H₂O, OH⁻.

b) When LiOH is added to the buffer system, it is partially neutralized according to the following equation.

HC₂H₃O₂ + LiOH ⇄ H₂O + LiC₂H₃O₂

c) When HBr is added to the buffer system, it is partially neutralized according to the following equation.

C₂H₃O₂⁻ + HBr ⇄ HC₂H₃O₂ + Br⁻

When the final velocity is less than the initial velocity, this is speed time acceleration deceleration
WITCHER [35]

Hello!

When the final velocity is less than the initial velocity, this is deceleration

<h2>Why?</h2>

Acceleration is defined as the physical magnitude that measures the change in velocity with time. The units to express acceleration are speed over time.

The equation for acceleration is: a=\frac{v-v_o}{t-t_o}

Where: a=acceleration, v=final velocity, vo=initial velocity, t=final time, to=initial time.

If the final velocity is less than the initial velocity, then the acceleration is negative, and that is called deceleration. An example of this is when a car brakes.

Have a nice day!

Metallic bonding is possible because the electrons
Oksanka [162]
It is possible because the electrons in the energy level furthest from the nucleus delocalise, this leaves behind positively charged metal ions which are attracted to the negatively charged electrons that now move around the lattice freely
