Answer:

1. This reaction is (A) Exothermic .

2. When the temperature is decreased the equilibrium constant, K: (A) Increases

3.When the temperature is decreased the equilibrium concentration of Co2: (A) Increases

Explanation:

[tex]CoCl4^2-(aq) <--> Co_2+(aq) + 4Cl^-(aq)[/tex]

1. The pink color predominates at low temperatures, indicating that the commodity is preferred.

This is a reaction that is exothermic.

2. As the decrease in the temperature , the equilibrium constant , K ;

      equilibrium constant = [tex]\frac{product}{reactant}[/tex] =[tex]\frac{[CO^2^+][Cl^-^4]}{CoCl^2^-_4}[/tex]

As the temperature drops, the concentration of[tex]Cl^-[/tex] and [tex]CO^2^+[/tex] rises, and K rises as well , thus it increases .

3. The equilibrium concentration of [tex]CO^2^+[/tex] decreases as the temperature decreases:

When the temperature is lowered, the equilibrium shifts to the right , that is it increases.

Explanation:

Answer:

50%

Explanation:

This is a simple one trait Punnett square.

Because we know that the recessive trait is blue (yy) thanks to the text mentioning SpongeSusie being blue and recessive. Spongebob is yellow with a genotype of Yy or heterozygous. So we need two y to make a blue baby.

Yy X yy = 50% yellow Yy and 50% blue yy

Answer:

a) water expands when it freezes and damages the cell wall.

Explanation:

We know that most liquids expand when heated and contract when cooled. Water does not behave in the same way.

Water contracts on cooling from any temperature until 4°C when it begins to expand until 0°C. Hence a given mass of water has its least volume and highest density at 4°C.

Hence, fresh vegetables with high water content do not freeze well because water expands when it freezes and damages the cell wall.

Answer:

The concentration of hydrochloric acid would be estimated to be less.

Explanation:

This is because, the hydroxyl ions from water react with the hydrogen ions from the hydrochloric acid, hence decreasing the moles of hydrogen ions which lowers the acidic strength of Hydrochloric acid.

If water was used to rinse the burette and the burette is then used to dispense hydrochloric acid solution, the final estimate of hydrochloric acid concentration will be less.

It is usual to rinse the burette with the solution that ought to be in it after rinsing it with water.

However, in this case, the burette was was rinsed with water alone and then it was used to dispense the hydrochloric acid solution.

The water will dilute the hydrochloric acid solution thereby making the final estimate of hydrochloric acid concentration to be less.

Hence, if water was used to rinse the burette used to dispense the hydrochloric acid solution, the  final estimate of hydrochloric acid concentration will be less.

Answer:

a. 0.026 M

Explanation:

Molarity is a measure of the molar concentration of a solution. It can be calculated by using the following formula:

Molarity = n/V

Where;

n = number of moles (mol)

V = Volume of solution (L)

Based on the information provided;

V = 23.2mL = 23.2/1000 = 0.0232 L

n = ?

To get the number of moles of KHP, we use the formula:

mole = mass/molar mass

mole (n) = 0.123/204.2

mole (n) = 0.0006024mol

Molarity = n/V

Molarity = 0.0006024 ÷ 0.0232

Molarity = 6.024 × 10^-4 ÷ 2.32 × 10^-2

Molarity = 6.024/2.32 × 10^(-4--2)

Molarity = 2.59 × 10^-2

Molarity = 0.026 M

Answer:

Please find the report on the comet below

Explanation:

Specifically in the year 1993, a comet was discovered by three individuals namely: Eugene Shoemaker, Carolyn Shoemaker, and David Levy. The comet was named after the first discoverers as; Shoemaker-Levy 9.

Shoemaker-Levy 9 was reported to have already been in pieces as at the time of discovery. It was believed to have been torn apart by the gravitational force emanating from the biggest of the planets called JUPITER.

In July 1994, Shoemaker-Levy 9 came in contact with Jupiter in what seemed to be the end of the discovered comet. This collision of Shoemaker-Levy 9 with planet Jupiter was said to be the first ever solar systems collision observed.

Answer:

A

Explanation:

A scientist is a person who conducts scientific research to advance knowledge in an area of interest.

In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. It was not until the 19th century that the term scientist came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833.

Answer:

a. decrease the amount of the common ion in the system

Explanation:

The correct option is - a. decrease the amount of the common ion in the system

Reason -

Adding a common ion decreases solubility, as the reaction shifts toward the left to relieve the stress of the excess product.

Adding a common ion to a dissociation reaction causes the equilibrium to shift left, toward the reactants, causing precipitation.

Using ideal gas law–

We'll use formula,

PV = nRT

Where,

P, Pressure = 1.40 atm

V, Volume = 42.4 L

n, Number of moles = ( To find ) ?

T, temperature = 25°C

R, Ideal gas constant = 0.08206 L . atm/k. Mol

________________________________

Here, PV = nRT

Or, PV / RT = n

Or, [tex] \frac{1.40 \: atm \times42.4 \: litres }{298 \: k \: \times 0.08206 \: l.atm /k \: .mol} = n[/tex]

Or, n = 2.43 Moles.

Or, n = 2.43 Moles.
