23. Which of the following solutions will reach dynamic equilibrium?
a Supersaturated solution
b Unsaturated solution
C Saturated solution
d None of the above

Answers

Answer:

C

Explanation:

The solution that will reach dynamic equilibrium is a saturated solution. The correct option is C.

What is an unsaturated solution?

A chemical solution in which the solute concentration is less than its equilibrium solubility is known as an unsaturated solution.

The solvent dissolves the entire solute.

When a solute (typically a solid) is mixed with a solvent (commonly a liquid), two reactions take place at the same time.

Thus, the correct option is C, the saturated solution.

What is equilibrium?

Chemical equilibrium is a state where no net change in the amounts of reactants and the products occurs during a reversible chemical reaction.

A reversible chemical reaction happens when the products react with the original reactants as soon as they are generated.

On a treadmill, you are walking continuously but not going anywhere, which can be said as equilibrium.

Thus, the correct option is B.

Many people try to eliminate fat from their diets. Which is one reason it is
necessary for humans to eat fat?

Answers

Answer:

C

Explanation:

While it is common to notice that many people avoid food that contain fat due to the fact that they are avoiding the adverse implications of fat consumption, the consumption of fat also has some advantages.

Prominent among the advantages of fat in the body is that fat cushions the internal organs. This cushioning of the internal organs avoids sudden damage to these organs.

For this reason, it is necessary for humans to eat fat.

As the compound has alkyne as the functional group the correct option is A.

Functional group is defined as a substituent or a group of atoms or an atom due to which chemical reactions are carried out. Each functional group will react in the same way regardless to the parent carbon chain to which it is attached.This helps in prediction of chemical reactions.

The reactivity of functional group is increased by making modifications in the functional group .Atoms that  are present in functional groups are linked to each other by means of covalent bonds.They are named along with the organic compounds according to IUPAC nomenclature.

Answers

Answer:

Chemical reactions and physical transformations do not create or destroy mass in an isolated system, according to the law of conservation of mass. The mass of the products in a chemical reaction must equal the mass of the reactants, according to the conservation of mass law. The law of conservation of mass can be used to solve for unknown masses, such as how much gas is consumed or produced during a reaction.

Calculate the volume that 12.5 g of carbon dioxide gas will occupy at a temperature of 45 degrees Celsius and a pressure of 1.20 atm

Answers

Answer:

[tex]V=6.2L[/tex]

Explanation:

Hello there!

In this case, according to the given information, it is possible for us to realize that we need to use the ideal gas equation in order to calculate the volume of CO2 but firstly calculating the moles:

[tex]n=\frac{12.5g}{44.01g/mol}=0.284mol[/tex]

Then, we proceed with the ideal gas equation to solve for volume:

[tex]PV=nRT=\\\\V=\frac{nRT}{P}\\\\V=\frac{0.284mol*0.08206\frac{atm*L}{mol*K}*(45+273.15)K}{1.20atm}\\\\V=6.2L[/tex]

Balancee las ecuaciones químicas por el método de tanteo e identifique que tipo de reacción es: 1.1.- Cloruro férrico acuoso reacciona con carbonato de sodio sólido para formar carbonato férrico sólido y cloruro de sodio acuoso.

Answers

Respuesta:

2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + 6 NaCl(aq)

Explicación:

Consideremos la ecuación no balanceada que ocurre cuando cloruro férrico acuoso reacciona con carbonato de sodio sólido para formar carbonato férrico sólido y cloruro de sodio acuoso. Esta es una reacción de doble desplazamiento.

FeCl₃(aq) + Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)

Vamos a usar el método de tanteo. Empezaremos balanceando los átomos de C, multiplicando Na₂CO₃ por 3.

FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)

Luego, balancearemos los átomos de Fe, multiplicando FeCl₃ por 2.

2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)

Finalmente, obtendremos la ecuación balanceada, multiplicando NaCl por 6.

2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + 6 NaCl(aq)

If the kinetic and potential energy in a system are equal, then the potential energy increases. What happens as a result?

Answers

Answer: As a result an increase in kinetic energy also happens.

Explanation:

Potential energy is the energy occupied by an object or substance due to its position.

Kinetic energy is the energy occupied by an object of substance due to its motion.

If the kinetic and potential energy in a system are equal and then an increase in potential energy will occur.

As a  result, there will also occur an increase in kinetic energy also.

Thus, we can conclude that as a result an increase in kinetic energy also happens.

To test this theory, she took a sample of 150 art students and found that p^=14% of the sample was left-handed.To see how likely a sample like this was to happen by random chance alone, Lilianna performed a simulation. She took a sample of n=150 students from a population where 10% of the students were left-handed, and she recorded what proportion of the sample was left-handed. She repeated this process for a total of 50 samples. Here are the sample proportions from her 50 samples:She wants to test H0:p=10% vs. Ha:p>10% where p is the proportion of art students at her university who are left-handed.Based on these simulated results, what is the approximate p-value of the test?Note: The sample result was p^=14%.
