Answer:

Vaporization

Since the question does not specify what molecule is being acted upon by the increment in temperature, I'll assume it's water.

When first taken out of the fridge, water is in the form of ice, and it has not been affected by a change in temperature yet, so it's at the origin.

(origin = ice)

As you raise the temperature, however, the ice starts to melt, and melting occur during phase 2. You have to keep the temperature constant for the process to properly occur.

(phase 2 = melting)

After it finishes melting, the ice is now in it's liquid state, which is water. The temperature continues to rise in order to proceed to the next phase.

(2nd slope = water)

Lastly, Water is being vaporized during phase 4. Notice, the temperature is kept constant in order to allow the process to properly occur.

(phase 4 = vaporization)

Dos moléculas de Clorato de Potasio en estado sólido, al aplicarle calor se descompone en dos moléculas de Cloruro de Potasio en estado sólido y tres moléculas diatómicas de Oxígeno en estado gaseoso ¿como se representan?

Answers

Answer:

2KClO3 (s) -------> 2KCl (s) + 3O2 (g)

Explanation:

Una ecuación de reacción química es una representación simbólica de lo que sucede en un recipiente de reacción.

Al escribir la ecuación de reacción química para una reacción particular, se utilizan los símbolos químicos de todas las especies involucradas.

Por la reacción. en el cual dos moléculas de Clorato de Potasio en estado sólido, al aplicar calor se descompone en dos moléculas de Cloruro de Potasio en estado sólido y tres moléculas diatómicas de Oxígeno en estado gaseoso, la ecuación de reacción se escribe así;

2KClO3 (s) -------> 2KCl (s) + 3O2 (g)

La regla para escribir ecuaciones de reacción química balanceada es que el número de átomos de cada elemento en el lado derecho de la ecuación de reacción debe ser el mismo que el número b de átomos del mismo elemento en el lado izquierdo de la ecuación de reacción.

Si realizamos un conteo de átomos simple en ambos lados de la ecuación de reacción, la regla se cumple

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. Which postulate of kinetic molecular theory best explains
how this is possible?
Attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly
O Collisions between gas particles are elastic, there is no net gain or loss of kinetic energy
Gases consist of a large number of small particles, with a lot of space between the particles
O Gas particles are in constant, random motion, and higher kinetic energy means faster movement

Answers

answer:Collisions between gas particlCollisions between gas particles or collisions with the vessel walls are perfectly elastic.

explanation:As long as an ideal gas is maintained at a constant temperature, the average kinetic energy of the molecules is said to be constant. In fact, what we call the temperature of a body at the macroscopic scale is just a representation of the kinetic energy carried by its atoms or molecules as they vibrate inside the body.

Now, if the kinetic energy of this oxygen gas is constant, it is because the collisions between the particles are assumed to be perfectly elastic. No energy is lost during the collisions. The rationale behind this assumption is that the particles are very tiny.

The answer which corresponds best to the explanation above is b. Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.

Which particles are transferred during a redox reaction

Answers

Answer:

Most oxidation-reduction (redox) processes involve the transfer of oxygen atoms, hydrogen atoms, or electrons, with all three processes sharing two important characteristics: (1) they are coupled—i.e., in any oxidation reaction a reciprocal reduction occurs, and (2) they involve a characteristic net chemical change— .

Electrons will be transferred during redox reaction.

What is electron?

The electron is subatomic particles which are placed in surrounding the nucleus. Electrons carry negative charge.

What is redox reaction?

Redox reaction involve the transfer of electrons between intermediates. A redox reaction occurs when the oxidation states of the substrate change. The removal of electrons or even a rise in the oxidation state of such a chemical or its atoms is referred to as oxidation. The acquisition of electrons or a lowering in the oxidation number of a chemical or the atoms inside it is referred to as reduction.

Hence the answer will be electron

reaction took place to produce a greyish black solid. After the reaction was completed
the solid was found to be magnetic.
5.1.1 Why was this greyish black solid magnetic?
5.1.2 Calculate the mass of Fos produced​

Answers

Answer:

The black solid is magnetic due to the special property of iron called ferromagnetism

6.9 g

Explanation:

The substance FeS is magnetic despite of the fact Fe^2+ is spin paired due to the special magnetic property of iron called ferromagnetism.

The equation of the reaction is;

Fe(s) + S(s) ----> FeS(s)

Number of moles of Fe = 5g/56g/mol = 0.089 moles

Since the reaction is 1:1, 0.089 moles of FeS is formed

For Sulphur;

Number of moles of sulphur = 2.5g/32 g/mol = 0.078 moles

Since the reaction is 1:1, 0.078 moles of FeS is formed

Hence sulphur is the limiting reactant.

So, mass of FeS produced = 0.078 × 87.91 g/mol = 6.9 g

If you start with 8.3 mL of 9.9M sulfuric acid, what is the theoretical yield of alum?

Answers

Answer:

19.5g is the theoretical yield of alum

Explanation:

Based on the balanced reaction, 4 moles of sulfuric acid produce 2 moles of alum. To solve this question we need to find the moles of H2SO4. With these moles we can find the moles of alum and its mass assuming all sulfuric acid reacts producing alum.

Moles Sulfuric Acid:

8.3mL = 0.0083L * (9.9mol/L) = 0.08217 moles sulfuric acid

Moles Alum:

0.08217 moles sulfuric acid * (2mol KAl(SO4)2•12H2O / 4mol H2SO4) =

0.041085 moles KAl(SO4)2•12H2O

Mass Alum -Molar mass: 474.3884 g/mol-

0.041085 moles KAl(SO4)2•12H2O * (474.3884 g/mol) =

Read the selection from the section "Molecules In Motion." The molecules in the hot soup are traveling faster overall than they did before the soup was heated. Conversely, the molecules in an ice cube are moving more slowly. Why did the author use the word "conversely"?

Answers

Answer: The author used the word "conversely" because the first statement he made is in CONTRAST to the second statement he made.

Explanation:

Matter is made up of atoms or molecules that are in constant motion. The motion of these tiny particles ( molecules) gives the object energy. The movement of these molecules depends on the state of matter which includes

--> GASEOUS STATE: Here, the particles are completely free to move and are always in motion.

--> LIQUID STATE: particles in this state slide by one another and are always in motion.

--> SOLID STATE: particles in this state are held tightly together but are always in motion.

Also, the molecules in motion are greatly affected by temperature changes. Increase in temperature will cause the particles in the liquid to move faster. Such is seen when soup is heated, the molecules travel faster than before. But the OPPOSITE is seen in an ice cube. This is because the ice cube is in solid state and of a lower temperature.

Which of the following substances are ionic?

Check all that apply.

Explanation:

An ionic substance is formed between a positively charged cation and a negatively charged anion.

Ionic substances are generally formed from metal and nonmetal atoms with the metal atoms forming the cations and the nonmetal atoms forming the anions.

Among the given substances,

MgI2 is an ionic substance.

Since Mg is the metal atom. It forms a cation.

I is a  nonmetal atom. It forms anion.

Hence,

MgI2 is an ionic substance.

Though AlCl3 looks like an ionic substance it is a covalent compound.

This is due to the high polarizability of [tex]Al^3+[/tex] ion.

The remaining two compounds do not contain any metal atoms.

So, ethanol and NH3 are not ionic compounds.
