Which particles are transferred during a redox reaction

Answers

Answer 1

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— .

Answer 2

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

Answers

Answer:

La reacción de etano, CH₃CH₃ y cloro, Cl₂ en presencia de luz solar se conoce como reacción de halogenación.

Los radicales de cloro se forman cuando el cloro se expone a la luz solar a continuación;

Cl₂ → 2Cl *

Se forma un radical etano cuando el etano, C₂H₆ reacciona con un radical libre de cloro, Cl *, como sigue;

C₂H₆ + Cl → C₂H₅ * + HCl

Se forma un producto halogenado cuando un radical libre de etano reacciona con una molécula de cloro como sigue;

C₂H₅ * + Cl₂ → C₂H₅Cl + Cl *

Un producto halogenado puede reaccionar además con un radical libre para producir como sigue;

In a chemical reaction, the number of moles of the reactants
A.

B.

C.
should never be equal to the number of moles of the products.
D.
may or may not be equal to the number of moles of the products.

Answers

Answer:

may or may not be equal to the number of moles of the products.

Explanation:

A chemical reaction involves the interaction between reactants to yield products. The number of moles of reactants and products in the system depends on the stoichiometry of the reaction.

The balanced reaction equation shows us the number of moles of reactants and products involved in the reaction.

Hence, in the balanced chemical reaction equation; the number of moles of reactants may or may not be equal to the number of moles of the products.

Which substance would you expect to dissolve most rapidly in 100 mL water?

A
0.4 g granulated sugar

B
0.2 g powdered sugar

C
0.4 g powdered sugar

D
0.2 g sugar cube

Answers

Answer:

b because it is just 0.2 g and powdered sugar has more contact surface than granulated sugar or sugar cube

The solubility can be given as the amount of solute that can be dissolved in the 100 ml of the solution. The most rapidly dissolved sugar in water is 0.2 gram powdered sugar.

What is a contact surface?

The contact surface can be given as the area of the compound that is in direct contact with the solution.

The solubility of the compound is found more in the solute with increased surface area.

The surface area of powdered sugar will be maximum, as more granules of the sugar will be in contact with the water than the cube or the granulated sugar.

Thus, the most rapid dissolution in water is found with 0.2 grams of powdered sugar. Thus, option B is correct.

17. A sample of oxygen gas has volume 150.0 mL, at 0.947 atm, what will be the volume of the gas at 750.12 mm of Hg if temperature remain constant.

Answers

Answer:

143.9 mL is the new volume for the gas.

Explanation:

Let's apply one of the gases law to solve this problem:

Boyle's law states that the product of pressure and volume remains constant when the T° is not modified.

P₁ . V₁ = P₂ . V₂

Be careful because we have T° in mmHg. We need to convert to atm:

750.12 mmHg . 1 atm / 760 mmHg = 0.987 atm

We replace data:

150 mL . 0.947 atm = 0.987 atm . V₂

V₂ = (150 mL . 0.947 atm) / 0.987 atm

V₂ = 143.9 mL

This term P . V comes from the Ideal Gases Law

P . V = n . R . T

A) 71 g of Cl2
B) 2.0 g of H2
C) 14 g of N2
D) 38 g of F2

Answers

Answer:

14 g of N2

Explanation:

If we look at the options, we will notice that the correct answer needs to be a gas that has about half of the molecular mass of the gas.

If we consider nitrogen gas whose molecular mass is 28g/mol, half of the molecular mass is 14 g.

So;

28g of N2 contains 6.02 × 10^23 molecules of N2

14g of N2 contains 14 × 6.02 × 10^23 /28

= 3.0 x 10^23

De la siguiente reacción química Fe2O3 + 3 H2O → __Fe(OH)3 para que se cumpla el balanceo en ella, en el espacio qué coeficiente estequiométrico se debe asignar

Answers

Answer:

Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

Explanation:

La ley de conservación de la materia establece que, dado que no se puede crear ni destruir ningún átomo en una reacción química, el número de átomos que están presentes en los reactivos debe ser igual al número de átomos presentes en los productos.

Luego, debes equilibrar la ecuación química. Para eso, primero debe mirar los subíndices al lado de cada átomo para encontrar el número de átomos en la ecuación. Si el mismo átomo aparece en más de una molécula, debes sumar sus cantidades.

Los coeficientes ubicados frente a cada molécula indican la cantidad de cada molécula para la reacción. Este coeficiente puede modificarse para equilibrar la ecuación, del mismo modo que nunca debe alterar los subíndices.

Al multiplicar el coeficiente mencionado por el subíndice, obtienes la cantidad de cada elemento presente en la reacción.

En este caso la reacción química es:

Fe₂O₃ + 3 H₂O ⇒ ____ Fe(OH)₃

Entonces, teniendo en cuenta todo lo anterior, se puede determinar la cantidad de elementos en cada lado de la ecuación:

Lado izquierdo: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos H Lado derecho: 1 hierro Fe, 3 oxígeno O y 3 hidrógenos H

Se puede observar que la reacción química no esta balanceada porque se tiene diferentes cantidades de cada elemento a cada lado de la reacción. Para equilibrarla, se comienza balanceando el hierro. Para eso, el coeficiente estequiométrico debe ser dos:

Fe₂O₃ + 3 H₂O ⇒ 2 Fe(OH)₃

Entonces:

Lado izquierdo: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos H Lado derecho: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos H

Ahora, a cada lado de la reacción se tiene la misma cantidad de cada elemento, por lo que la reacción esta balanceada.

Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

What is the molarity of a 750 milliliters solution containing 54.0 grams of KBr (help me please)

Answers

Answer: The molarity of KBr solution is 0.605 M

Explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.

The formula used to calculate molarity:

[tex]\text{Molarity of solution}=\frac{\text{Given mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (mL)}}[/tex]       .....(1)

Given values:

Given mass of KBr = 54.0 g

Molar mass of KBr = 119 g/mol

Volume of the solution = 750 mL

Putting values in equation 1, we get:

[tex]\text{Molarity of solution}=\frac{54.0\times 1000}{119\times 750}\\\\\text{Molarity of solution}=0.605M[/tex]

Hence, the molarity of KBr solution is 0.605 M

A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These four large planets, also called jovian planets after Jupiter, reside in the outer part of the solar system past the orbits of Mars and the asteroid belt. Jupiter and Saturn are substantially larger than Uranus and Neptune, and each pair of planets has a somewhat different composition.Although there are only four large planets in our solar system, astronomers have discovered thousands outside of it, particularly using NASA's Kepler Space Telescope. These exoplanets (as they are called) are being examined to learnmore about how our solar system came to be.
