The reducing agent is oxidized during a redox reaction

$\boxed{\boxed{\bold{Further~explanation}}}$

The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number

3 basic theories explain this Redox concept:

1. Binding/release of oxygen

The oxidation reaction is the binding of a substance with oxygen. (O₂)

For example:

2SO₂ + O₂ ----> 2SO₃

The reduction reaction is the release of oxygen from a substance.

For example:

2CuO → 2Cu + O₂

2. Electron release / binding reaction

Oxidation is an electron release event

Example:

2F ---> 2Fe³⁺ + 6e⁻

The reduction is an electron capture event

Example:

3O₂ + 6e⁻ ---> 3O²⁻

3. The reaction of addition/reduction of oxidation number

Oxidation is an increase/increase in oxidation number, while reduction is a decrease/decrease in oxidation number.

In this reaction, it is also known

Reducing agents are substances that experience oxidation

The oxidizer is a substance that is reduced

Let's look at the answer choices

The reducing agent is reduced.

This statement is wrong because the reducing agent undergoes oxidation

The reducing agent is oxidized.

This statement is true

The reducing agent remains unchanged.

The statement is wrong because the oxidation number of the oxidized compound will increase

The reducing agent gains electrons.

The statement is wrong because the reducing agent releases electrons

So the correct statement is B The reducing agent is oxidized

Identify the solute with the highest van't Hoff factor. And how do you determine which one is highest?

german

Answer : The correct option is, (A) $AlCl_3$

Explanation :

Van't Hoff factor : It is defined as the ratio of the experimental value of the colligative property to the calculated value of the colligative property.

We can determine the van't Hoff factor by the association and dissociation of the compound.

(A) $AlCl_3$

It is an electrolyte that dissociates to give aluminum ion and chloride ion.

The dissociation of $AlCl_3$ will be,

$AlCl_3\rightarrow Al^{3+}+3Cl^{-}$

So, Van't Hoff factor = Number of solute particles = $Al^{3+}+3Cl^{-}$ = 1 + 3 = 4

(B) $KI$

It is an electrolyte that dissociates to give potassium ion and iodide ion.

The dissociation of $KI$ will be,

$KI\rightarrow K^{+}+I^{-}$

So, Van't Hoff factor = Number of solute particles = $K^{+}+I^{-}$ = 1 + 1 = 2

(C) $CaCl_2$

It is an electrolyte that dissociates to give calcium ion and chloride ion.

The dissociation of $CaCl_2$ will be,

$CaCl_2\rightarrow Ca^{2+}+2Cl^{-}$

So, Van't Hoff factor = Number of solute particles = $Ca^{2+}+2Cl^{-}$ = 1 + 2 = 3

(D) $MgSO_4$

It is an electrolyte that dissociates to give magnesium ion and sulfate ion.

The dissociation of $MgSO_4$ will be,

$MgSO_4\rightarrow Mg^{2+}+SO_4^{2-}$

So, Van't Hoff factor = Number of solute particles = $Mg^{2+}+SO_4^{2-}$ = 1 + 1 = 2

(E) Non-electrolyte

The dissociation non-electrolyte is not possible. So, the Van't Hoff factor will always be, 1.

Hence, the highest van't Hoff factor of solute is, $AlCl_3$

The atomic symbol Superscript 206 subscript 82 upper P b. represents lead-206 (Pb-206), an isotope that has 82 protons and 124 n

Serggg [28]

Answer:

\left \{ {{y=206} \atop {x=82}}Pb \right.

Explanation:

isotopes are various forms of same elements with different atomic number but different mass number.

Radioactivity is the emission of rays or particles from an atom to produce a new nuclei. There are various forms of radioactive emissions which are

Alpha particle emission \left \{ {{y=4} \atop {x=2}}He \right.
Beta particle emission \left \{ {{y=0} \atop {x=-1}}e \right.
gamma radiation \left \{ {{y=0} \atop {x=0}}γ \right.

in the problem the product formed after radiation was Pb-206. isotopes of lead include Pb-204, Pb-206, Pb-207, Pb-208. they all have atomic number 82. which means the radiation cannot be ∝ or β since both radiations will alter the atomic number of the parent nucleus.

Only gamma radiation with \left \{ {{y=0} \atop {x=0}}γ \right. will produce a Pb-206 of atomic number 82 and mass number 206 , since gamma ray have 0 mass and has 0 atomic number.equation is shown below

\left \{ {{y=206} \atop {x=82}}Pb\right ⇒ \left \{ {{y=206} \atop {x=82}}Pb\right + \left \{ {{y=0} \atop {x=0}}γ\right.

Thus the atomic symbol is \left \{ {{y=206} \atop {x=82}}Pb\right

La termodinámica es una ciencia que ayuda a comprender diferentes funciones y efectos que suceden a nuestro alrededor, entre est

Klio2033 [76]

Answer:

La pregunta no es clara, asi que voy a dar una breve descripicion de la termodinamica y alguno de los fenomenos que estudia

La termodinámica es la rama de la física que estudia los sistemas en equilibrio termodinámico (es decir, aquellos sistemas que no pueden sufrir un cambio espontáneo). Particularmente, la termodinámica estudia los procesos de flujo de calor (lo podemos ver en su nombre, dinámica del calor) y se relacionan estos cambios de energía con el trabajo que es posible obtener.

Entonces, por ejemplo, la termodinámica estudia como el hielo puede cambiar de fase (a medida que aumenta su temperatura) y convertirse en agua líquida.

La termodinámica también estudia como funcionan máquinas de calor, como motores de pistones, y el trabajo que estos son capaces de realizar.

Como ejemplo final, con la termodinámica podemos estudiar cosas tan complejas como equilibrio entre distintas fases (por ejemplo, el porqué podemos tener agua y hielo en equilibrio termodinámico, un ejemplo de esto son las superficies de ríos que se congelan mientras la parte inferior sigue siendo líquida)

Esos son, entre muchísimos otros, 3 posibles efectos que suceden a nuestro alrededor, y son estudiados por la termodinámica.

Which of the following is NOT an exothermic reaction?

nignag [31]

Answer:

a) dissolving sugar in water to form a mixture of sugar and water

Explanation:

exothermic reaction is reaction in which is heat is released during the reaction and endothermic reaction is a reaction in which heat is needed or required for the reaction to take place

all the options excluding option A) is exothermic as during the process of formation of bonds in oxidation, heat is released. rusting too is a slow form of oxidation and thus an exothermic reaction.

dissolving sugar in water is not exothermic reaction because their is no heat released. the sugar molecules simply disperses in the water molecules and form a solution.
