can you explian me about the oxidixer

Answers

Answer 1

Explanation:

An oxidizer is a substance that facilitates oxidation, a chemical reaction where a substance loses electrons. It is also called an oxidizing agent or oxidant. Oxidizers are commonly used in combustion reactions, supporting the burning of fuels by providing oxygen. Examples of oxidizers include oxygen, chlorine, hydrogen peroxide, and potassium permanganate. They have applications in combustion, chemical synthesis, bleaching, rocket propellants, and cleaning. Oxidizers can be highly reactive and require proper handling and safety precautions.

Express your answer as a chemical equation.

Answers

A) The chemical equation for the reaction is [tex]Cl_2(aq) + 2KBr(aq)[/tex] ⟶ [tex]2KCl(aq) + Br_2(aq)[/tex]

B)No reaction occurs when elemental iodine is mixed with lithium chloride. [tex]I_2(aq) + 2LiCl(aq)[/tex]⟶ No Reaction

A) To predict whether a reaction will occur when elemental chlorine ([tex]Cl_2[/tex]) and potassium bromide (KBr) are mixed, we can refer to the activity series for the halogens. According to the activity series, chlorine is more reactive than bromine. Therefore, chlorine can displace bromine from its compounds.

The chemical equation for the reaction between chlorine and potassium bromide can be written as:

[tex]Cl_2(aq) + 2KBr(aq)[/tex] ⟶ [tex]2KCl(aq) + Br_2(aq)[/tex]

In this reaction, chlorine displaces bromine from potassium bromide, resulting in the formation of potassium chloride and elemental bromine.

B) Similarly, to predict whether a reaction will occur when elemental iodine ([tex]l_2[/tex]) and lithium chloride (LiCl) are mixed, we can refer to the activity series. In the halogen activity series, iodine is less reactive than chlorine and bromine. Therefore, it is less likely for iodine to displace chlorine or bromine from their compounds.

The chemical equation for the reaction between iodine and lithium chloride can be written as:

[tex]I_2(aq) + 2LiCl(aq)[/tex]⟶ No Reaction

No reaction occurs because iodine is less reactive than chlorine, and lithium chloride does not react with iodine under these conditions.

Therefore, when elemental chlorine is mixed with potassium bromide, a reaction occurs and chlorine displaces bromine. On the other hand, no reaction occurs when elemental iodine is mixed with lithium chloride.

The OH concentration in an aqueous solution at 25 °C is 3.3 x 10³.
What is [H*]?

Answers

The concentration of hydroxide ions ([OH-]) and the concentration of hydronium ions ([H+]) are related in an aqueous solution by the equation [H+][OH-] = 1.0 x 10^-14 at 25 °C .The concentration of hydronium ions ([H+]) in the aqueous solution at 25 °C is approximately 3.03 x 10^-18.

Given that [OH-] is 3.3 x 10^3, we can substitute this value into the equation as follows:

[H+][3.3 x 10^3] = 1.0 x 10^-14

Dividing both sides of the equation by 3.3 x 10^3, we get:

[H+] = (1.0 x 10^-14) / (3.3 x 10^3)

Simplifying the expression, we have:

[H+] ≈ 3.03 x 10^-18

In summary, at 25 °C, an aqueous solution with an OH- concentration of 3.3 x 10^3 has a hydronium ion concentration of approximately 3.03 x 10^-18. The hydronium ion concentration is determined by the equilibrium constant for water dissociation and is inversely proportional to the hydroxide ion concentration. The two concentrations are related through the equation [H+][OH-] = 1.0 x 10^-14.
