What element is being oxidized in the following redox reaction?

Chemistry
1 answer:
GrogVix [38]3 years ago
4 0

Answer:

The O is being oxidized, but at the same time, is being reducted.

Explanation:

H₂O₂(l) + ClO₂(aq) → ClO₂(aq) + O₂(g)

In this reaction, we have 4 compounds:

Hydrogen peroxide

Chlorine dioxide (twice)

Oxygen

In both dioxide, the Cl acts with +4 in oxidation state; the oxygen acts with -2.

Oxgen in ground state has 0, as oxidation number.

In peroxide, the H acts with +1 but  the oxygen acts with -1.

Peroxide is making the oxidation number from the O in the ClO₂, to decrease (reduction) and to increase in the O, at the ground state.

Hydrogen peroxide is a good reducing and oxidizing agent at the same time.

Answer:

Keq = 0.217

Explanation:

Let's determine the equilibrium reaction.

In gaseous state, water vapor can be decomposed to hydrogen and oxygen and this is a reversible reaction.

2H₂(g)  + O₂(g)  ⇄  2H₂O (g)         Keq

Let's make the expression for the equilibrium constant

Products / Reactants

We elevate the concentrations, to the stoichiometry coefficients.

Keq = [H₂O]² / [O₂] . [H₂]²

Keq = 0.250² / 0.8 . 0.6² =  0.217

Why reaction between phosphorus and oxygen produces four atoms of phosphorus and five atoms of oxygen
andreev551 [17]

Answer:

Reaction between an oxygen and  a phosphorus will produce oxides of phosphorus.

Explanation:

Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom  interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.

Explain how Beer’s law can be applied in food, drug or medical testing
KonstantinChe [14]
<h2>Answer with explanation:</h2>

<em><u>Beer's Law is described as if a light passes from a solution, the concentration of the solution is directly proportional to the  absorbance of light by that solution.</u></em>

Every element has a definite of absorbance of light.

In the testing of food, drugs or in medical testing, the light is passed from the sample.

Them transmitted light from these samples are measured. The difference between target light amount and transmitted light is the amount of absorbed light.

From this absorbed light value, we can identify an element in sample and its quantity.

Spectrophometry is based on this law.
