Why must oxidation be accompanied by a reduction?

Chemistry
2 answers:
Crazy boy [7]3 years ago

Answer:

A

Explanation:

because the species being oxidized shares electrons with the species that is reduced.making the oxidized element positively charged and the reduced element negatively charged.

A when sulfuric acid is added to sirie, hydrager
irga5000 [103]

Sulfuric acid is prepared industrially by means of the response of water with sulfur trioxide which in turn is made by way of a chemical combination of sulfur dioxide and oxygen both by way of the touch system or the chamber system.

                         H2SO4 (l) H2O (g) + SO3 (g).

The reaction is highly exothermic as an enormous amount of heat is liberated.

The usual approach is to dilute the sulfur trioxide in sulphuric acid. This produces oleum. SO3 (g) + H2SO4 → H2S2O7 (1) Oleum can be in addition diluted in water to acquire concentrated sulphuric acid.

An acid catalyst is added to protonate the carbonyl carbon. How does this catalyze the response, robust acid catalysts catalyze the hydrolysis and transesterification of esters which enables the mechanism with a view to boom the electrophilicity of the carbonyl carbon to assist protonate the carbonyl oxygen.

Part A
inysia [295]

Pressure of the gas inside the container is 662.59 torr.

<h3>What is ideal gas law?</h3>

The ideal gas law (PV = nRT) connects the macroscopic characteristics of ideal gases. An ideal gas is one in which the particles are both non-repellent and non-attractive to one another (have no volume).

The general law of ideal gas can be applied here: PV is equal to nRT, where P is the gas pressure in atm.

V is the number of moles of the gas in a mole, and n is the volume of the gas in L. R is the universal gas constant. T is the temperature(Kelvin) of the gas.

If P and T are different values and n and V are constants, then

(P₁T₂) = (P₂T₁).

P₁ = 735 torr, T₁ = 29°C + 273 = 302 K,

P₂ = ??? torr, ​T₂ = 62°C + 273 = 335 K.

∴ P₂ = (P₁T₂)/(P₁) = (735 torr)(302 K)/(335 K) = 662.59 torr.

Stereoisomers that are not mirror images of each are ____________ . The chemical and physical properties of two ____________ are
Tanzania [10]

Answer:

Stereoisomers that are not mirror images of each are <u>diasteroisomer</u> . The chemical and physical properties of two <u>diasteroisomers</u> are different. Isomers that differ only in the way atoms are oriented in space are <u>Stereoisomers</u> . Achiral compounds that contain tetrahedral stereogenic centers are <u>meso</u> <u>isomers</u> . Isomers that differ in the way the atoms are connected to each other are <u>structural</u> <u>isomer</u> . Stereoisomers that are nonsuperimposable mirror images of each other are <u>enantiomers</u> . The chemical and physical properties of two <u>enantiomers</u> are identical except in their interaction with chiral substances.

Explanation:

Diasteroisomers are differentiated by the spatial arrangement of atoms, but they are not specular images so they are not enantiomers. In order for two molecules to be diastereoisomers, they must have at least two chiral centers. In one of the centers the substituents are arranged equally in both molecules and in the other they must change.

Enantiomers are specular images but are not superimposable. They have the ability to rotate the polarized light plane

The stereoisomers present the same molecular formula but different spatial rearrangement between their atoms, we can mention the cis and trans isomers where the cis isomers are on the same side of the plane and the trans isomers on opposite sides. They are also known as geometric isomers.

Meso compounds always have more than one asymmetric center and are aquiral. They are distinguished because they present a plane of symmetry.

Structural isomers are those that have different connectivity between their atoms. We can differentiate, for example, metoximethane from ethanol. They will always have the same molecular formula.

The Ksp of cobalt(II) hydroxide, Co(OH)2, is 5.92 × 10-15. Calculate the molar solubility of this compound.
Dima020 [189]
The Ksp of cobalt(II) hydroxide is equal to [OH-]2[Co2+]=5.92*10-15. And [OH-]=2[Co2+]=2*[Co(OH)2](dissolved). So the molar solubility of this compound is 1.14*10-5 M.
