In SN1 REACTION, carbocation is formed. So a polar solvent is NECESSARY to stabilize the INTERMEDIATE. The MEDIUM with high dielectric constant STABILIZES the carbocation more. SN2 reaction doesn't involve charges.

When STEAM is passed on red-hot iron,
2Fe(s) + 3H2O(g) ———> Fe2O3 + 3H2(g)
Fe2O3 is FERROUS oxide.
Colour :- (Green).

And
Be my follower if POSSIBLE.

I HOPE that you UNDERSTAND

The ELECTRODE CONNECTED to the NEGATIVE TERMINAL of of battery is called cathode

Hope it is useful

Mark as BRAINLIEST

ANSWER:

none.

Explanation:

they have equal number of atoms SINCE masses are the same

the answer is the THING that no one knows just the people ask no one REPLY so dont ask the QUESTIONS

Periscope is a DEVICE to see HIDDEN corners.

The formula of ETHANE is C2H6. Where C-C(1 COVALENT bond)  and C-H( 6 covalent bonds ) and covalent bonds re formed between two non-metallic elements. If we draw the structure of ethane we ll find that they re SHARING ELECTRON and there re seven cobalent bonds.

hope it helps.....

Answer is in following..



☞The Hinsberg TEST, which candistinguish primary, secondary, and TERTIARY amines, is BASED upon sulfonamide formation.

☞If the sulfonamide that forms dissolves in aqueous sodium hydroxide SOLUTION, it is a primary AMINE.

☞If the sulfonamide is insoluble in aqueous sodium hydroxide, it is a secondary amine.




hope this helped u plz mark me as brainlist or follow me..

for EMPIRICAL formula add all the quantity of ELEMENTS and for molecular formula MULTIPLY all the molecular MASSES

It is ACCORDING to AVOGADRO's LAW

So , the molecular MASS of NACL is 23 + 35.5 =58.5 . NaCl OCCUPIES fcc structure i.e 4 atoms will constitute 1 unit cell.

Benzenoid are those compounds which are DERIVED from benzene THUS SHOW complete delocalisation in the ring..non benzenoid are not derived from benzene ring but shows proper CONJUGATION nd follows huckel rule.

Hey mate here is your answer》》

In a displacement reaction, a more reactive metal can DISPLACE a less reactive metal from its salt solution. The elements POTASSIUM, SODIUM, lithium and calcium are very reactive and they react with cold water to produce HYDROXIDES and hydrogen GAS. That is why each metal react to its own salt.

Each carbon atom in ethane forms four single bonds, one to each of three HYDROGEN atoms and one to the neighboring carbon atom. However, in some organic molecules, a carbon atom sharestwo or three pairs of ELECTRONS with another BONDED atom. If two electron pairs are shared, a double BOND exists.

Hydrolysis: Breaking of a compund using water.

Eg. NaCl + H2O ---> NaOH + HCl

Hydration: Addition of a water molecule to a compound

Eg. Hydration of ethene

..... C2H4 + H2O → CH3CH2OH

-

In both cases, water is required.

But hydration is an electrophilic addition reaction (to an alkene) so there is no splitting/cleavage of the ORIGINAL molecule . It merely involves adding a hydrogen atom and an -OH group to to unsaturated molecule where the C=C bond is located.

In hydrolysis, water is added to cleave/split a larger molecule into two SMALLER molecules , EXAMPLE using a water molecule to break an ester bond , amide bond, GLYCOLYTIC bond ,etc . Example hydrolysis of sucrose to glucose and FRUCTOSE by cleaving the glycolytic bond

Or hydrolysis of ethyl ethanoate an ester into ethanol (an alcohol) and ethanoic acid (a carboxylic acid) by breaking the ester linkage.

The PRODUCTS formed when Ethane burns in AIR with OXYGEN are CARBON doixide , water and carbon monoxide.

the equation is:

chemical equation:

C2H6 + 3O2 = CO2 + CO + 3H2O + Combustion

HOPE THIS HELPS!!!!

Which ONE is your QUESTION

The volume of kmno4 used. in the titration is CONSIDERED as 17 POINT 1 mlmolarity of kmno4 solution from the CHEMICAL equation. we can notice that 2 moles of kmno4 REACTS with 5 moles of oxalic acid molarity. of kmno4 into volume of kmno4 by molarity of oxalic acid into volume of oxalic.

It is a property of a substance DUE to which it allows heat and electricity to PASS through it. its SI unit is simen per meter (S/m) .
it increases with temp in silicon but decreases in copper with RISE in temp

The valency of an atom is equal to the NUMBER of electrons in the OUTER shell if that number is FOUR or less. OTHERWISE, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of electrons, you can easily calculate the valency.

Hey mate here is your answer》》

Three main types of formations in which mineral occurs are :

(i) Veins and lodes In igneous and metamorphic rocks MINERALS may occur in the CRACKS, crevices, faults or joints. Smaller occurrences are called veins and larger ones are called lodes.

(ii) Beds or Layers In sedimentary rocks, minerals occur in bed or layers. They are formed as a result of deposition, accumulation and concentration in HORIZONTAL strata, (layers)

(III) Placer Deposits Certain minerals occur as alluvial deposits in SANDS of valley floors and the base of hills as placer deposits.

The IUPAC NAME of COMPOUND is:
2-Pentene.

Fractional distillation is a powerful WAY of separating two or more miscible liquids. 

The separation is based on the boiling point differences of the components of the mixture, usually LESS than 25 ºC.  

Using a fractionating COLUMN which ALLOWS for repeated simple distillations two or more liquids can be successfully separated.

There is a vast VARIETY of compounds which we USE in EVERYDAY life but the FOUR of them are GIVEN below:
▪PRINTER INK
▪PLASTIC BAGS
▪SYNTHETIC FIBRES
▪FERTILIZERS

What's the QUESTION?

Syndiotactic polyacrylonitrile with 4 monomer units is attached in the word DOCUMENT. So please DOWNLOAD it and see how it goes.

We have the following and I happen if you get to learn more about I think you will be better placed because it is good if you have knowledge about these varieties and what they mean.

Tacticity GENERALLY refers to the regularity of the polymer having the geometric or spatial arrangement of molecules in a polymer CHAIN. in general, in a tactic, the direction is not ordered.

Isotactic, oh the other hand means every molecule is ALIGNED in the same direction.

Syndiotactic also implies that the direction of adjacent molecules alternates.

We have to FIND that how is Aniline obtained from Benzonitrile.

Kindly SEE the attachment. A complete reaction is shown in the attachment.

We have to treat Aniline with SODIUM NITRITE & HCl.

We must treat them at LOW temperatures.

This reaction gives us diazoniumchloride.

The diazoniumchloride reacts with CuCN and gives us Benzonitrile.

The key DIFFERENCE between ferromagnetism and antiferromagnetism is that ferromagnetism can be found in materials having their magnetic domains aligned into the same direction WHEREAS antiferromagnetism can be found in materials having their magnetic domains aligned in opposite directions.

A magnetic DOMAIN or an atomic moment is a region in which the magnetic fields of atoms are grouped TOGETHER and aligned. Ferromagnetic materials are attracted to an EXTERNAL magnetic field and have a net magnetic moment. But antiferromagnetic materials have a zero net magnetic moment
