methanol and water are examples of solutionsshowing positive deviation from Raoult’s Law.

hence it is non-ideal solution.

Anilineis typical of aromatic primary amines - where the -NH2 group is attached directly to a benzene ring. These are very much weaker basesthanammonia.Anilineis morebasic than ethylaminebecause of resonance. ... Hence,anilinelooses proton more readilythantheethylamine.

Oxidation number of Mn in KMnO4 is (-7)

Here+1+x+(-2)*4= 0x= +7so oxidation number is +7

+7 is oxidation number O is -2 O. N. K is +1 O. N.

An orbital is a mathematicalfunctioncalled awave functionthat describes an electron in an atom. ...Radial wave functionsfor a given atom depend only upon the distance, r from the nucleus. Angularwave functionsdepend only upon direction, and, in effect, describe the shape of an orbital.

both oxidation number and valency are different

yes both oxidation and valency are different

Redox reactions are the reactions in which the oxidation and reduction process are carried out simultaneously i.e. one reactant is getting reduced by gaining of electrons while the other gets oxidized by loosing of electrons.

Redox reactions can be defined as the reactions in which one of the reactantgains oxygen or losshydrogen gets oxidized and the other substance gains hydrogen or lossoxygen getreduced.

Oxidation is thegainof oxygen.

Reduction is thelossof oxygen.

oxidation is the gain of oxygenReducation is the loss of oxygen

oxidation means either gaining oxygen or losing hydrogen and reduction means either gaining hydrogen or losing oxygen

oxidation means addition of oxygen or electronegetive atom and reduction means addition of hydrogen or electopositive atom

oxidation in which O atom gain and H atom lose

Reduction in which H atom gain and O atom lose

Redox (short for reduction–oxidation reaction) (pronunciation: /ˈrɛdɒks/ redoks or /ˈriːdɒks/ reedoks) is a chemical reaction in which the oxidation states of atoms are changed. Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes. Redox reactions include all chemical reactions in which atoms have their oxidation state changed; in general, redox reactions involve the transfer of electrons between chemical species. The chemical species from which the electron is stripped is said to have been oxidized, while the chemical species to which the electron is added is said to have been reduced. It can be explained in simple terms:

Oxidation is the loss of electrons or an increase in oxidation state by a molecule, atom, or ion.Reduction is the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion.As an example, during the combustion of wood, oxygen from the air is reduced, gaining electrons from carbon which is oxidized.[3] Although oxidation reactions are commonly associated with the formation of oxides from oxygen molecules, oxygen is not necessarily included in such reactions, as other chemical species can serve the same function.

PLEASE HIT THE LIKE BUTTON

This is anoxidation-reduction(redox reaction)Fe will give 2 electrons which will be accepted by sulphur to make an electrovalent bond. Hence iron is oxidized and sulphur is reduced.

2 chloro 3 bromo butanoic acid

d is answer i think

Ans :- Reductionis chemicalreactionthat involves the gaining of electrons by one of the atoms involved in thereaction.The term refers to the element that accepts electrons, as the oxidation state of the element that gains electrons is lowered.

In that example, the iron is oxidized and the oxygen isreduced.

Ans :- Roastingis a process in metallurgy in which a sulfide ore is heated in air. The process may convert a metal sulfide to a metal oxide or to a free metal.Example:RoastingZnS may yield ZnO;roastingHgS may yield free Hg metal.

3-ehtyl-4-methylhexane

thanks

option B is correct..........

right now but kashmir there a reason the same problem and amira of a sudden of this

it is solved already

Ans :- Compounds between Metals and Nonmetals (Cation and Anion) Compounds made of a metal and nonmetal are commonly known as Ionic Compounds, where the compound name has an ending of –ide. Cations havepositivecharges while anions havenegativecharges.

A modern statement is:Avogadro's lawstates that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Boyle's Law is a relationship between pressure and volume.

P1V1 = P2V2

In this relationship, pressure and volume have an inverse relationship when temperature is held constant. If there is a decrease in the volume there is less space for molecules to move and therefore they collide more often, increasing the pressure. If there is an increase in the volume the molecules have more space to move, collisions happen less often and the pressure is decreased.

One 2s orbital and Two 2p orbitals undergo sp2 hybridisation having 3 sp2 hybridised orbitals. Overlap of hybrid orbitals with 2p orbitals of chlorine.

(b) is correct option

Both assertion and assertion are true but reason is not the correct explanation of assertion.

In osmotic pressure method, pressure is measured at room temperature and instead of molality, molarity of the solution is used. It is preferred for the macromolecules like proteins as they are unstable at high temperature and polymers have poor solubility. Also, due to their high molecular mass, the only colligative property which has a measurable magnitude is osmotic pressure. Therefore, osmotic pressure method is preferred.

1. Natural polymers, Synthetic polymers, Semi-synthetic polymers

2. Vulcanization is a chemical process used to harden rubber.

Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other rubbers via various means.

In chemistry and biology across-linkis a bond that links onepolymerchain to another. These links may take the form of covalent bonds or ionic bonds and thepolymerscan be either syntheticpolymersor naturalpolymers(such as proteins).eg. Bakelite , melamine

thermosetting polymers have less force of attrection.........so a is your answer

Option (a) thermosetting polymers are correct as, they have the weakest interparticle forces of attraction present in them.

If there is a radial node. the the value of the function should be 0.

=> for that (2- rₒ/aₒ) = 0=> rₒ/aₒ = 2 => rₒ = 2aₒ
