(3) H > 0; S >O Explanation:Endothermic reactions are those in which HEAT is absorbed by the SYSTEM and exothermic reactions are those in which heat is released by the system. for Endothermic reaction is positive and for Exothermic reaction is negative.Entropy is the measure of randomness or disorder of a system. If a system moves from  an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice VERSA. is positive when randomness increases and is negative when randomness decreases.For the given gaseous reaction:                                                 As the number of moles of products is more than the number of moles of reactants, the entropy is INCREASING,   is positive for endothermic reaction.Thus H > 0 and  S > 0.

Explanation:Hence chlorobenzene is more electronegative than cyclohexyl chloride. THEREFORE, the DENSITY of electrons C-Cl bond at CHLORINE atom is less in chlorobenzene than cyclohexyl chloride. Due to this polarity of the C-Cl bond decreases and hence dipole moment of chlorobenzene is lower than cyclohexyl chloride.

Sodium hydrogen carbonate (also KNOWN as sodium bicarbonate or bicarbonate of SODA) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down, forming sodium carbonate, WATER and carbon dioxide. This type of REACTION is CALLED a thermal decomposition.

Explanation:There is a vast difference between USING the same reagent in two different SOLVENTS as in here. BASICALLY, when we use Alcoholic potassium hydroxide i.e, KOH as a reagent, the negative part of the reagent, that is OH- it acts a a base and abstracts the BETA Hydrogen from the saturated substrate( alkyl hallide) present and trasforms it to an alkene in the product, thereby undergoing Elimination reactio

In CASE of HALOGENS INDUCTIVE EFFECT DOMINATES mesomeric effect..

tal is exposed to the air, moist water and ACID etc. for some time the THIN layer of OXIDE is formed is called CORROSION Oiling Painting Greasing Galvanisation Tin or CHROMIUM plating Alloying

Heya MATE......This is a REVERSIBLE reaction because HI is very strong reducing agent. When reaction is first CARRIED out in forward direction HI FORMED tries to reduce CH3l and the iodine in HI tries to oxide itself from oxidation state-1 from 0 and thus the reaction go in backward direction.Hope it helps.......

I don't KNOW SORRY sorry

a) increasesExplanation:Valency just REFERS to the electrons in the OUTERMOST energy levels of the atom that are available for chemical bonding. The basic idea is this: as you move across the PERIODIC table, the number of valence electrons increase. You can see this for yourself.Hope it helps... Mark as branliest...

i think so it is CORRECT answer Explanation:VALUE of x is 3

sed WASHING purpose in laundry.It is used for softening hard water.It is used In the industries for the manufacturing of GLASS , SOAP and PAPER etc.

The answer of the c SUB QUESTION is Al2O3Explanation:Aluminium oxide is one of the most acidic AMPHOTERIC oxides and THUS is a good EXAMPLE.

dq/dtExplanation:rate of flow of charge in given INTERVAL of TIME

rule states that a compound with low positive CHARGE, large CATION and SMALL anion has ionic BOND where as a compound with high positive charge, small cation and large anion are covalently bonded. For high charge, small cation will have more polarizing power.

Polarizability can be defined as the MEASURING ability of how electron clouds can be changed ( distorted ) by an electric field. In general, this function happens with an electron cloud which is usually connected with either atoms, molecules or ions. EXPLANATION:In specifically ionic Polarizability, this happens because of the following reason, - Cause: Within an ionic crystal when, certain displacements TAKE PLACE among the + and - ions. -Tip: It happens in the case or relative displacements.

It can be explained by USING the aufbau PRINCIPAL. It explains lower the energy of the orbital will fill first with the ELECTRONS. Energy can be CALCULATED by using =n+L VALUE.

I THIN the CORRECT ANSWER of this QUESTION is C

wattPLZ MARK as brainliest.Follow me.#RISHABH WRITES

yesExplanation:because it is more electronegative than chlorine. INFACT MORE AMONG ALL.so LESS TENDENCY to GIVE ELECTRON

will HELPS you :)PLEASE MARK me as BRAINLIEST

Because chlorine is bigger in size hence less ENERGY is LIBERATED That's why chlorine having good tendency of ELECTRON affinity than fluorine

When milk changes into curd it's ph is DECREASED as the curd contain LACTIC ACID and acid has a ph LESS than ph of milk. So ph decreased from milk to curd.hope you like it!!MARK as brainliest√

yesExplanation:because LIKE DISSOLVES likethat MEANS POLAR dissolves polarand NON polar dissolves non polar

yesExplanation:because their ORBITALS COMPLETED.

if a GIVEN solution is ACIDIC it pH GOES below 7

ays are BARE helium nucleiBeta rays are electronsGamma rays are lethal very HIGH frequency electromagnetic radiation.The energies of alpha and Beta rays are kinetic energy which can be varied according to the experimental conditions.But the energy of Gamma rays are due to intrinsic frequency VALUE . It is same for each every PHOTON emitted in that particular ray.Alpha and Beta particles can have different energies even in the same condition!!!!

The COMPRESSIBILITY factor (Z), also known as the compression factor, is a useful thermodynamic property for modifying the ideal gas law to ACCOUNT for the REAL gas behavior.[1] In general, DEVIATION from ideal behavior becomes more significant the closer a gas is to a phase change, the lower the temperature or the.· The compressibility factor for an ideal gas is ONE.

Hi mark it as the brainliestExplanation: The separation process is a method that converts a mixture or solution of chemical SUBSTANCES into TWO or more distinct product mixtures. At LEAST one of RESULTS of the separation is enriched in one or more of the source mixture's constituents.

What is the QUESTION here.... I don't KNOW the question

HiExplanation:ACETYLENE is capable of producing the hottest flame thus USED in welding and cutting process in industries. Also, the chemistry of propylene results in better heat transfer properties than acetylene which means you can increase productivity by producing faster cuts. When considering which fuel gas should be used, safety is at the TOP of the list. Propylene is generally CONSIDERED a safer because it is a more stable gas.
