oxygen, is determined by the difference in its partial pressures between locations. Partial PRESSURE is the pressure a GAS EXERTS independent of others in a mixture. For example, oxygen makes up about 21% of the GASES in the atmospher

If it's a saturated SOLUTION and you STARTED decreasing TEMPERATURE then degree of saturation will DECREASE you can see sugar PARTICLES settling at the bottom

It's H2O GEOMETRIC...

A CHEMIST uses BIOCHEMISTRY branch of CHEMISTRY to determine the composition of the SUBSTANCE and to determine their mass.

Ammonium CHLORIDE decomposes readily when HEATED, but condenses in the cooler area at the top of the test tube. This is a reversible reaction, where the ammonium chloride decomposes into the gases AMMONIA (NH3) and hydrogen chloride (HCl).

The major use of sulfuric acid is in the production of FERTILIZERS, e.g., superphosphate of lime and AMMONIUM sulfate. It is WIDELY used in the manufacture of chemicals, e.g., in making hydrochloric acid, NITRIC acid, sulfate salts, synthetic detergents, dyes and pigments, explosives, and drugs.

NaOH is a strong base, so similarly, it fully DISSOCIATES to Na+ and OH-, therefore 1M NaOH produces 1M of OH-. In this case there are a few WAY to find the pH. The way I always did it is using the assumption that pH + pOH = 14 (this comes from the assumption of the water constant being 10e-14)

Therefore, for NaOH, pOH=-log[OH-] = -log1 = 0 so pH = 14 - pOH = 14 - 0 = 14

Pie bond = 7
Sigma bond = 24 + 3 - 1 = 26

Equivalent MASS = 78 /3 = 26 so normality = 78/26×2= 1.5 N

3Ca +N2 .......Ca3n2
it is the BALANCE EQUATION.

PLZ ASK the COMPLETE QUESTION........

While doing cooking, generally we add SALT to vegetables ( CONTAINS water). 
Adding salt, makes the concentration of salt higher in outside membrane of vegetables than in inside. ( more salt, less water) 

As a RESULT, due the process of OSMOSIS, water from vegetables comes outside making it softer and helps in FASTER cooking.

The RATIO of SOLUTION is. 1:8

this MEANS that they ALWAYS be in same PROPORTION

The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride. ... Usually the process is CONDUCTED on a BRINE (an aqueous solution of NaCl), in which CASE NAOH, hydrogen, and CHLORINE gives....

Substances that give IONS when dissolved in WATER are calledelectrolytes. They can be divided intoacids, bases, and SALTS, because they all give ions when dissolved in water.
That's why acid as well as BASICS considered as ELECTROLYTE...

Here is your ANSWER in this PICTURE

The ANSWER is BENZENE

The INCREASING order of the boiming POINTS of the
above GASES is : Nitrogen (lowest) Argon Oxygen
Carbon dioxide. Therefore, Carbon dioxide forms
the liquid FIRST as the air is cooled and nitrogen
forms the liquid in the last......

( iii 1 mol of H2O is the answer which I THINK. If it is RIGHT so PLEASE mark the answer as brain list.

The MINIMUM quantity of energy which is required to REMOVE an ELECTRON to INFINITY from the surface of a given solid, usually a metal is called work function.

Since N2 CONTAINS triple bond its ENTHALPY is very high HENCE it do not REACT at ROOM temperature

An ACID is something that DONATES hydrogen ions. For example, HCL DISSOCIATES readily to form H+ and Cl-.

Glucose and ethanol are not considered acidic because although they have hydrogen, their hydrogens do not dissociate easily.

Cs+2 because it is CLOSER to OCTET RULE

as it is a WEAK acid ... it does not forms HYDRONIUM ions on DILUTION with water , THUS CONDUCTIVITY decreases

hope it helps
