Anode is the ELECTODE where oxidation take place. .

Always ..

In the cell .anode means that cathode where always oxidation take place. ..and cathode is !.........

Hope u will GET it ..

NAME Harshit

Here is in your answer____


Galvanic cell converts chemical energy into ELECTRICAL energy.Both the ELECTRODES are placed in a same container in the solution of molten electrolyte. Here the anode is negative and CATHODE is the positive electrode. The reaction at the anode is oxidation and that at the cathode is reduction.

Galvanic cells are batteries. The redox reaction in the battery always has a positive voltage due to DIFFERENT chemical species.

Concentration cells are batteries and discussed these after we covered the Nernst Equation. The redox reaction always has a positive voltage due to the same chemical species having different concentrations.

Those changes in which no NEW SUBSTANCES are FORMED are called PHYSICAL changes
ex =melting of ice
those substances in which new substances are formed are called CHEMICAL changes
ex=burning of paper

oxidation REACTION will OCCUR when 5% of ALKALINE potassium permaganate is ADDED to the ethanol.  the name of the compound formed is ethanoic acid(acetic acid). we can PERFORM the process of Esterification to identify this compound.  

Chemical property
METAL
they REACT with OXYGEN and FORM metal OXIDE

Similarity are: (i) Both lithium and magnesium are harder lighter than other ELEMENTS in the respective groups. (ii) Lithium and magnesium react slowly with WATER. Their oxides and HYDROXIDES are much less soluble and their hydroxides DECOMPOSE on heating.

here is UR ANSWER dude MAY be it helps U

Solution: The data given in the problem isP = 760mm of HG = 1 atm V = 500CM3 T =  270C T = 27+ 273 = 300 K R = 82.1 cm3 K-1mol-1 number of moles of hydrogen (n) = ? According to IDEAL gas equation PV= nRT n = PV/RT = 1 atm X 500 cm3 /82.1 cm3 K-1mol-1 X 300 K n = 0.023mol

BASICALLY IF YOU QUALIFIED IN STAGE FIRST THEN YOU HAVE SOME IDEA ABOUT THE QUESTION TREND OF NTSE .IT MAY HAVE CHANCE TO SELECT DO STAGE 2 BECAUSE THIS YEAR QUESTION ARE OF ANALYTICAL APPRAOCH

The LIMITATION of Rutherford MODEL of an atom was

Rutherford model said that electrons revolve around Preston's but this COLLIDED with the fact that if electron keeps on revolving then SOON will loose it's energy ,resulting in dieing of an atom that was not possible .

our UNIVERSE is a open system beacause
An open system can exchange both ENERGY and matter.

A CLOSED system can exchange only energy.

An isolated system cannot exchange ANYTHING.

DEAR friend,

carbon is used as a reducing AGENT while ELECTROLYSIS is the process which is used for reduction.

example of reduction with carbon-

ZnO+C-------->Zn+CO

example of electrolysis-

Al (aluminium in iron FORM)+ 3e ---------> Al (aluminium metal)

hope it helped,

plz follow.

Hiii here is your answer


(in chemistry) an atom or a molecule that has gained or LOST one or more of its PARTS (ELECTRONS) and so has a positive or negative ELECTRIC charge

This question is quite easy the information which has been given is that the OXIDATION number of A B C are + 2 + 5 and minus 2 respectively possible formula of the compound is given as shown below;

 A₃(BC₄)₂

I hope this very helpful to you.

This question just tests to know whether you are in a position to derive an equation given the oxidation states.

You can also be asked to GET oxidation STATE of a given compound.

Elevation is a colligative property.Colligative properties are dependent on no of particles.

In NaCl no of particles is 2 where as in BaCl2 it is 3 (1 Ba and 2Cl) so BaCl2 SHOWS more elevation than NaCl

A SOLID has a definite shape and volume. A liquid has a definite volume but it TAKES the shape of a container WHEREAS a gas fills the entire volume of a container. ... Thus, the two FORMS are different (liquid) phases of helium. At a definite temperature and PRESSURE, the two phases co-exist.

Lifestyle -- or a typical way of life, as health specialists often define it -- could AFFECT an individual's health and life expectancy. ... OBESITY also causes an individual to experience health problems and could lead to DISEASES and risky conditions INCLUDING high CHOLESTEROL, diabetes and heart disease

Thanks for asking the question.

Here's your answer

Generally when metals are TREATED with acids they give RISE to hydrogen gas. But HNO3(nitric acid) is a strong oxidising agent which no metal has the ability to displace hydrogen from it.

I Hope this answer helps you.

a metal salt is a COMPOUND formed when the hydrogen of an ACID is REPLACED by a metal.

Eg. SODIUM chloride, CALCIUM carbonate.

I hope this answer helps you.

Now, charge on Cl = -2, NH3 = 0, therefore, -2 charge on Cl and +2 charge on the coordination sphere is balanced by +4 charge on Pt.Thus, the oxidation state of Pt is +4



I hope this will HELP you

Two of the most COMMON compounds are ALUM, such as potassiumaluminum sulfate (KAl(SO4) 12H2O), and ALUMINUM OXIDE (Al2O3).

Mass of 1 ATOM = 2.65 × 10−23 G

Therefore, mass of 6.022 × 1023 atoms

= 2.65 × 10−23× 6.022 × 1023 g = 15.96 g ≈ 16 g mol−1

Therefore, the atomic mass of the element is 16 u. is your answer

35.04580 ± 0.00085 g/mol is the ANSWER

Redox reaction contains two TYPES of reaction

1. gaining of oxygen or loss of hydrogen

2. gaining of hydrogen or loss of oxygen

The % of B is 25%.

It is now known that the relation between the vapour density and the molecular mass of a compound or mixture is given as FOLLOWS:

M = 2 X VD

So, molecular mass of the mixture is 50 units.

Now, assuming that the % of B is x %, we can take % of A to be (100-x) %.

Substituting the equation of the mass relation with the assumed mass percentages, we FIND that the percentage of B COMES out to be 25%.

Molar CONDUCTIVITY of strong acids or electrolytes is not a FIXED constant or quantity. Rather, it depends on several FACTORS including the electrolytic concentration and SPECIFIC conductance of the electrolyte in question.

The RELATION between the following quantities can be expressed as follows:

Molar conductivity = (specific conductance) / (concentration)

As we can see, it is not a fixed constant quantity and can vary over a wide range of values.

Catemation is property of carbon due to which its atom can join with one ANOTHER to form long carbon CHAINS is called CATENATION. catenation means self linkingor
carbon has unique ability to form BONDS with other ATOMS of carbon giving rise to large molecules is known as catenation

It will be POSITIVE..
SINCE DELTA S>0 in an isolated SYSTEM.

When bee stings a person ,it injects an acidic liquid into the SKIN which causes pain and irritation.if the bee stings a person,then RUBBING a mild base LIKE baking soda solution on the stung area of the skin GIVES relief.

This is because being a base baking soda neutralises the acidic liquid injected by bee sting and cancels its effect.
