1)Combination REACTION:The reaction in which TWO elements react TOGETHER to FORM a single substance. example:C+O2---------- CO2
2) Decomposition reaction:The reaction in which a substance break down to form two elements is called decomposition reaction.
example :H2O ___electricity ___ H2+O2
3)Displacement reaction : The reaction in which highly reactive element displaces low reactive element from its Salt solution.
example :CuSO4+Zn______ ZnSO4+Cu
4) Double displacement reaction : The reaction in which REACTANT exchange their ions.
example :BaCl2+Na2SO4-----------BaSO4+NaCl

In nucleophilic alky substitution resonating structure is not more and due to these COMPOUND is UNSTABLE but in ARYL or BENZENE resonating is circulate complete and transfer electrone ortho META and para positions due to these structure is more stable

Answer : a COMPOUND that doesn't CONTAIN CARBON is inorganic compound as opposed to an ORGANIC compound, which CONTAINS carbon and hydrogen....

In a chemical reaction, SUBSTANCES (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can't change one element into another in a chemical reaction — that happens in nuclear reactions.

The substances that result from this RECOMBINATION of atoms are called the products of the reaction. When chemical reactions are written down, the reactants are written on the left side, in a similar manner to a math equation; one reactant plus another.

The terms reactant and PRODUCT can be USED to describe constituents of individual enzymatic reactions or entire METABOLIC pathways. Reactants (or 'substrates') are the starting materials for a reaction, In the generic reaction shown below, A and B are the reactants. C and D are the products.

Because during other SEASONS the POT is warm

it is ALSO because it is MADE out of CLAY

1.92×10^23 is the ANSWER

K₂SO₄.Al₂(SO₄)₃.24H₂O is the formula of Potash Alum.

= 2(39) + (32) + 4(16) + 2(27) + 3(32) + 12(16) + 24(18)

= 948 grams

Thus, the molecular weight of Potash alum is 948 grams

Hope it helps!!

Convential source of ENERGY usually include FOSSIL FUELS like COAL natural gas and oil.

Non Convential source include solar power ,WIND power,BIOGAS,tidal power rec.

The solution of sugar in WATER is HOMOGENOUS mixture because the sugar which is MIXED in water will dissolve completely and will DISAPPEAR

Minerals are matter of definite structure, physical PROPERTIES, and chemical composition that is FOUND on the ground. EG: natural gas, petroleum, gold, leaf, copper

Thank you for this question. Please find the answer below:

Removal of carbon PARTICLES from air INVOLVES the Principle of ELECTROPHORESIS.

ANSWER:

EMULSION Types. There are two basic types of EMULSIONS: oil-in-water (O/W) and water-in-oil (W/O). These emulsions are exactly what they sound like, as pictured below. In every emulsion there is a continuous phase that suspends the droplets of the other element which is called the dispersed phase.

Combustion Of Hydrocarbons : Alkanes. ... Combustion or burning is a high temperature exothermic reaction. It happens between a fuel and oxygen (oxidant), GIVING out gaseous PRODUCTS, also termed as smoke. ALKANE is referred to as a saturated open CHAIN hydrocarbon consisting of carbon-carbon single bonds.

The cell's resting membrane potential is the electric potential of the cell, and EXISTS as a result of ions MOVING into and out of the cell. This video covers the definition of resting membrane potential, as WELL as how to calculate it USING the Nernst equation.

Evaporate water from the copper sulphate solution so as to GET a saturated solution. Cover the solution with a filter paper and leave it undisturbed at room temperature to cool SLOWLY for a day. You will obtain the crystals of copper sulphate in the china DISH. The crystallisation method is used to purify solids.

Full form of CNG is Compressed Natural GAS..Compressed natural gas (CNG) (methane stored at HIGH pressure) is a fuel which can be used in PLACE of GASOLINE (petrol), Diesel fuel and propane/LPG. CNG combustion PRODUCES fewer undesirable gases than the fuels mentioned above...!

Some properties that nylon makes it a useful synthetic fibre are as follows first it is cheaper DURABLE all HUMAN beings second it is very strong and do not TWINKLE EASILY or it's SHINES does not remains for a longer period of time

⇒They shrink when you wash them in warm water.

NATURAL FIBERS like eg..cotton are only shrinking.

⇒ because they are RETURNING to their natural size. During the fabric-making

PROCESS, fibers are spun and drawn in order to make thread, which is then

used to produce your clothes.

Plasma is an electrically neutral medium of unbound positive and NEGATIVE particles (i.e. the overall charge of a plasma is roughly zero). It is IMPORTANT to note that although the particles are unbound, they are not ‘free’ in the sense of not experiencing forces. When a charged particle moves, it generates an electric current with magnetic FIELDS; in plasma, the movement of a charged particle affects and is affected by the general field created by the movement of other charges.

NEUTRON star is the collapsed core of a large (10–29 solar masses) star. Neutron stars are the smallest and densest stars known to exist.1 With a radius on the order of 10 km, they can, however, have a mass of about twice that of the Sun. They result from the supernova explosion of a massive star, combined with GRAVITATIONAL collapse, that compresses the core past the white dwarf star density to that of atomic nuclei.
I think it's help U

Hey mate!!!

BLEACHING powder is a yellowish WHITE powder with a strong smell of chlorine. When exposed to air, bleaching powder gives a smell of chlorine. This is because bleaching powder reacts withcarbon dioxide from the atmosphere to produce CALCIUM carbonate and chlorine.

It is because their valency changes




like iron



when is FERROUS OXIDE
has a valency of 2


but as FERRIC oxide it has valency of 3
