There are some methods use for identification the organic compounds.

a- The systematic NOTE the change of PERMANGANATE ᴄᴏʟᴏʀ.

identify the FUNCTIONAL GROUPS of compounds.

Potassium permanganate has a molar mass of 158.034(1) G mol−1, and reacts with FIVE moles of electrons PER mole of potassium permanganate, so its equivalent weight is 158.034(1) g mol−1/5 eq mol−1 = 31.6068(3) g eq−1....☺️☺️

Partial combustion OCCURS in the lower i.e. BLUE ZONE
complete combustion in UPPER
i.e. YELLOW zone

Iodine is odd SINCE all other are gases in their molecular STATES

The chemical BONDING is an ATTRACTION between ATOM molecules such as hydrogen,carbon,WATER,ethylene


HOPE you will make me brainiest please

Because it is not DANGEROUS. it does not HARM other PEOPLE .so it can be transported to homes directly.as this is eco friendly GAS. compressed natural gas

No. Of ATOMS in 1 MOL of TETRAATOMIC GAS = 6.023 ×10^23 ×4
THEREFORE, 0.1 mol will have =4×0.1×6.023×10^23 atoms

To find the PERCENTAGE of PURITY of magnesium carbonate

MgCO3 = mass of MG + mass of c + mass of o ×3 / 100

hybridisation

H=1/2(V+M+C-A)

V=no.of electrons in the VALENCE SHELL of the CENTRAL atom

m=no.of monovalent bond

c=cation a=anion

Eg: METHANE CH4

h=1/2(4+4-+0-00

=8/2 =4

sp3 hybridisation

The REASON why non-metals do not displace hydrogen from dilute acids is because unlike metals, non-metals do not have a tendency to lose ELECTRONS but to gain electrons. Metals have a tendency to lose electrons. These electrons, which are readily lost by reactive metals like sodium, potassium etc are accepted by hydrogen ions of the acids, reducing them to hydrogen GAS (H2). 2 H+ + 2E- → H2 However, non-metals do not lose electrons readily, because of which they do not displace hydrogen from acids. ANOTHER important point to note is that not all metals will displace hydrogen from acids. Only those metals which are reactive than hydrogen will displace H2 from acids.

They are typically heat-resistant and either LIQUID or rubber-like, and are used in SEALANTS, adhesives, lubricants, medicine, COOKING utensils, and thermal and electrical insulation. Some common FORMS include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk.

noble GASES

fully COMPLETE octet

stable most in the period

require highest ionization energy

and vice versa for p BLOCK elements

Scientific NOTATION is a way of writing numbers that is often used by scientists and MATHEMATICIANS to make it easier to write LARGE and small numbers. A number that is WRITTEN in scientific notation has several properties that make it very USEFUL to local scientists. It makes very large numbers into smaller numbers using decimals and exponents.

Application Of SOLUBILITY-product To Precipitation

Solubility product is the product of CONCENTRATIONS of ions.


Equilibrium concentration, 

And solubility product, 

• When solubility product is larger than the ionic product, , then a unsaturated solution is FORMED and no precipitate will be formed by the addition of more SOLUTE.

• When solubility product is smaller than ionic product then a super saturated solution will be formed and and excess of the solute will form precipitate.

• When solubility product is equal to the ionic product, then the solution will be saturated and further addition of solute will form more precipitates.

Sea- water and lake contains sodium chloride. This sodium chloride is impure which can be purified on the basis of common ion effect. Sodium chloride dissociates into its component ions. When this NaCl solution is passed through HCl gas then



The presence of common ion, Cl- the dissociation of NaCl is lowered and ionic product BECOMES greater than solubility product and it forms precipitate.

The BEST WAY is DISTILLATION followed by crystalization.

alkynes are TRIPLY bonded carbon BONDS in a COMPOUND having three bonds in three perpendicular planes

alkenes are dounbly bonded carbon bonds in a compound having two bonds (ONE in the PLANE and one out of the plane)

When NAOH and KCl react, they FORM KOH and NaCl. Such TYPE of reactions are called double displacement reactions.

A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (CATION) and the negative ions (anion) of the two reactants switch places, forming two new compound

if ring is absent it is no BENZENE anymore but BECOMES simple cycloalkane named CYCLOHEXANE

Fe3+=1s2 2s2 2p6 3S2 3p6 4S2 3d3
Cr3+=1s2 2s2 2p6 3s2 3p6 4s2 3d1
Pb2+= [XE] 6s2 4f14 5d10
Pb4+= [Xe] 4f14 5d10
O2= 1s2 2s2 2p6 3s2 3P4

Quantity of salt = 2.5g

Quantity of WATER = 50g

Molality = (Quantity of SOLUTE /Quantity of Solvent) × 1000

= (2.5 ÷ 50) × 1000

= 50 m

∴ Concentration of this SOLUTION is 50 M..

Potential RESOURCES are those who may be used in future but not now . eg - URANIUM of ladakh
stock is the AMOUNT of resourse is present is called stock . eg- petroleum will be exhausted in 50 YRS

This can be determined by evolution of gases as in the CASE of reaction of an acid with a metal where H2 is released.
Evolution of some NEW smell and light is ONE way, as in case of burning.

Helium does not have the highest value of electron affinity among all elements because He being inert do not NEED to add any electron to its valence SHELL DUE to its fully filled valence shell with 2 electrons in it.
Thus Helium does not have the highest value of electron affinity.

To balance a chemical equation you have to equals the MILES of elements on both products and rectans
e.g Mg+O2--->MgO
equal the mole of OXYGEN on the PRODUCT side

Mg+O2--->2MgO
now equal the mole of Mg

2Mg+O2--->2Mgo


now UR equation is balanced . you can balance your equations by using these steps .




I hope you understand it ☺️☺️☺️☺️☺️☺️.


Mark my answer as BRAINLIST ☺️☺️☺️☺️☺️☺️

hydrogen gas is PRODUCED .

put a burning a matchstick from where the gas is evolved ,as hydrogen is EXPLOSIVE it will burn with a pop sound.

thus we test for PRESENCE of hydrogen gas.

We would prefer biopesticide. Biopesticides are living organisms that feeds on PESTS. The organisms used as biopesticides are viruses, bacteria and other INSECTS. There is no side effect on plants, MAMMALS, birds, fish and nontarget insects. Whereas chemical pesticides are toxic. Pathogens and pests develop resistance against them in a short interval. Chemical pesticides kill even useful organisms, harm human BEINGS and animals, pollute soil and water, fruits, vegetables and crop plants.
