Heavy water is used in CERTAIN TYPES of NUCLEAR REACTIONS where it act as Newton's moderators to Slow Down neutrons so that they are more likely to this

CAN YOU SAY IT IN ENGLISH PLEASE

THE VALENCY OF ELEMENT 8 IS 2 AND 9 IS 1

A FUEL produce NATURALLY from the REMAINS of plants and ANIMALS BURIED in soil and rocks know as fossil fuels

This method is used to prepare soluble salts. E.G. the addition of granulated zinc to a dilute solution of tetraoxosulphate (VI) acid - effervescence of hydrogen OCCURS.

Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)

The solution is filtered, leaving insoluble impurities, such as excess zinc and particles of carbon on the FILTER paper. The ZnSO4 is then crystallized from the solution.

If it is INSOLUBLE than first we HEAT it to MAKE a suitable METHOD

Na PLUS CL is base and ACID which make it a suitable one

⭐Actually welcome to the CONCEPT of the ELECTRON WITHDRAWING GROUPS ...

⭐Basically here we can see that. ..

⭐-NO2 , IS a type of electron withdrawing group ..THUS it's more presence will have more -R effect in the compound .. resulting more ACIDIC hydrogen ....

⭐Thus the order should be ...

⭐HC (NO2)3 > H2C (NO2)2 > H3CNO2

THE ANSWER ARE D AND B

The chlorine ATTACHED to the benzene contain excess of electrons which is +R effecting GROUP. Due to RESONANCE the electron DENSITY increases at ortho and para position. HENCE it is ortho para directing group.

Zn shows an OXIDATION state of +2. Thephenol GETS converted into phenoxide ion and PROTON thus RELEASED accepts an electron from Zn forming H radical. ... In this way zinc forms zinc oxide and phenyl radical thus produced forms a bond with H radical. HOWEVER, the yield of this reaction used for benzene formation is lower

Making and BREAKING bonds. To start a reaction, ENERGY must be ABSORBED by the CHEMICALS in order to break some of the chemical bonds in the reactants. The amount of energy needed to start a reaction in this way is called the activation energy.

The ability of a cation to DISTORT an ANION is KNOWN as its polarizationpower and the tendency of the anion to become polarized by the cation is known as its polarizability.
Chemical bonds are BROADLY classed as covalent and ionic. ... These cations are said to be polarising ( or have high polarising power) because they distort the electron cloud of the anion, and the electron density between the nuclei is higher than in the CORRESPONDING ionic bond.

hope this will help u... :-)

Cobalt is PLACED before Nickel EVEN through their atomic MASSES are not in increasing ORDER...

Hey mate here is your answer》》

Ca(OH)2 --> Ca^2+ + 2OH- From 1 MOL of Ca( OH)2, 1 mol of Ca^2+ ions and 2 mol OH- ions are PRODUCED, for a total of 3 mol ions.

Hope this answer will help you..《《

Economic equilibrium is a CONDITION or state in which economic forces are balanced. ... Economic equilibrium may also be defined as the point at which supply EQUALS demand for a product, with the equilibrium PRICE existing where the hypothetical supply and demand CURVES intersect.

No. Of MOLES present in the GIVEN sample
=given mass/atomic mass
Atomic mass of H2O is 18g
Moles present =45/18
=2.5 moles.
No. Of H2O molecules present =AVOGADRO NUMBER*number of moles present
=6.023*10^23*2.5
=15.0575*10^2 Molecules

1 GRAM atom = N – atoms = 6.023 x 1023atoms = gram atomic weight

gram atomic weight = weight of  N atoms in grams

1 gram MOLECULE = N- molecules = 6.023 x 1023 molecules = gram molecular wt.

gram molecular wt. = wt. of N molecules in gram

number of MOLES of molecules ‘n’ = wt. (gram)/ molecular wt.= w/ m

number of moles of atoms ‘n’ = wt. (gram)/ atomic wt.

no. of moles ‘n’ = no. of PARTICLES / ( 6.023 x 1023)

I HOPE it will HELP you

⭐Actually welcome to the concept of the ELECTROCHEMISTRY

⭐Basically APPLYING the GIBBS ENERGY equation for the Equilibrium condition of the EMF of the cell we get as

⭐E° = 0.0591/n . log (k~eq)

⭐since here the CHANGE in e~ is 1 and the E° = 0.591

⭐we get the answer as

⭐K~eq = 1 × 10^10

Down the GROUP it DECREASES and ALONG a PERIOD it INCREASES

Hi...

Let me tell you the answer first....

1 )   aqueous sodium hydroxide + X   ----->  green PRECIPITATE

                    X =  iron ( ii ) compound

  EXPLANATION :

                    Let us take FeSO4 as iron ( ii ) compound

                    If i react FeSO4 and NaSO4, it will be a double decomposition reaction...

                    The two compounds dissociate to form,

      FeSO4 (aq)   ----------->    FE2+ + SO4 2-

      2NaOH (aq)  ---------->     2Na+ + 2OH-

                 Then, Fe 2+ will react with 2OH- and 2Na+ will react with SO4 2- to give Fe(OH)2 and Na2SO4

                     Hence the reaction goes like,

      FeSO4 (aq) + 2 NaOH (aq)  ---------->  Fe(OH)2 ( green precipitate ) + Na2SO4

--------------------------------------------------------------------------------------------------------------

2 )   Aqueous sodium hydroxide + Y --------->  light blue precipitate

                Y = copper ( ii ) compound

Explanation :

                 Let me take copper sulphate as copper ( ii ) compound

                 If i react NaOH and CUSO4, its a double decomposition reaction.

  CuSO4( aq)+ 2NaOH(aq)   ----------->  Cu(OH)2 ( light blue precipitate )+ Na2SO4

( the procedure is as same as the previous reaction )

hence,

X = iron ( ii )

Y = copper ( ii )

          THANK U !!!! HOPE IT HELPS YOU.....
