Rohit I do not know any poem. BUt the best way to remember inorganic is to do it daily in short time. Give 15 mins twice a day for 3-4 months and you will be able to retain most of it.

This is 10 mole CO which has 10 mole oxygen atom or 5 mole oxygen molecules.

If we move down the group the number of proton added is equal to number of electron added so an outer most electron should see same charge at the center. But this does not happen as inner electron of d and f block cannot do not provide same repulsion due to poor screening. Due to this effective central charge increases for outer electrons. This leads to phenomenon like lanthanide contraction.

Right reduction and oxidation equations as two separate equations. Now multiply them with suitable numbers and add to remove all the electrons. That will give you balanced equation.

Heat of hydrogenation is equal to heat of formation of hydrogenated compound - heat of formation of unhydrogenated compound. For example heat of hydrogenation of ethene is heat of formation of ethane- heat of formation of ethene.
Catalogs Discussion Forums -> Mechanics -> An open bamboo pipe has a fundamental frequency "f".The tube is dipped veritcally into wat -> Go to message

Shashank you have not completed the question. For an open pipe fundamental frequency is v/2L.Once the pipe is dipped in water it will behave like a closed pipe and its fundamental frequency will be v/4l where l is new length of tube.If l =L/2 then fundamental frequency will remain same in both the cases.

Catalogs Discussion Forums -> Physical Chemistry -> henry's law constant for co2 in water is 1.67*10*8 Pa at 298K calculate the quntity of co2 -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

Quantity of CO2 in water will depend on partial pressure of CO2. If partial pressure is PCO2 then mole fraction(xCO2) of CO2 in water is given by 

x CO2= PCO2/H=PCO2/(1.67*10^8)

They are attracted by strong nuclear force which is stronger than electrical force at small distance of 10^(-15) m.

Let partial pressure of COCl2 CO and Cl2 be x,y,y.x+2y = 2y^2/x = Kpy^2/Kp+2y-2=0Solve this quadratic to get ydegree of dissociation = y/(x+y)=y/(2-y)
Catalogs Discussion Forums -> Inorganic Chemistry -> why sulphurtrioxide acts as reducing agent only? -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
It does not acts as a reducing agent. For it to work as a reducing agent it has to get oxidised. And sulphur already has +6 oxidation state in SO3 so it can't get oxidised.
Catalogs Discussion Forums -> Physical Chemistry -> why ice is less denser than water????? -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
Because due to hydrogen bonding water molecules make a more open crystal structure which increases volume of water or decreases density. And yes there is no air in the crystal as posted by Nitin

No effect as nuclear reactions do not participate in chemical reaction.

It is velocity of ion or charge carrier on application of unit electic field.

This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

 I am assuming that the gas is at STP.  22.4 ltr of gas has a mass of 22.4*1.7 = 38g = 1mole of gas. If the mixture has x mole of CO and (1-x) mole of CO2 then 28x+44*(1-x) =38. Solve to get x and hence composition of mixture.

Sorry Bhawna but can't give Walsh diagram for AX4 in this post. And it is beyond the scope of IITJEE so don't worry about that.

As a text book take O P Aggarwal or TMH chemistry. For physical chemistry you can solve problems from R C Mukharjee. You can use J D Lee for Inorganic and Boyd for Organic as reference books.
