What is Henery'sLaw?

What is Henery'sLaw?


Answer: According to this law solubility of a gas is directly proportional to the partial pressure of the gas.Solubility of a gas is represented by its mole fraction in the solution.
Mathematically  P = Kh  X 
where P = partial pressure of gas
Kh = Henery's constant
X = mole fraction of gas
As it is clear from above relationship
X is inversly proportional to Kh
And Kh is found to be decreased by increasing temperature so solubility decreases by increasing temperature.That is why aquatic life is more comfortable in cold water than in hot water.

Can PCl3 act as an oxidising as well as reducing agent?

Can PCl 3   act as an oxidising as well as reducing agent? If yes, how? Illustrate with the help of equations. ANswer: Yes, PCl 3   can act both as an oxidising agent as well as reducing agent. It react with sulphur tri oxide to reduce it to sulphur di oxide. PCl 3   +SO 3   -------------> POCl 3   + SO 2 It also react with metals like silver and sodium to form their chlorides. PCl 3   + 6 Na ---------------> 3 NaCl +Na 3 P

A compound lens is made of two lenses in contact having powers +12.5 D and -2.5 D. An object is placed at 15 cm from this compound lens.Find the position and nature of the image formed.

Question: A compound lens is made of two lenses in contact having powers +12.5 D and -2.5 D. An  object is placed at 15 cm from this compound lens.Find the position and nature of the image formed. Answer: P comp  = P 1   +P 2   = + 10 D F comp   = 100/10 cm 1/F =1/v - 1/u F = +10 cm, u = -15 cm, v = ?                                                                V= +30 cm  Image formed will be real inverted and enlarged.

Show that all the bonds in PCl5 molecule are not equivalent.

 Show that all the bonds in PCl 5   molecule are not equivalent. Answer: Since Phosphorus penta chloride  breaks down into phosphorus trichloride and chlorine gas on heating which shows that out of five P-Cl bonds three are equitorial and tightly  bonded and two are axial and weak  bonds.
