2. The number of possible alkynes with molecular formula C5H8 is …………….
3. (a) Name two ores of Zn and Cu both.
(b) What is the value of orbital angular momentum for a ‘d’ electron?
4. What is salt hydrolysis?
5. What is Le Chatelier’ s principle?
6. The energy of an particle is 6.8 × 10 – 18
J. What will be the wavelength associated with it?
7. A 10 litre flask contains 0.2 mole of methane, 0.3 mole of hydrogen and 0.4 mole of nitrogen at 25oC.
What is the partial pressure of each component and what is the pressure inside the flask?
8. 1 litre mixture of CO and CO2 is taken. This is passed through a tube containing red hot charcoal. The
