Write down the chemical reactions taking place in the extraction of zinc from zinc blende.

In table-3 write the names of the organisms in the appropriate box according to where i they can be found. You could put the name of one organism in more than one column. If you put the organism in the colon in 'some other place', try to mention the place where you could find it.Some examples are filled in to help you. Copy the table 3 in your notebook. Try to enhance the list as much as you can. How many organisms are present in more than one column? Why did you place them here?

Write the procedure involved in the acid and leaf experiment to understand the concept "how the stomach gets protected from its own acid secretions ". Compare the observations with the changes that takes place in human digestive system.

According to molecular orbital theory, atomic orbitals of nearly same energy of different atoms are combined and form molecule. In homodiatomic molecule two atomic orbitals which have wave function psi_(A) and psi_(B) are combined in two ways (psi_(A)pm psi_(B)) . They have two type of electron density, one is bonding [(psi_(A) pm psi_(B))^(2)] where e- density increase between nucleus. Another is antibonding [(psi_(A)pm psi_(B))^(2)] where e^(-) density decreases between nucleus. These molecular orbitals are filled according to Hund, Pauli, afbau principle. Existence of molecule depends on bond order. where bond order = ("Number of bonding "e^(-)"s- number of antibonding "e^(-)s)/(2) lf the molecule have unpaired electron it is paramagnetic otherwise diamagnetic Statement- 1: Removal of two e^(-) from N^(2) , magnetic behaviour does not change while addition of two electrons in O_(2) magnetic behaviour changes. Statement-2: In N_(2) removal of electron talces place from bonding orbital while addition of e^(-) in O_(2) is in antibonding orbital
