sorry i couldnt find another diagram but this one shows lithium(left) and chlorine(right)
instead of this, draw an oxygen atom and two lithium atoms
one electron from each lithium atom will go to the oxygen atom, making it an octat
and don't forget to draw those charges on top.
since lithium loses electrons, it becomes positive and since oxygen gains electrons, it becomes negative
um you got it?

Can someone help in Question Number 9, Summer 2009 in Chemistry paper 3.
And also why Temperature supports the backward reaction like in the graph Q6 (b)
Click to expand...
As you see for question no 6 .....
They have sed that the forward reaction is exothermic ....... Which mns less temp is needed fr the formation of Ammonia ......
And so just imagine wat happens when the temp increases..... The vice versa takes place ...which is ..whn the temp is high ...... Less yield of NH3 is formed :D hope u gt it .....
