The Balance of Reaction

THE BALANCE OF REACTION

The reaction of chemistry there are those that took place one direction (ireversibel) and there are those that took place two directions (reversibel). The reaction reversibel (that is the reaction took place in two directions) meaning that at the same time the reagent substance was formed again.
The equality of the reaction reversibel was written: A2 + B2 -->  2AB
At the time of certain the reaction reversibel could achieve The balance situation, the balance of chemistry was dynamic.
The implement and the material

The name of the implement and the material The measurement or the unit The number
The tube of the reaction While
The tube shelf of the reaction
The glasses pipe
The glasses pipe
The liquid was coloured (tea water) Adequate
The procedure:
1. The contents of one of the tubes of the reaction with the coloured liquid hinga half of it, let the tube one empty.
2. Put the glasses pipe in respectively the tube of the reaction that (empty and contained the liquid. )
3. By using the glasses pipe moved the coloured liquid to the empty tube, after the empty tube contained by using the glasses pipe to this tube moved the liquid to the tube originally. Be careful did not have the liquid that spilled (saw the picture)


The question
After several times the liquid was moved by you in accordance with the procedure
1. How the number of liquids in respectively the tube?
2. If the analogy it was considered a reaction, the B tube (empty) as results of the reaction, at the time of at first is there results of the reaction?
3. When being reached the balance, how the number mole the reagent and results of the reaction?
4. How the rate of the reaction to the right compared with the rate of the reaction to left?
