Describe how to use le chatelier’s principle to predict the possible ways a chemical system can respond to changes.

The equilibrium law is used to predict the change in the conditions of the chemical equations in equilibrium. The changes in temperature, pressure, and volume can change the chemical reaction conditions.

The equilibrium law can predict the change as:

Thus, the change in the condition can alter the dynamic equilibria, then the direction of reaction will be countereffect to attain equilibrium.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
