26. the amount of water. the amount of water is constant in the planet and when evaporation takes place. rain come and balance the amount of water evaporated.
27. dynamic means that the process takes place. as the equilibrium tries to balance, a reaction should take place.
28. by using a double arrow
29. this arrow shows only one direction of reaction. but for equilibrium reactions, it should be a double arrow to show the reaction is reversible.
30. A homogeneous equilibrium
has everything present in the same phase. The usual examples include
reactions where everything is a gas, or everything is present in the
same solution while heterogeneous equilibrium
has things present in more than one phase. The usual examples include
reactions involving solids and gases, or solids and liquids.
....please best me in this answer.
