A simple epithelium has cells that form a single layer that are attached to the basement membrane. A stratified epithelium, on the other hand, consists of multiple layers of cells where only the basal layers are attached to the basement membrane.
Explanation:
A substance that completely dissociates into ions when dissolved in its aqueous solution is known as a strong electrolyte.
Whereas a substance that does not dissociate into ions is known as a non-electrolyte.
If a substance partially dissociates into ions when dissolved in its aqueous solution then it is known as a weak electrolyte.
(a)
As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.
(b)
As partial dissociation of ions take place in this reaction as the reaction is in equilibrium state. Hence, it is a weak electrolyte.
(c)
Here, complete dissociation of ions is taking place as the reaction is not in an equilibrium state. Therefore, it is a strong electrolyte.
(d)
Here also complete dissociation is taking place. Hence, it is a strong electrolyte.
(e)
As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.
Answer:
In first shell duplet rule is applied because first shell contains maximum 2 electrons
Explanation:
Answer:
Increasing the temperature
Explanation:
According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
Since the forward reaction is exothermic, this suggests that heat is given off in the reaction.
Increasing the temperature will favors the reverse process which is endothermic.
In going from the reactants to the the products, the reaction is deemed exothermic which suggests that it produces heat.
The backward reaction is endothermic i.e it absorbs heat. If the temperature is increased, this process will be favored and more reactants produced. Less of the diiodine pentoxide will form. There is a leftward shift of the equilibrium
