Answer : The correct option is, (c) pyramidal
Explanation :
As we are given that a molecule in which the central atom forms three single bonds and has one lone pair that means the central metal atom has 3 bond pairs and 1 lone pair of electrons.
There are total 4 electron pairs. So, the hybridization will be 
and the electronic geometry of the molecule will be tetrahedral.
But as there are three atoms or bonds around the central atom and the fourth position occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be pyramidal.
Hence, correct option is, (c) pyramidal
It is highly reactive and when it is kept in open it does react with the oxygen present in the surroundings and burns therefore it is kept immersed in kerosene and please thank me and if you need more comment
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
The force exerted on the Kite is 49.6 N.
<u>Explanation:</u>
Force is nothing but the product of pressure exerted by the wind on the kite and the area of the kite.
F = P × A
Where,
F is the Force in Newton = ?
P is the Pressure = 113 Pa = 113 N/m²
A is the Area of the Kite
A = 0.836 m × 0.525 m = 0.4389 m²
Now, we can find the force as,
F = 113 N/m² × 0.4389 m²
= 49.6 N [ ∵ In the units, m² gets cancelled]
So the force exerted on the Kite is 49.6 N.
Which physical
property can be measured? color density odor shape
The physical property that can be measured is the
density. Color, odor and shape are properties that cannot be measured. They can
be only observed through the naked eye and is subject to qualitative measurement.
