Answer:
Increased evaporationof water vapour from sea or land will increase rainfall
Answer: D) 1 lone pair, square pyramidal
Explanation:
Formula used : ![\text{Number of electrons}=\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
where,
V = number of valence electrons present in central atom = 7
N = number of monovalent atoms bonded to central atom = 5
C = charge of cation = 0
A = charge of anion = 0
Now we have to determine the hybridization of the 
molecule.
![\text{Number of electrons}=\frac{1}{2}\times [7+5+0-0]=6](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5B7%2B5%2B0-0%5D%3D6)
Bond pair electrons = 5
Lone pair electrons = 6-5 = 1
The number of electrons are 6 that means the hybridization will be 
and the electronic geometry of the molecule will be octahedral .
But as there are five atoms around the central iodine atom, the sixth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be square pyramidal.
70.5g x 1 mol / 58.5g = 1.2mol of nacl

Explanation:</h3>
SI units relate to the International System of Units. These units are the base, metric units that are most commonly accepted for different measurements.
Common SI Units
The most common SI units are as follows:
- Length - meter (m)
- Time - second (s)
- Mass - kilogram (kg)
- Amount of substance - mole (mole)
- Electric current - ampere (A)
- Temperature - kelvin (K)
- Volume - liter (L)
*Note that gram (g) is not an SI unit
Each type of measurement will only have 1 SI unit. This is the unit that will be expected for most answers. Sometimes this means converting an answer into a different unit so it is more widely accepted.
Why SI Units are Important
SI units are important for the same reason that the metric system is used. It gives a standardized list of measurements that scientists across the world can use. Also, it makes it easier to compare scientific findings and studies when all of the measurements are given in the same units.
There are times when it is unrealistic to use SI units. For example, when discussing space, using meters will not be realistic due to the size of space. Also, when measuring the mass of small elements, kilograms are too large. But otherwise, SI units should be used.
