Ion is an atom or molecule with a net electric charge due to loss or gain of one or more electrons.
Answer:
12
Explanation:
There are 4 sulfur atoms in SO4
4×3=12
This means that it turns into 3×(SO4)
=3SO4
The fifth shell can hold up to 50 electrons and the forth shell can hold 8 electrons
Answer: Option (B) is the correct answer.
Explanation:
A molecules that will have more number of hydrogen bonding will has highest boiling point because to break the hydrogen bonds high heat needs to be provided.
So, in the molecule 
there is presence of two alcoholic groups. Hence, it will have strongest hydrogen bonding as compared to the rest of molecules.
In the molecule 
there will be hydrogen bonding and dipole-dipole interactions. Hence, it boiling point will be slightly less than .
In the molecule 
, there will be only hydrogen bonding. Hence, its boiling point is less than .
In the molecule 
, there is no hydrogen bonding but there will be only dipole-dipole interactions. Hence, its boiling point will be the least.
Therefore, we can conclude that increasing order of boiling point will be as follows.

Answer:
DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease
