Answer:
Substances used to make the bomb
The area it was placed
Which people were in that area
How the bomb was set off
Explanation:
Examining the residues left at the scene by the bomb could tell forensics what the bomb was made out of, and the police could investigate possible leads about people who purchased (or have access to) such materials.
The area should give clues because security cameras could be used to trace who was there that should not be. There would be a possible suspect.
If it is a public place, then we can see if there is anyone of importance (to the suspect) that was there at that time.
If a remote detonator was used to set off the bomb, then the suspect would have to be relatively close to the bomb.

Answer: The complete nuclear symbol will be 
Explanation:
The nuclear symbol is written as: 
where Z= atomic number , A = mass number X = symbol of element
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
For an electrically neutral atom,
Atomic number = Number of electrons = Number of protons = 8
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Mass number = 8 + 10 = 18
Thus complete symbol will be
A Brønsted-Lowry acid is defined as a compound that gives hydronium ions to another compound—for example, hydrochloric acid gives H+ ions to compounds it reacts with. Brønsted-Lowry bases are compounds that can accept hydronium ions—when ammonia gets a hydronium ion from HCl, it forms the ammonium ion.
