Answer:
phone, microwave, internet box
1 - 8
2 - 13
3 - 20
4 - 19
5 - 19
6 - 22
* protons - Atomic number
electrons - number of electrons is equal to number of protons k-41 is neutral
neutrons - Mass number - Atomic number
= 41 -19
= 22
The two resonating structures of Carbon Monoxide are shown below.
The movement of electrons are shown by arrow.
Structure A: In structure a A the formal charges of Carbon and Oxygen are zero. As
Formal Charge is calculated as,
= # of valence electron - electrons in lone pairs + 1/2 bonding electrons electrons
For C: = 4 - 2 + 4/2
= 4- 4
=
0For O: = 6 - 4 + 4/2
= 6- 6
=
0Structure B:
Formal Charge on C: = 4 - 2 + 6/2
= 4- 5
=
-1Formal Charge on O: = 6 - 2 + 6/2
= 6 - 5
=
+1
Answer: correct answer is D
It can be traced example in copper rod or iron or any other pure metal
The kind of reaction that is likely to be observed is a single displacement reaction where the metal displaces the H+ ion from the acid. The general chemical reaction would be written as 2M + 2HX = 2MX + H2 where M represents a metal and HX is the acid.
