There are six electrons in the covalent bonds.
Two N atoms would be :N:· + ·:N:
An N₂ molecule would be :N:::N: or :N≡N:
This gives each N atom an octet of eight electrons in its valence shell.
Hello! yes, very much.

<u>Answer:</u> Copper (I) iodide will precipitate first.
<u>Explanation:</u>
We are given:
of CuCl =
of CuI =
Concentration of
Concentration of
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.
Putting values in above equation, we get:
Concentration of copper (I) ion =
Putting values in above equation, we get:
Concentration of copper (I) ion =
For the precipitation of copper (I) ions, we need less concentration of copper (I) ions. So, copper (I) iodide will precipitate first.
The correct option is: PERFORM BACKGROUND RESEARCH TO LEARN WHAT IS ALREADY KNOWN ABOUT THE QUESTION YOU ARE TRYING TO ANSWER.
No research is completely new, some research has been done in the past that is related to the investigation you want to carry out, so the first thing you should do is to find out what has been done in the past in your topic of interest and how you can fit in with your research, this is called literature review. Conducting a literature review is very important, because it helps you to avoid doing what other has done in the past.
