Sodium chloride is made up of sodium and chlorine.
sodium chlorine would form an ionic bond, which is the transfer of electrons
because sodium is in group 1, it has 1 electron on its outermost shell
because chlorine is in group 7, it has 7 electrons on the outermost shell.
sodium and chlorine both want a full outer shell. therefore, sodium and chlorine will form an ionic bond, and sodium will transfer its one electron to chlorine so that it can lose its electron and get a full outer shell, and chlorine can gain an electron and also get a full outer shell. this can be represented using the dot and cross model. as shown in the picture.
but don't forget to add a 1- charge to chlorine with brackets and a 1+ charge to sodium, also with brackets.
hope this helped.. I know it became really long but I didn't really realise it once I was half way.. anyway, if you have any questions just ask :)
Answer:
Explanation:
7 carbon atoms, 6 hydrogen atoms,9 NO2 atoms
7+6+9=22
2(22)=44
44 atoms
The final molarity of HCl is 2.284 M
We'll begin by listing what was given from the question. This is shown below:
Initial volume (V₁) = 5.56 mL
Initial Molarity (M₁) = 4.108 M
Final volume (V₂) = 5.56 + 4.44 = 10 mL
<h3>Final Molarity (M₂) =? </h3>
The final molarity of the HCl solution can be obtained by using the dilution formula as illustrated below:
<h3>M₁V₁ = M₂V₂</h3>
4.108 × 5.56 = M₂ × 10
22.84048 = M₂ × 10
Divide both side by 10
M₂ = 22.84048 / 10
<h3>M₂ = 2.284 M</h3>
Therefore, final molarity of the HCl solution is 2.284 M.
