<span>According to octet rule, atoms with an atomic number less than 20 tend to combine with other atom such that both of these atoms have eight electrons in their valence shells, which gives them the same electronic configuration as that of noble gas.
However, there are few compound that donot obey octel rule. Among the elements mentioned above i.e. oxygen and helium obeys octet rule.
In case of nitrogen, oxide of nitrogen (like NO and NO2) have incomplete octet.
While there are few compounds of Br wherein Br has expanded octet. For example, in BrF5, Br has 12 electrons in valence shell. </span>

Explanation:
The two angles would be both 41 degrees.
x in this case would be 14 degrees.
The correct answer to this question is that the length of 14 is it’s half Which would be 7
Agitation, or stirring of the solute in the solvent increases the solubility of the solution
