Accuracy is more of a range
Hey there!
Oxygen needs two bonds to have a valence orbital of s²p⁶.
In a hexanal molecule, oxygen has a double bond with one carbon atom.
A double bond is when two pairs of electrons are being shared.
So your answer is b. 2.
Hope this helps!
Answer: The molarity of the borax solution is 0.107 M
Explanation:
The neutralization reaction is:

According to neutralization law:

where,
= basicity of
= 2
= acidity of borax = 2
= concentration of
= 1.03 M
= concentration of borax =?
= volume of
= 2.07ml
= volume of borax = 20.0 ml
Now put all the given values in the above law, we get the molarity of borax:

By solving the terms, we get :

Thus the molarity of the borax solution is 0.107 M
Hopefully this helps sorry
I really dont know. please add more details for answers. i will be back as soon as you post details!
