A covalent bond means shared electrons between atoms. This is similar to kids sharing markers because the markers (electrons) are being shared between the kids (atoms). Covalent bonds are different than this metaphor because 1) the electrons are constantly moving about while the kids can steal and keep the markers and 2) the electrons and atoms are physically smaller
Explanation:
Let us assume that the concentration of [
and
is equal to x. Then expression for
for the given reaction is as follows.
![K_{w} = [OH^{-}][H^{+}]](https://tex.z-dn.net/?f=K_%7Bw%7D%20%3D%20%5BOH%5E%7B-%7D%5D%5BH%5E%7B%2B%7D%5D)


Now, we will take square root on both the sides as follows.
M
Thus, we can conclude that the
concentration in neutral water at this temperature is
M.
Answer:
The correct answer is "11.44 ml".
Explanation:
Molarity,
= 0.2 M
Density,
= 1.05 g/ml
Volume,
= 1 L
As we know,

That’s because when a charged chemical species composes of two or more atoms (covalently bonded), they act as a single unit. the term radicals refers to free radicals that are with an unpaired electron and because not all of its electrons are found in pairs
