I don't know what you mean by type of 18, but it is called inorganic chemistry.
Answer: 1 × 10−2 M
Explanation: Kw is known as the constant of water dissociation and its value is found to be
. It is the product of the concentration of [H3O+] and [OH -] ions .
Dissociation of water can be represented by -

Kw = [H3O+] [OH -]
As we know that pKw = - log Kw,
Thus pKw = 14
pOH = - log OH- = - log (10^{-12}) = 12
and pKw = pH + pOH
14 = pH + 12
pH = 14 - 12 = 2
pH = -log H3O+
2 = -log H3O+
Therefore, [H3O+] = 1 × 10−2 M
Answer:
C
Explanation:
it only bonded with one other molecule carbon/ oxgen=carbon dioxide
The products and reactants weigh the same since u have to balance out the equation to have an equal number of molecules on bothsides
2 to 4. Im pretty sure you might have to check me on it but as far as i know 2 to 4 years.
