Which of these equations correctly expresses the self-ionization of water?
oh, o+h,0 = h, o+oh
oh, o+h,0 20h-
oh, o+h,0 24,0
oh, o+h,0 - h2o +oh

Explanation:

Self-ionization of water is defined as the reaction where a water molecule deprotonates in order to change into a hydronium ion and hydroxide ion.

For example,

So, here hydroxide ion () is formed along with the formation of hydroxide ion, that is, .

Thus, we can conclude that the equation correctly expresses the self-ionization of water.

1.solid

2.carbon dioxide

3.helium

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
