Determine if each solution is acidic, basic, or neutral.

[H3O+] = 1 x 10-10 M; [OH-] = 1 x 10-4 M

[H3O+] = 1 x 10-7 M; [OH-] = 1 x 10-7 M

[H3O+] = 1 x 10-1 M; [OH-] = 1 x 10-13 M

[H3O+] = 1 x 10-13 M; [OH-] = 1 x 10-1 M

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
