Determine the oxidation numbers of each of the elements in the following reaction, and identify which of them are oxidized or reduced, if any: SiO_2 (s) + 2 H_2 O(l) rightarrow H_4 SiO_4 (aq) (a) SiO_2 i Si O (b) H_2 O: H O (c) H_4 SiO_4 H Si O Which are oxidized? Si O H None Which are reduced? Si O H None Enter the oxidation number as a "+" or "-"followed by the numeral. For example. +6. The "-"character can be found under "special characters" in the "Tools" tab in the answer module (see image below).
