C- K4O8 and K2O4
K4O8/4 =KO2
K2O4/2 =KO2
Answer:

Explanation:
S is in 3d period, so it has 3 levels
1 level has 2 electrons, 2d level 8 electrons, 3d level 6 electrons

The reactants that will form products will be
.
<h3>Activity series</h3>
Elements at higher positions in the activity series will be able to displace those in lower positions in solutions.
Thus:
because Br is higher than I in the activity series.
Cl cannot displace F in
because F is higher than Cl in the activity series.
Also, Cl is higher than Br in the activity series, thus, the reaction
cannot form products.
I cannot displace F, thus,
cannot form products.
