c) Hydroxides
d) They don't react
Answers
Answer:
Explanation:
idation state of -1; and the superoxide ion, O2-, has a oxidation state of -1/2. With metals, oxygen forms oxides that are largely ionic in character.
There are general trends in the reactions between main group elements and oxygen:
Most nonmetals form the oxide with the highest possible oxidation state, with the halides excepted. Most metals form oxides with the oxygen in a -2 oxidation state.
As a general rule, metal oxides are basic and nonmetal oxides are acidic. Basicity of an oxide increases with increasing ionic (metallic) character. Metal oxides, peroxides, and superoxides dissolve in water actually react with water to form basic solutions. Oxygen also forms covalent oxides with non-metals, that react with water to form acidic solutions.
Oxygen does not react with fluorine or noble gases.
Exceptions to all of these trends are discussed below.
Reactions with Hydrogen
Oxygen reacts with hydrogen to produce two compounds: water ( H2O ) and hydrogen peroxide ( H2O2 ). Water is a versatile compound and participates in acid-base equilibrium and oxidation-reduction reactions. It can act as an acid, base, reducing agent, or oxidizing agent. Water's multifaceted abilities make it one of the most important compounds on earth. The reaction between hydrogen and oxygen to form water is given below:
2H2(g)+O2(g)→2H2O(l)(1)
Hydrogen peroxide's potent oxidizing abilities give it great industrial potential. The following equation shows the reaction of hydrogen and oxygen to form hydrogen peroxide:
H2+O2→H2O2(2)
The product of this reaction is called a peroxide because oxygen is in the O2−2 form (hydrogen has a +1 oxidation state). This concept is further explained regarding lithium below.
