Determine the oxidation states of the elements in the compounds listed. none of the oxygen-containing compounds are peroxides or superoxide.
(a)h3po4
(b)al(oh)3
(c)seo2
(d)kno2
(e)in2s3
(f)p4o6

Explanation:

You need to remember that the oxidation number of H is +1, except when it is in a metal hydrites like NaH, where its oxidation number is -1. Then, the oxidation number of O is -2, but in peroxides is -1. So with these rules you just have to multiply the ox. number with the name of atoms and all the elements in the reaction must sum 0.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
