superoxide.
(a)H3PO4
(b)Al(OH)3
(c)SeO2
(d)KNO2
(e)In2S3
(f)P4O6
(a)H3PO4
(b)Al(OH)3
(c)SeO2
(d)KNO2
(e)In2S3
(f)P4O6
1 answer:
Answer:
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.

The maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × P a. So, the correct option is (b).
Radiation pressure is the name for the force electromagnetic wave particles exert on a surface. It is inversely related to the wave's speed. Given data
Solar constant ( S ) = 1350W / m ^2
Now, the radiaton pressure is given by
P = 2 S /c
where c is the speed of the light
P = 2 × 1350 /3 × 10 ^8
P = 9 × P a
For a black surface, P = 4.5× P a
Therefore, maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × P a
