CIO4-=-1

CI=4O=-1

CI+(-8)=-1

CI=-1+8=7

So the oxidation number of chlorine is 7 in this case

How does the force of gravity on Jupiter compare to the force of gravity on Earth?
iogann1982 [59]

Jupiter has greater gravitational pull than earth, about 2.4 time greater than that of earth. This means that a person weighing 100 pound on earth will weigh 240 pounds on Jupiter.

Jupiter is the largest planet in the solar system. It is so large that all other planets would comfortably fit inside it. It is over 1000 times bigger than the earth.

Jupiter is the fifth planet from the sun and rotates faster than any other  planet. A day in Jupiter is about 10 hours long.

Vlad1618 [11]

A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element.

<em>For example, the empirical formula of ethanol may be written C2H6O because the molecules of ethanol all contain two carbon atoms, six hydrogen atoms, and one oxygen atom.</em>
