What is the molecular formula of ferrous nitrate and ferric nitrate

Ferric iron has a charge of 3+, while ferrous iron has a charge of 2+. The nitrate anion looks like this:

NO3-

so the balanced compounds would be:

Ferric Nitrate: Fe(NO3)3
Ferrous Nitrate: Fe(NO3)2

Hope this helps!

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.
