Question

i don't know how to write chemical formulas is it like nomenclature because i need to balance equations (which i know how if the equation is given to me the symbols type but not in words), i need to write skeletal equations but i don't know if they are correct.


example: 2H2+O2->2H2O (i get this )
Potassium chlorate -> potassium chloride +oxygen (i need help with questions like these because i don't know what to write for the numbers for each one but i know my oxyacids)
KClO3->KCl+O2 (i don't know if this is right or not

Answer 1

Yes, KClO3 is potassium chlorate.
The best thing I can tell you to memorize the polyatomic ions. For example,
ClO3^- is chlorate
SO4^2- is sulfate
NO3^- is nitrate etc.
Here is a table. Time and usage will makes this easier.
