Decomposition of kclo3 is sometimes used to prepare small amounts of o2 in the laboratory: 2kclo3>>>2kcl+3o2. How many grams of o2 can be prepared from 4.50g of kclo3

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

no but i do not usually comment or use my voice that much when it comes to social media
