Determine the empirical formula for dioxin C12H4C14O2

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

it is stable as it is in group 0 which have full outer shells of electrons

yes the answer is total mass in unchanged   : )
