i need the soulation with the explanation

The formal charge on sulfur in SO 4 2- is where the Lewis structure of the ion is: +2 + 4 -4 0 -2 For resonance forms of a molecule or ion, one always corresponds to the observed structure the observed structure is an average of the resonance forms there cannot be more than two resonance structures for a given species the same atoms need not be bonded to each other in all resonance forms all the resonance structures are observed in various proportions Using the table of average bond energies below, the delta H for the reaction is kl. +735 -735 -116 -276 +276 Of the following bonds which is the longest? H - Cl H- Br All are the same H - I H - F According to VSEPR theory, if there are four electron domains in the valence shell of an atom, they will be arranged in a(n) geometry. tetrahedral trigonal planar trigonal bipyramidal octahedral linear

Explanation / Answer

question 23
