What are the spectator ions in 2h+ + so42- + ca2+ + 2r → caso4 + 2h+ + 21?

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
