Predicting the hybridization pattern of the central atom and the geometrical configuration from CO2 CCl4 ; SO3, C03; C ( Z = 6 ) , CI ( Z = 17 ) , S ( Z = 16 ) ; O ( Z = 8 ) - The central atoms of the molecules CH4, NH3, and H2O are sp hybridized. Compare bond angles HCH , HNH , HOH and explain why

Which is not true regarding reaction rates? (2 points) catalysts are not used up in the reaction. catalysts speed up reactions by lowering the activation energy. reaction rates decrease as the concentration of reactants decrease. during reactions, concentrations of all reactants decrease at the same rate.
