Double Replacement Reactions
By Jill Larson
In this interactive object, learners identify charges on ions, write new formulas based on charge, and balance equations using coefficients.
Learners examine how five or six groups of electrons around a central atom cause the shape of the molecule to be trigonal bipyramidal, seesaw, T-shaped, linear, octahedral, square pyramidal, or square planar. Seven examples and three interactive questions are provided in this animated activity.
