What is the source of potential energy for the circuit shown in the picture above?

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

What is the mass of 0.46 mil of mgcl2

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.
