The NH3 molecule is polar. Explain how does this offer experimental proof that the molecule cannot be planar?
If NH3 were planar, the NH3 bond dipoles would cancel as well as the molecule would be non-polar. If NH3 were planar, the NH3 bond dipoles would amplify as well as the molecule would be polar. If NH3 were not planar, the NH3 bond dipoles would cancel and the molecule would be non-polar. There is no evidence that can confirm the theory that the molecule cannot be planar.

How long does it take to electroplate 0.5 mm of gold on an object with a surface area of 31 cm2 from an Au3+(aq) solution with a 8 A current. Recall the density of gold is 19.3 g/cm3.
Why does LiBr have a stronger lattice energy then LiF Why does NaCl have a higher lattice energy then Mg3N2. ( I thought it would LiF because smaller ion and Mg3N2 because greater charge)
