In regards to bond angles affected by electron electron repulsion, we don't need to know the exact angles of those angles. Just know that repulsion reduces bond angles.

The De Broglie equation works for any particle that has a mass when the momentum is 0. Since photons never have 0 momentum, you can't use this equation for such particles.

The equation is used to determine the uncertainty in position and momentum since we can't determine the exact position of an electron like we can normal everyday objects like a baseball.

Balancing equations deals simply with making sure that the number of atoms are equal one both sides of the equation. This is based on the law of conservation of mass, which means that atoms can neither be created or destroyed.
