I believe the power was separated so that no one group of people had to much power. It is the basic gest of why we separate a lot of things so that everyone has equality and all power is not going to one person or group who does things in favor of another person or group.

Answer: congress is the branch that collects taxes, and executive makes a state of the union address each year

And for your second question the answer is executive because as the branch address that The President “shall from time to time give to the Congress Information of the State of the Union, and recommend to their Consideration such measures as he shall judge necessary and expedient.
