If you hang a bird feeder, fill it with food but no birds come to it what would the hypothesis be?

You could have many hypothesis...

Explanation:

A hypothesis is a guess as to what is going to happen in a situation. Without knowing the exact question you are developing a hypothesis for I can't give you an exact answer and the hypothesis takes place before the experiment. So you wouldn't know why the birds didn't come.

But if I had to give a bs answer I would say that the conditions weren't ideal for the birds (ie not right location or type of food)

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
