Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below.
what experimental evidence led to the development of this atomic model from the one before it?
a few of the positive particles aimed at a gold foil seemed to bounce back.
the colors of light emitted from heated atoms had very specific energies.
experiments with water vapor showed that elements combine in specific proportions.
cathode rays were bent in the same way whenever a magnet was brought near them.

How much energy moves onto the next level, in an energy pyramid

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
