Read the following passage. Before Rutherford conducted the gold foil experiment, the "plum pudding" model proposed by J. J. Thomson offered an explanation for the structure of the atom. Rutherford, along with two of his associates Hans Geiger and Ernest Marsden, performed an experiment in which an extremely thin metal foil was fired with a beam of alpha particles. The results of the experiment were recorded accurately by another scientist who observed the frequency of alpha particles that passed through the foil unobstructed.

Use information from the passage to justify whether the characteristics of reliable scientific explanations are present in the development of the atomic theory.

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
