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.

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

u i forgot the answer?

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
