What evidence do scientists use to explain how the solar system formed? a) all the planets were a result of solar flares from the sun. b) all the planets are made of the same material, mainly helium. c) all the planets orbit in an elliptical pattern in the same direction. d) all the planets were a result of meteorites that were pulled together by gravity

The research is published in the most recent issue of leading scientific journal Nature Communications. About 4.6 billion years ago, a cloud of gas and dust that eventually formed our solar system was disturbed. The ensuing gravitational collapse formed the proto-Sun with a surrounding disc where the planets were born.

the ratio of the conjugate base to the acid required to attain the desired ph.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
