A substance that accelerates any chemical reaction but is not consumed in the reaction is a _____.catalyst
buffer
substrate

Answers

The right answer is the catalyst.

In chemistry, a catalyst is a substance that increases the rate of a chemical reaction; it participates in the reaction but it is neither part of the products nor reagents and therefore does not appear in the equation-balance of this reaction.

The catalyst accelerates, sometimes in considerable proportions, the chemical reaction, but it is not consumed: either it does not participate in the reaction but its presence facilitates the breakage of the bonds, or it participates but is regenerated at the end.

Catalysts are widely used in industry and laboratory.

In nature and in biochemistry, some proteins have catalytic activity. They are enzymes.

your ans is a. catalyst

Explanation:

Sometimes new information results in minor changes to a theory. But sometimes new information results in a theory being discarded as incorrect. An example of an incorrect theory that was disproved by the discovery of new information isPtolemy’s theory of the solar system.
the original cell theory.
the germ theory.
plate tectonic theory.

Answers

An example of an incorrect theory that was disproved by the discovery of new information is Ptolemy’s theory of the solar system. The correct option among all the options that are given in the question is the first option. Ptolemy’s theory stated that the earth is the center of the universe. I hope it helped you.

The Ptolemy's theory of the solar system was disproved by the discovery of the new information. The Ptolemy's theory stated that the Earth is at the center of the solar system and all the planets, suns and stars orbited around it while the Earth stayed completely stationary. However, this theory was proven to be false as the sun-centeric model of the solar system better explained various phenomenon, such as the particular movement of the planets.

Hence, the correct answer is 'Ptolemy's theory of the solar system'.
