2.Help plsss Why are fossils so important? What type of information about the environment and
organism do they provide. (think about finding a fish fossil in the desert)

i dint kniw if its true but i think beacues it helps scientist determaine what was befpre us

Explanation:

its temperature is increasing. this causes molecular vibrations to increase.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
