Make a decision about the molecule nahco3 classification organic or inorganic

is an inorganic compound.

Solution:

Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.  Secondly, Sodium is a metal which organic compounds cannot posses as a compound.  Lastly, there is absence of C-H bond which is present in all the organic compounds.

Hence, we can conclude that is an inorganic compound though there is presence of Carbon atom in it.

Iguess i would say diagrams would be most difficult subject too correct

Answer:

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

explanation:

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.
