2 Counting Atoms and Elements in a Chemical
A model of (CH20), was created using colored beads, Carbon atoms were
represented by black beads, hydrogen atoms by red beads, and oxygen atoms
by blue beads. Which of the following combinations of beads shows an accurate
model of (CH2O)4?
A 4 black, 8 red, and 4 blue
B
1 black, 2 red, and 1 blue
C 4 black, 6 red, and 4 blue
D
1 black, 8 red, and 1 blue

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.

actually the answer is c
