3) (4.5 x 10-14) x (5.2 x 103) = ?

16603.6

or

1.66036 x 10^4

Hope this helps! ^_^

16,603.6

Explanation:

(4.5 x 10 - 14) x (5.2 x 103)

(45 -14) x 535.6

31 x 535.6

16,603.6

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
