Which factors ALL increase reaction rate? decrease temperature, stir, increase surface area, remove catalyst

none of these

increase temperature, increase surface area, add catalyst, stir

increase temperature, stir, decrease surface area, add catalyst

increase temperature, increase surface areas, add catalyst, stir

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

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

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
