922.202

Explanation:

4.192+ 913.30+ 4.71 complying with sig figs would be solved like this:

004.192+ 913.300+ 004.710= 922.202

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

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

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
