tekilochka [14]3 years ago

Answer:

D. s, p

Explanation:

Principle energy levels        number of sublevels               number of electrons

              1                                            1s                                   2n² = 2(1)²= 2

             2                                           2s                                   2n² = 2(2)²= 8  

                                                          2p  

             3                                            3s                                 2n² = 2(3)²=  18    

                                                           3p

                                                           3d

when an atom has 2 energy level it has 1 sublevel (s) in 1st energy level 2 sublevels or orbitals  (s ans p) in second energy.

The total number of electrons accommodate by atoms with n=2 are 10. two electrons in 1s two electrons in 2s and six electrons in 2p.

According to the following reaction, how many moles of carbon dioxide will be formed upon the complete reaction of 28.6 grams of
Musya8 [376]

Explanation:

We have 2CO + O2 => 2CO2.

Moles of CO = 28.6g / (28g/mol) = 1.021mol.

Moles of CO2 = Moles of CO = 1.021mol.
