Answer:

3 (s,p,d)

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 3 energy level it has 1 sublevel (s) in 1st energy level 2 sublevels (s ans p) in second energy and three sublevels in third energy level (s,p,d). This atom with n=3 can accommodate 18 electrons in these sublevels.

Answer:

The answer to your question is    HCl  +  NaOH   ⇒   NaCl  +  H₂O

Explanation:

Data

Double displacement reaction

Balanced chemical reaction

               HCl  +  NaOH   ⇒   NaCl  +  H₂O

           Reactants           Elements                Products

                 1                  Chlorine (Cl)                    1

                 1                   Sodium (Na)                   1

                 2                 Hydrogen (H)                  2

                 1                   Oxygen (0)                      1

As we can see, the reaction is balanced and the coefficients of all reactants and products are 1, but the number is not written in a balanced reaction.
