How many bonds can each atom make without hybridization s3s23p4?

The s3s23p4 will only make up to one bond for any sub orbital that is partially filled.

There are 3 bonds each atom can make without hybridization if it’s going to fill a (s,p,d,f). 2s22p3 takes 3 more to fill it to 2p6. That makes it 3 bonds.

Equation is as follow,

                                 H₂SO₄ + NH₃   →   HSO₄⁻ + NH₄⁺

H₂SO₄ goes to HSO₄⁻:

a) H₂SO₄ has lost one proton.

b) It is a Brønsted -Lowery acid as it has donated H⁺.

NH₃ goes to NH₄⁺:

a) NH₃ has gained proton.

b) It is a Brønsted -Lowery base as it has accepted proton.
