Answer:
<u>True</u>, some molecules have the same molecular formula as their empirical formula.
Explanation:
The empirical formula of many compounds may be the same. Formaldehyde, for example, has the chemical formula CH2O, which is equal to the empirical formula of glucose. Each molecule of formaldehyde has one carbon atom, two hydrogen atoms, and one oxygen atom.

Answer:
Sp3 hybridization
Explanation:
The NH3 molecule, which consists of one lone pairs and three bond pair of electron on its valance shell due to lone pair bond pair repulsion makes bond angle of 107.5°resulting distorted tetrahedral geometry.
Hybridization =no. of bond pair +lone pair=3+1=4=sp3 hybridization
