Draw the correct lewis structure for nh3.

I think this Is the correct answer

Explanation:

nitrogen is an element of atomic number 7 and so has 5 electrons in its valence shells. it requires 3 more electrons to complete its octet.nitrogen shares an electron with 3 atoms of hydrogen each to achieve this. hydrogen being an element with atomic number 1 requires 1 more electron to reach the electronic configuration of its nearest noble gas, helium. so it shares an electron with nitrogen

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
