Question

1.How many number of covalent bonds are there in 0.5 mole of NH3?
2.By which method we can find covalent bonds? ​

Answer 1

Answer:

1.)

have never heard of bonds quantified in moles… One molecule of  NH3  ccontains 3 covalent bonds, so one mol will contain 3 moles of bonds. And half a mol will contain 1.5 moles of bonds.

2.)

The types of covalent bonds can be distinguished by looking at the Lewis dot structure of the molecule. For each molecule, there are different names for pairs of electrons, depending if it is shared or not. A pair of electrons that is shared between two atoms is called a bond pair

Answer 2

Answer:

1.The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.
