The correct option is;
A. 0
Explanation:
The ammonia molecule has four pairs of electron whereby being located around the central nitrogen atom is tetrahedral in shape.
Of the four pairs of electrons, three are the bonds between nitrogen and hydrogen, such that there is only one lone pair of electron in the ammonia molecule that is located on the central nitrogen atom
The one electron on each hydrogen atoms and one of the electrons on the nitrogen atom form a bonding pair of electrons, that is the bonding pair of electrons are shared by the two nuclei, hydrogen and nitrogen
Since a lone pair are a pair of electrons attached to only one nucleus, the hydrogen in ammonia has no lone pair of electrons.
Answer:
2.00 moles of Ni has 1.2 *10^24 atoms
Explanation:
Step 1: Data given
Number of moles Ni = 2.00 moles
Number of Avogadro = 6.022*10^23 /mol
Step 2: Calculate number of atoms
Number of particles (=atoms) = Number of Avogadro * number of moles
Number of atoms = 6.022 * 10^23 /mol * 2.00 moles
Number of atoms = 1.2*10^24 atoms
2.00 moles of Ni has 1.2 *10^24 atoms
Answer:
The answer to your question is below
Explanation:
Element Atomic number Protons Electrons
S (sulphur) 16 16 16
V (vanadium) 23 23 23
B (Boron) 5 5 5
The molecular polarity of the sun is the dipoole separation of electric charge leading to a molecule in the sun.
<h3>What is molecular polarity?</h3>
Molecular polarity simply refers to those regions of molecules containing or possessing positive and negative charge
So therefore, the molecular polarity of the sun is the separation of electric charge leading to a molecule in the sun.
