Answer: (1 Kilogram = 2.20462 pounds) . There are 2.2046226218 lb in 1 kilogram. To convert kilograms to pounds, multiply your figure by 2.205 for an approximate result. 1 kilogram is also equal to 2 lb and 3.27396195 oz. Working out a rough estimate in your head for converting to pounds and ounces may be tricky - remember that there are 16 ounces in a pound.
Answer: C) Tetrahedral
Explanation:
The number of electron pairs is 4 that means the hybridization will be
but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.
Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be
.
Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be
.
Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be
.
Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be
.

or simply 2,8 it is isoelectronic with argon
Q1. They are highly reactive. Q2. High reactivity, nonmetallic. Q3. Oxygen has an ion charge of -2. Q4. LiCl I believe. Q5. How electrons are shared. Q6 1. Q7. Share 2 valence electrons, I believe.
