B is correct
salt lowers the freezing point of water (colligative property) by lowering the interaction and intermolecular forces between water molecules
Answer:
B.) Oxygen is usually -2
Explanation:
Hydrogen is usually +1.
A pure group 1 element is not always +1.
A monoatomic ion can be a range of numbers. However, it must be a charge other than 0.
The Answer is D cause of the people going back and forth.
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
.
