Answer:
Using valence bond theory, HgCl2 is sp hybridized while PCl3 is sp3 hybridized.
Explanation:
sp hybridized molecules are largely covalent and cannot conduct electricity hence the nonconducting nature of HgCl2. PCl3 contains a lone pair and three unpaired electrons in sp3 hybridized orbitals.
The pairs are:
K, Kr - Same period
Be, Mg - Same group
Ni, Tc - Both are transition metals
B, Ge - Both are metaloids
Al, Pb - Both form inert oxides
Answer:
c
Explanation:
the oxygen in the air and water from the rain caused oxidation causing the copper wire to become tarnished.
Option one ( which is Aluminium Carbonate ) is the answer
Calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature, pH, and dissolved ion concentrations. Although calcite is fairly insoluble in cold water, acidity can cause dissolution of calcite and release of carbon dioxide gas.
