Below are the choices:
A.) an unpaired electron,
<span>B.) a nonbonding electron pair, </span>
<span>C.) a bonding electron pair, </span>
<span>D.) a high value of electronegativity
</span>
The correct answer is B.) a nonbonding electron pair,
The volume that is needed to react completely with 0.100 mol of lead nitrate is 0.400 L. It is because 2 moles of HCl are required for every mole of lead nitrate.
2 x 0.100 mole Pb(NO₃) = 0.200 mole HCl
0.200 mol HCl = L x 0.500 M
Silicate. It is silica, SiO2 with contaminants such as Fe3+ that give it color. technically it is a tecto-silicate.<span>

Atomic no = no of electrons present in atom
and atomic mass = no of protons + no of neutrons
