Answer:
Tetrahedral
Bent
Explanation:
A molecule in sp3 hybridization is ordinarily expected to exhibit tetrahedral electron domain geometry. This implies that it has four electron domains.
We were specifically informed in the question that two lone pairs are present. Remember that lone pairs distort the molecular geometry away from the expected geometry based on VSEPR theory.
Therefore, the bond angle of the molecule is <<109.5 degrees and its molecular geometry is bent (e.g water)
PV = nRT
Pressure times volume = number of moles times ideal gas constant times temperature
50mL = .05L
1 atm (.05) = n (.0821) (273)
.05 = n (22.4133)
.022 = n (number of moles)
6.022E23 molecules = 1 mole
.022 x 6.022E23 = 1.325E23 molecules
Answer:
1.They break the bonds between the ions.
2.They remove electrons from the ions.
Explanation:
covalent bonds do not dissolve in water but some covalent compoound s do
