Answer:
calcium is a metal and metals are good conductors of electricity as they contain mobile electrons.
Explanation:
B, I would believe. There are 58, but B is the closest we can get.
Answer:
When two single single bonds separated by a double bond (e.g C=C-C=C or C=C-C=O in the case of 2-cyclohexenone), the effect of resonance among those there bonds will be observed.
Explanation:
Since the Oxygen atom has higher electronegativity, it will cause the electrons in the resonance bonds 'flow' toward the Oxygen atom, so that the C=C will 'lose' some electron. The signal read for that bond will be different from other alkene structure.
Attachment is the resonance structure of 2-cyclohexene.
Psolution = X · PH_20
= 0.966 · 31.8 torr
= 30.7 torr
Add an alkaline compound to raise the pH to 7.2.
