Answer:
Hurricanes occur when ocean water warms during the spring, summer and early fall.
Explanation:
Warm air just above the water’s surface rises. The rising warm air creates a reduction in pressure at the surface, what meteorologists call a low-pressure area. Because nearby air is at a higher pressure, it will flow into the low-pressure zone.

A battery converts a chemical reaction into an electrical energy.
Answer:
There must be two Chlorine atoms for every one Calcium atom in order to fulfill Chlorine's octet rule and pair Calcium's unpaired electrons.
Explanation:
Calcium has two unpaired electrons in its Lewis dot structure, while Chlorine has one unpaired electron.
<em>So why can't we just make a double bond for </em><em>one</em><em> Chlorine?</em>
Chlorine has seven valence electrons, so once it shares electrons with Calcium, the octet rule is accomplished, and no more pairs can be made.
Answer: 334.6 moles of O, 167.3 moles as O2
Explanation:
20.15x10^25/6.02214076x10^23 = 334.6 as atoms, 167.3 as O2
