Answer:
A fan is a common house appliance which is attached to the ceiling and uses an electric motor to rotate blades or paddles in a circular motion. Ceiling fans help cool a room by moving air which causes evaporative cooling. Fans range in size from 36 inches to 56 inches using 55 to 100 watts, a typical 48 inch ceiling fan will use 75 watts.
where you have
Hours Used Per Day:5
Power Use (Watts): 75
Price (kWh): 0.01
then you have
Cost Per Hour=0.0075
Cost Per Day= 0.0375
Cost Per Month=1.14
Cost Per Year=13.69
kWh Per Day: 0.38
Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.

The IUPAC naming of compounds follow a set of rules. First, find the longest carbon chain and number them. As shown in the picture, the longest chain has 9 carbons. In the 3rd and 5th carbon atoms, there is a double bond for each. So, the parent chain is named as 3,5 - nonadiene, 'di' because there are two double bonds. Moreover, at the 5th carbon, there is a branching chain of two carbons (ethyl). Hence, its IUPAC name is: <span>(3e,5z)-5-ethyl-3,5-nonadiene.</span>
