Electric bill problem 3.0 (20 points) what is the total cost of using the following at /kwh? a. 1600 w air conditioner for 6h b. 1200 w hair dryer for 15 min .4800 w clothes dryer for 30 min d. 900 w coffee maker for 10 min 200 w play station 3 for 2 h e. f. 50 w stereo for 3.5 h

The total const is 13025 KWh

Explanation:

These are the steps to solve this problem:

Convert all the powers from W to KW dividing by 1000.Convert all the times on minutes to hours dividing by 60.Then you can apply energy consumption formula for any of the appliances. the results will be at KWh.Sum all the consumtions and you will have the total cost.

Attached you will have a spreadsheet as a guidance. Any  questions, just let me know.

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
