Looking up a word in a dictionary can be a complicated process. for example, assume you want to look up "logic." you might open the dictionary to a random page and see "juice." you know this word comes alphabetically before "logic," so you flip forward and see "lamb." that is still not far enough, so you flip forward and see "monkey." you have gone too far, so you flip back, and so on. draw a structured flowchart or write pseudocode that describes the process of looking up a word in a dictionary. pick a word at random and have a fellow student attempt to carry out your instructions.

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.
