Web developers use html tags in angle brackets to format the text on web pages (see appendix c). write a method removetag that checks whether a given string starts with an apparent html tag (a character or word in angle brackets) and ends with a matching closing html tag (the same character or word preceded by the „\‟ character, all in angle brackets). if yes, the method removes both tags and returns the result; otherwise the method returns the original string unchanged. for example, removehtmltags("strings are immutable") should return a string equal to "strings are immutable".

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.

Just trying to get some points : p sorry bro
