Seperate independent clauses when they are joined by verbs.
The main rule of a comma is to use it to separate the elements in a series of three or more things. You should also use a comma to set off quoted elements and to separate coordinate adjectives.
The sentence, "She was born in Kansas in 1782," does not require any comma. The meaning of the sentence is perfectly clear without one. I'm not aware of any rule that automatically requires a comma following a place name. There is, I believe, a rule requiring a comma if the sentence had referred to "Wichita, Kansas." (Of course, one would have to overlook the fact that there was no Wichita, Kansas in 1782.) In the sentence within parenteses, some people place a second comma after Kansas (e.g. ... no Wichita, Kansas, in 1782).
The general rule is that it doesn't need a comma before it. Example: I like apples as well as guavas.
Comma UseIf you are linking two complete clauses (complete clause meaning containing both a subject and verb), you would use a comma before the conjunction to avoid violating the run-on sentence rule. If the clauses in your sentence share one subject, the comma is not necessary. Examples"I am going to the store, and I will pick up Sam on the way.I am going to the store and will pick up Sam on the way.The comma is omitted in the second example because the second clause does not have its own subject and cannot stand alone.
In series or lists like "bread, butter and jam" vs "bread, butter, and jam" there is no strict rule. It largely depends on geography (with the US being most adherent of adding the extra comma) and also depends on medium (newspapers and magazines very rarely use extra commas before the last and/or). In general just think about it and if the series is ambiguous then add an extra comma, if not then you're free to leave it out, although if you want to add the extra comma as a personal preference then you're free to add it and still technically be correct.
Every style manual I have referenced indicates that the proper use is to include the comma so that it looks like this: i.e.,
No. There is no rule that a comma must always follow the word "which." In a parenthetical or appositive phrase, however, a comma may be required.Example:I did what I thought was right which, as I came to find out, was not.
Sometimes, but not always. There is no one single rule that applies to "but." ----
grammatical commas are something that is used with phrases

In most cases, the word "sit" does not need to be capitalized after a comma unless it is the start of a new sentence. The general rule is to capitalize the first word of a new sentence, regardless of whether it follows a comma.
