Oh yes, it is quite normal to separate the clauses of a sentence with commas.
comma
The comma is optional, but should be used if one or both of the clauses is long.
Yes, when used to join two independent clauses, and as well as the other coördinating conjunctions should be preceded by a comma.
Commas join two clauses where at least one of the clauses is dependent and doesn't make a complete sentence on its own. If both clauses could each make their own sentence if alone, a semicolon is used instead.
A comma should not be used between two independent clauses unless there is a coordinating conjunction connecting them. Commas are also not used before subordinating conjunctions like "because" or "although" when they introduce dependent clauses. Additionally, do not use a comma to separate a subject from its verb within a sentence.
A comma splice is such a comma, when it collects two independent clauses are connected by only a comma. The following example illustrates a comma splice: the job is hard, get some rest.
When you combine two independent clauses, you need to separate them with a semicolon--not a comma. If you use a comma instead of a semicolon, the result is called a comma splice.
A comma is typically needed before a coordinating conjunction joining two independent clauses or to separate items in a list. It is also used after introductory phrases or clauses at the beginning of a sentence.
comma in front of therefore; semi colon in back of therefore
A comma is typically used before "but" when it connects two independent clauses. However, if "but" is joining phrases within a single sentence, a comma is not necessary.
A comma is placed before and (and all other coördinating conjunctions) when the conjunction is being used to combine two independent clauses. In the sentence "My name is Joey, and I am thirteen years old," a comma precedes the conjunction and to hold the two clauses together.
It's comma splice. A semi-colon or full stop should be used instead.
