Oh yes, it is quite normal to separate the clauses of a sentence with commas.
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.
Yes, a comma can separate two independent clauses when they are joined by a coordinating conjunction (for, and, nor, but, or, yet, so). For example: "I wanted to go for a walk, but it started to rain." Without a conjunction, a semicolon is typically used instead of a comma to separate the clauses.
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.
When combining two independent clauses, a comma must be placed before the coordinating conjunction (for, and, nor, but, or, yet, so). For example, in the sentence "I wanted to go for a walk, but it started to rain," the comma precedes "but." If the clauses are not joined by a conjunction, a semicolon can be used instead.
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.
