The coordinating conjunctions that can be used to combine two complete sentences with a comma are “for, and, nor, because, yet, so”?

You're very close! The coordinating conjunctions that can be used to combine two complete sentences with a comma are called the FANBOYS:

* For

* And

* Nor

* But

* Or

* Yet

* So

The conjunction because is a subordinating conjunction which doesn't work the same way. It's used to introduce a dependent clause that explains the reason for the main clause.

Example:

* Correct: I went to the store, and I bought some milk.

* Incorrect: I went to the store, because I bought some milk. (This structure makes it sound like the reason for going to the store was to buy milk, which isn't logically correct.)

Remember to always use a comma before the coordinating conjunction when joining two independent clauses.
