Final answer:
The sentence provided is a run-on because it contains two complete sentences without proper punctuation or conjunctions. It can be corrected using various punctuation marks or by adding coordinating or subordinating conjunctions.
Step-by-step explanation:
The sentence “I love pizza tomorrow we will eat it” is indeed a run-on sentence because it consists of two complete sentences that have been combined without proper punctuation or a coordinating conjunction. To correct the run-on, one could separate the two sentences with a period, a semicolon, or connect them using a comma followed by a coordinating conjunction such as “and”, as in “I love pizza, and tomorrow we will eat it.”
Alternatively, one could also use a subordinating conjunction to join the sentences so that one becomes dependent on the other, such as “I love pizza; therefore, we will eat it tomorrow.”
