After listening for weeks to her boyfriend Steve bragging about his mother's chili, Amy
anticipated the first delicious spoonful, the hair floating among the beef and beans,
however, killed her appetite.

In this sentence several grammatical errors are observed:

1.chili, Amy. It is not a merged sentence

2.spoonful, the. There is an error, since the comma between two sentences creates a splice error

Explanation:

1.The explanation is that a comma is missing in the main sentence (After listening for weeks to her boyfriend, Steve bragging...), since when a sentence is in the participle it has a main sentence, therefore, you must separate both sentences with a comma.

2.The text reads that "Amy anticipated that the first delicious spoonful" is the first sentence. The hair that floated among the beef and the beans, however, killed her appetite" is the second sentence. That comma should not be because it would create a splice error between the two sentences. To solve it you can use the word "but" before "the" and eliminating “however”.

the irony is that the name has ''fortunate'' in it, but the kid named fortunato is not fortunate to be named that.
