Answer:
2. idiom
3. hyperbole
4. metaphor
5. onomatopoeia
6. simile
7. idiom
Explanation:
I'm not 100% confident in these answers tbh BUT
2. "heart skipped a beat" is not something that literally happens when you're frightened, an idiom has hidden meaning besides what the text actually says
3. "I don't know how much longer I can go without eating." hyperbole because the sentence is dramatic and not actually insinuating that the speaker is starving or famined
4. "apple of my eye" is a very common metaphor comparing the beauty of an apple to the eye with the beauty of a person to the eye
5. "CLANG of pots and pans" these are usually visual sounds such as POW or BOOM in writing styles
6. "as white as snow" similes compare two subjects using words such as "like" and "as" in between the two subjects
7. "heart is stone" is pretty much the same as "heart skippped a beat"
