Question

question 7
food companies can tag their products on the nutrition label as having 0g of trans - fats if they have <0.5g of trans - fat
per serving. what could be found in the ingredients list that is probably a better indicator of the presence of trans - fats
in foods than the trans - fat line on the nutrition label?
olive oil
almonds
hydrogenated oils
lard
palm oil
question 8
which one of the following diagrams represents a trans - fatty acid?

Explanation:

For Question 7: Trans-fats are often formed during the hydrogenation of oils. Even if the nutrition label shows 0g trans-fat (due to <0.5g per serving), hydrogenated oils in the ingredients list indicate the presence of trans-fats. Other options (olive oil, almonds, lard, palm oil) do not inherently signal trans-fats.
For Question 8: A trans-fatty acid has hydrogen atoms on opposite sides of the double bond in the fatty acid chain. Without full diagram clarity, standard trans-fat structures have this "trans" configuration (vs. cis where hydrogens are on the same side). Assuming Option A/B follows this, but common textbook examples link trans-fats to hydrogenated sources (consistent with Q7 logic).

Answer:

Question 7: C. Hydrogenated oils
Question 8: (Note: Diagram clarity is limited, but based on trans-fat structure definition, the option with hydrogens on opposite sides of the double bond is correct. If Option A represents this, then A; if B, then B. For consistency with trans-fat formation, assume the correct diagram is the one with trans configuration.)

(Note: For Question 8, if the diagrams are standard, the trans-fatty acid diagram has hydrogens on opposite sides of the double bond. If Option A shows this, answer A; if B, answer B. Since the prompt’s Q7 links to hydrogenated oils (source of trans-fats), Q8’s correct diagram is the trans configuration.)
