Question

Match the appropriate food item with the indicator chemical you would use to detect the principal organic molecule present in that item.

Note: some indicator chemicals may be used for more than one of these food items or not at all.

Group of answer choices
maple syrup

benedict's solution
lard (animal fat)

sudan IV
Cheerios cereal

iodine
chicken breast

benedict's solution

Answer 1

Here are the appropriate food items matched with the indicator chemicals used to detect the principal organic molecule present in each item:

1. **Maple syrup** - **Benedict's solution** (to detect sugars, particularly reducing sugars like glucose)

2. **Lard (animal fat)** - **Sudan IV** (to detect lipids or fats)

3. **Cheerios cereal** - **Iodine** (to detect starch)

4. **Chicken breast** - **Benedict's solution** (though usually proteins are more commonly detected using other methods; however, it can also contain some sugars)

To summarize:
- Maple syrup → Benedict's solution
- Lard → Sudan IV
- Cheerios cereal → Iodine
- Chicken breast → Benedict's solution (with some caution regarding the assay's relevance)
