Final answer:
The recipe ingredients are mostly mixtures, including the egg, vanilla extract, baking powder, flour, walnuts, and apples. Sugar is the only pure substance. The properties of these ingredients can be categorized into intensive physical (e.g., color), extensive physical (e.g., mass), and chemical (e.g., reactivity).
Step-by-step explanation:
The ingredients of the recipe can be classified as pure substances or mixtures. A pure substance has uniform and definite composition, while a mixtures is composed of different substances that retain their own individual properties.
- An egg is a mixture because it contains different substances like proteins, fats, and water.
- Sugar is a pure substance (sucrose).
- Vanilla extract is a mixture containing various compounds.
- Baking powder is a mixture of a carbonate or bicarbonate and a weak acid.
- All-purpose flour is a mixture of proteins, starch, and other compounds.
- Chopped walnuts are a mixture of various compounds.
- Diced apples are a mixture of fibers, sugars, and water.
Regarding their properties, we can categorize them into intensive physical, extensive physical, and chemical properties:
- Intensive physical properties don't depend on the amount of matter. Examples: boiling point, density, and color.
- Extensive physical properties do depend on the amount of matter. Examples: mass, volume.
- Chemical properties refer to a substance's ability to undergo a specific chemical change. Examples: flammability, reactivity.
