Sure! Let's check your answers.
For substances or mixtures:
1. Carbon Dioxide - Your answer: M (Mixture)
- Explanation: Carbon dioxide is a pure substance, so the correct answer here would be S (Substance).
2. Salt water - Your answer: M (Mixture)
- Explanation: Salt water is indeed a mixture, so your answer is correct.
3. Table salt - Your answer: M (Mixture)
- Explanation: Table salt, also known as sodium chloride, is a pure substance, not a mixture. Therefore, the correct answer would be S (Substance).
For homogeneous or heterogeneous matter:
1. Flat soda pop - Your answer: Heterogeneous
- Explanation: Flat soda pop is typically a homogeneous mixture due to its uniform composition.
2. Aluminum foil - Your answer: Homogeneous
- Explanation: Aluminum foil is a pure substance and can be considered homogenous, so your answer is correct.
3. Black coffee - Your answer: Homogeneous
- Explanation: Black coffee is typically a homogeneous mixture due to its uniform composition.
4. Beach sand - Your answer: Heterogeneous
- Explanation: Beach sand is a heterogeneous mixture, consisting of various particles of different sizes and compositions. So, your answer is correct.
5. Pure air - Your answer: Homogeneous
- Explanation: Pure air is considered a homogeneous mixture because it consists of a mixture of gases that are uniformly distributed.
6. Spaghetti sauce - Your answer: Homogeneous
- Explanation: Spaghetti sauce can vary, but generally, it is a heterogeneous mixture due to the presence of various ingredients like tomatoes, herbs, and spices.
Overall, you did a good job! Just remember to differentiate between substances and mixtures, as well as homogeneous and heterogeneous matter.
