Accepted Answer

### Question 2 (Classify as Homogeneous or Heterogeneous Mixture)
#### a) Flat soda pop
# Explanation:
## Step1: Recall mixture types. Homogeneous: uniform composition. Heterogeneous: non - uniform.
Flat soda pop (after being flat, still a solution of sugar, flavoring, etc. in water) has uniform composition.
## Step2: Classify. So it's Homogeneous.
# Answer: Homogeneous

#### b) Cherry vanilla ice cream
# Explanation:
## Step1: Analyze composition. Cherry vanilla ice cream has visible chunks of cherry, vanilla - flavored parts, etc. Non - uniform.
## Step2: Classify. So it's Heterogeneous.
# Answer: Heterogeneous

#### c) Salad dressing
# Explanation:
## Step1: Observe salad dressing. It has layers (oil and vinegar - based parts don't mix uniformly, and there are spices etc. in non - uniform distribution).
## Step2: Classify. So it's Heterogeneous.
# Answer: Heterogeneous

#### d) Sugar
# Explanation:
## Step1: Recall substance type. Sugar is a pure substance (compound), not a mixture. But if we consider, but the question is about mixtures. Wait, maybe a typo, but if we assume it's a mixture (but sugar is pure). However, if we consider sugar as a component, but no. Wait, maybe the question is mis - typed, but if we proceed, sugar is a pure substance, not a mixture. But if we consider a sugar - containing mixture, but here it's just sugar. But maybe the question meant sugar solution, but as per the question, sugar (pure) is not a mixture. But maybe the question has an error. But if we assume it's a mixture (maybe a solid mixture, but sugar is pure). So this is a pure substance, not a mixture. But if we have to classify as per the question (maybe a mistake), but if we consider, sugar is a pure substance, so not a mixture. But perhaps the question intended sugar in a mixture, but as given, sugar is pure.

#### e) Soil
# Explanation:
## Step1: Analyze soil. Soil has sand, clay, organic matter, water, air in non - uniform distribution.
## Step2: Classify. So it's Heterogeneous.
# Answer: Heterogeneous

#### f) Aluminum foil
# Explanation:
## Step1: Recall substance type. Aluminum foil is a pure substance (element), not a mixture.
## Step2: So it's not a mixture (pure substance).

#### g) Black coffee
# Explanation:
## Step1: Analyze coffee. Black coffee is a solution of coffee solids in water, uniform composition.
## Step2: Classify. So it's Homogeneous.
# Answer: Homogeneous

#### h) Sugar water
# Explanation:
## Step1: Analyze sugar water. It's a solution of sugar in water, uniform composition.
## Step2: Classify. So it's Homogeneous.
# Answer: Homogeneous

#### i) Air
# Explanation:
## Step1: Analyze air. Air is a mixture of gases (nitrogen, oxygen, etc.) with uniform composition (homogeneous mixture, also called solution of gases).
## Step2: Classify. So it's Homogeneous.
# Answer: Homogeneous

#### j) Paint
# Explanation:
## Step1: Analyze paint. Paint has pigments, solvents, binders in non - uniform distribution (you can see different components if you look closely, and it's not uniform throughout).
## Step2: Classify. So it's Heterogeneous.
# Answer: Heterogeneous

#### k) Iron
# Explanation:
## Step1: Recall substance type. Iron is a pure substance (element), not a mixture.
## Step2: So it's not a mixture.

#### l) Beach sand
# Explanation:
## Step1: Analyze beach sand. Beach sand has different sized particles, shells, organic matter, etc. in non - uniform distribution.
## Step2: Classify. So it's Heterogeneous.
# Answer: Heterogeneous

#### m) Spaghetti sauce
# Explanation:
## Step1: Analyze spaghetti sauce. It has chunks of tomatoes, onions, etc. in a sauce, non - uniform composition.
## Step2: Classify. So it's Heterogeneous.
# Answer: Heterogeneous

### Question 3 (Classify as Physical or Chemical Property)
#### a) Red colour
# Explanation:
## Step1: Recall property types. Physical property: observed without changing substance's chemical identity. Color is a physical property.
## Step2: Classify. So it's Physical.
# Answer: Physical

#### b) Density
# Explanation:
## Step1: Recall property types. Density is a physical property (measured without changing chemical identity).
## Step2: Classify. So it's Physical.
# Answer: Physical

#### c) Flammability
# Explanation:
## Step1: Recall property types. Flammability is a chemical property (relates to ability to undergo combustion, a chemical change).
## Step2: Classify. So it's Chemical.
# Answer: Chemical

#### d) Solubility
# Explanation:
## Step1: Recall property types. Solubility is a physical property (dissolving is a physical process, no new substance formed).
## Step2: Classify. So it's Physical.
# Answer: Physical

#### e) Reacts with acid
# Explanation:
## Step1: Recall property types. Reacting with acid is a chemical property (involves a chemical reaction, new substance formed).
## Step2: Classify. So it's Chemical.
# Answer: Chemical

#### f) Bitter taste
# Explanation:
## Step1: Recall property types. Taste is a physical property (observed without chemical change).
## Step2: Classify. So it's Physical.
# Answer: Physical

#### g) Melting point
# Explanation:
## Step1: Recall property types. Melting point is a physical property (related to phase change, physical process).
## Step2: Classify. So it's Physical.
# Answer: Physical

#### h) Reacts with water
# Explanation:
## Step1: Recall property types. Reacting with water is a chemical property (involves chemical reaction, new substance formed).
## Step2: Classify. So it's Chemical.
# Answer: Chemical

#### i) Hardness
# Explanation:
## Step1: Recall property types. Hardness is a physical property (measured without chemical change).
## Step2: Classify. So it's Physical.
# Answer: Physical

#### j) Odor
# Explanation:
## Step1: Recall property types. Odor is a physical property (observed without chemical change).
## Step2: Classify. So it's Physical.
# Answer: Physical

#### k) Smooth texture
# Explanation:
## Step1: Recall property types. Texture is a physical property (observed without chemical change).
## Step2: Classify. So it's Physical.
# Answer: Physical
