Question

Accepted Answer

### Question 1
# Brief Explanations:
An element is a pure substance that cannot be broken down into simpler substances by physical or chemical means. A compound can be broken down chemically, and a mixture can be separated physically. So the correct answer is A.
# Answer:
A. An element Color BLACK

### Question 2
# Brief Explanations:
Water ($H_2O$) is a compound, gold is an element, and Kool - Aid is a mixture (it has multiple substances dissolved in water). So the correct answer is C.
# Answer:
C. Kool - Aid Color GREEN

### Question 3
# Brief Explanations:
A solution is a homogeneous mixture where substances are evenly distributed and appear as a single substance. A suspension has particles that settle, and a colloid has particles that scatter light but are not as evenly distributed as a solution. So the correct answer is A.
# Answer:
A. A solution Color LIGHT GREEN

### Question 4
# Brief Explanations:
Salad is a heterogeneous mixture (you can see the different components), while honey and soy sauce are homogeneous mixtures (the components are evenly distributed). So the correct answer is A.
# Answer:
A. Salad Color YELLOW

### Question 5
# Brief Explanations:
A compound is a substance made of 2 or more elements that are chemically combined in a set ratio. The first option is a mixture, the second is an atom. So the correct answer is C.
# Answer:
C. A substance made of 2 or more elements that are chemically combined in a set ratio Color RED

### Question 6
# Brief Explanations:
Copper is an element, dirt is a mixture, and carbon dioxide ($CO_2$) is a compound (made of carbon and oxygen elements chemically combined). So the correct answer is B.
# Answer:
B. Carbon dioxide ($CO_2$) Color LIGHT BLUE

### Question 7
# Brief Explanations:
An element and a compound are pure substances and cannot be broken down by physical means. A mixture can be separated by physical means (like filtration, evaporation etc.). So the correct answer is C.
# Answer:
C. A mixture Color GREEN

### Question 8
# Brief Explanations:
In a solution, the solute is the substance being dissolved, and the solvent is the substance doing the dissolving. A molecule is a general term for a group of atoms. So the correct answer is C.
# Answer:
C. Solute Color PURPLE

### Question 9
# Brief Explanations:
Hydrogen is an element (it is a pure substance made of only hydrogen atoms). Pizza is a mixture, and methane ($CH_4$) is a compound. So the correct answer is A.
# Answer:
A. Hydrogen Color BROWN

### Question 10
# Brief Explanations:
Elements and compounds are pure substances. A mixture is made of 2 or more substances and is not a pure substance. So the correct answer is C.
# Answer:
C. A mixture Color BLUE

### Question 11
# Brief Explanations:
Iron filings are magnetic, and sand is not. So magnetic attraction can be used to separate iron filings from sand. Filtration is for separating solids from liquids, and evaporation is for separating a solute from a solvent. So the correct answer is B.
# Answer:
B. Magnetic attraction Color GRAY

### Question 12
# Brief Explanations:
Mayonnaise is a colloid (it has small particles that do not settle and scatter light). Muddy water is a suspension (particles settle), and tea is a solution. So the correct answer is B.
# Answer:
B. Mayonnaise Color WHITE

### Question 13
# Brief Explanations:
Italian salad dressing is a suspension (the components can separate over time). Whipped cream is a colloid, and gelatin is a colloid. So the correct answer is A.
# Answer:
A. Italian salad dressing Color DARK GREEN
