Accepted Answer

### Question 2
# Brief Explanations:
A chemical equation is a written representation of a chemical reaction using symbols and formulas. So the clue "A written way to show a chemical reaction, with symbols and formulas" matches option G (Chemical Equation).
# Answer:
G. Chemical Equation

### Question 3
# Brief Explanations:
A balanced equation has an equal number of atoms of each element on both sides of the equation. So the clue "Describes an equation where the number of atoms is equal on both sides" matches option E (Balanced).
# Answer:
E. Balanced

### Question 4
# Brief Explanations:
A coefficient is a large number written in front of a chemical formula to show the number of molecules. So the clue "A large number written in front of a chemical formula showing how many molecules are present" matches option C (Coefficient).
# Answer:
C. Coefficient

### Question 5
# Brief Explanations:
A closed system is a setup where no matter can leave or enter during a reaction. So the clue "A setup where no matter can leave or enter during a reaction" matches option K (Closed System).
# Answer:
K. Closed System

### Question 6
# Brief Explanations:
Products are the new substances formed during a chemical change. So the clue "The new substances that are formed during a chemical change" matches option L (Product).
# Answer:
L. Product

### Question 7
# Brief Explanations:
A chemical reaction is a process where reactants change into products. So the clue "A process where reactants change into products" matches option F (Chemical Reaction).
# Answer:
F. Chemical Reaction

### Question 8
# Brief Explanations:
The Law of Conservation of Mass states that matter cannot be created or destroyed in a reaction. So the clue "States that matter cannot be created or destroyed in a reaction" matches option A (Law of Conservation of Mass).
# Answer:
A. Law of Conservation of Mass

### Question 9
# Brief Explanations:
In a chemical reaction, atoms are rearranged into new arrangements. So the clue "What happens to atoms in a chemical reaction - they are put into new arrangements" matches option B (Rearranged).
# Answer:
B. Rearranged

### Question 10
# Brief Explanations:
A subscript is a small number written to the lower right of an element symbol showing the number of atoms in a molecule. So the clue "A small number written to the lower right of an element symbol showing the number of atoms in a molecule" matches option D (Subscript).
# Answer:
D. Subscript

### Question 11
# Brief Explanations:
A precipitate is a solid that forms from a reaction between two liquids. So the clue "A solid that forms from a reaction between two liquids" matches option H (Precipitate).
# Answer:
