Let's work through the questions step by step:

1. **A water molecule contains ___ atoms of hydrogen.**
   - **Answer:** 2 (A water molecule is H₂O, meaning it has two hydrogen atoms.)

2. **The large numbers in front of a formula tell us how many ___.**
   - **Answer:** Molecules (The coefficient in front of a chemical formula indicates the number of molecules.)

3. **A ___ is used to show there are more sets of what’s inside it.**
   - **Answer:** Parenthesis (Parentheses group elements together in chemical formulas.)

4. **A chemical ___ is a shorthand way of representing a compound.**
   - **Answer:** Formula (Chemical formulas represent compounds, e.g., H₂O for water.)

5. **4Al(C₂H₃O₂)₃ contains ___ atoms of Hydrogen.**
   - **Answer:** 12 (Each C₂H₃O₂ group contains 3 hydrogen atoms, and there are 4 × 3 = 12 hydrogen atoms.)

6. **3H₂SO₄ shows that there are ___ molecules.**
   - **Answer:** 3 (The number in front of the formula indicates 3 molecules of sulfuric acid.)

7. **4Al(C₂H₃O₂)₃ contains ___ atoms of Carbon.**
   - **Answer:** 24 (Each C₂H₃O₂ group contains 2 carbon atoms, and there are 4 × 3 = 12 groups, so 12 × 2 = 24 carbon atoms.)

8. **The little numbers behind the symbols are called ___.**
   - **Answer:** Subscripts (Subscripts indicate the number of atoms in a molecule, e.g., H₂ means 2 hydrogen atoms.)

9. **How many times will you multiply elements inside the Parenthesis.**
   - **Answer:** 3 (The subscript outside the parentheses multiplies all elements inside by 3.)

10. **No subscript means there is ___ atom of that element.**
    - **Answer:** 1 (If no subscript is present, it implies only 1 atom of the element.)

11. **A subscript tells how many ___ there are.**
    - **Answer:** Atoms (Subscripts tell the number of atoms in a molecule.)

12. **The large numbers in front of a formula are called ___.**
    - **Answer:** Coefficients (Coefficients tell how many molecules of a compound are involved.)

3. Why is it important to use parentheses in some chemical formulas?
4. How are subscripts used in compounds with polyatomic ions?
5. How can you determine the total number of atoms in a chemical compound?

**Tip:** Always remember that coefficients apply to the entire molecule, while subscripts apply only to the atoms they follow.
