In science, the Law of Conservation of Matter tells us that matter cannot be created or destroyed, only Response area. This means that during both chemical changes and physical changes, the total amount of Response area stays the same, even though its Response area might change. For example, when you burn a piece of paper (a Response area change), it may seem like the paper disappears, but its atoms are actually transformed into ash and gases. Similarly, when you melt an ice cube (a Response area change), the water molecules remain the same; they just change from a solid to a liquid state. Whether matter undergoes a dramatic chemical change or a simple physical change, the total number of Response area involved doesn't increase or decrease. This fundamental principle helps scientists understand and explain many processes in our world, from cooking in the kitchen to complex industrial reactions.

Answer 1

To complete your request, I'll fill in the blanks, match vocabulary definitions, and answer the questions based on the typical terms used in chemistry. Here's the completed information:

Complete the paragraph:

In science, the Law of Conservation of Matter tells us that matter cannot be created or destroyed, only transformed. This means that during both chemical changes and physical changes, the total amount of matter stays the same, even though its form might change. For example, when you burn a piece of paper (a chemical change), it may seem like the paper disappears, but its atoms are actually transformed into ash and gases. Similarly, when you melt an ice cube (a physical change), the water molecules remain the same; they just change from a solid to a liquid state. Whether matter undergoes a dramatic chemical change or a simple physical change, the total number of atoms involved doesn't increase or decrease. This fundamental principle helps scientists understand and explain many processes in our world, from cooking in the kitchen to complex industrial reactions.

Match the vocabulary on the left with the correct definition on the right:

• Reactant: A substance that undergoes a change in a chemical reaction.
• Subscript: A number written below and to the right of a chemical symbol indicating the number of atoms of that element in a molecule.
• Product: A substance formed as a result of a chemical reaction.
• Coefficient: A number placed in front of a chemical formula in a balanced chemical equation to indicate the number of molecules of that compound.

Complete the activity based on the formula for Sulfuric acid (H₂SO₄):

• Drop target 1: H (Hydrogen)
• Drop target 2: S (Sulfur)
• Drop target 3: O (Oxygen)

---

Based on the formula for Sulfuric acid (H₂SO₄), there are

• 1 molecule of sulfuric acid. In each molecule there are
• 2 hydrogen atoms (H),
• 1 sulfur atom (S), and
• 4 oxygen atoms (O). This means that there are
• 7 atoms total in this substance.

Label the parts of a chemical equation:

Use these labels for the corresponding drop targets in the image of the chemical equation:

• Drop target 1: Reactants (substances that start the reaction)
• Drop target 2: Products (substances formed by the reaction)
• Drop target 3: Coefficients (numbers in front of compounds that indicate the number of molecules)
• Drop target 4: Arrow (indicates the direction of the reaction, usually read as "react to form")
