Explanation:

Chemical reaction

Facts are core properties of chemical reactions; examples are real-world instances of these reactions.

Atoms

Facts cover fundamental traits of atoms; examples are specific types or uses of atoms.

Conservation

Facts focus on the core principle of conservation in chemistry; examples are real applications of this principle.

Reactant

Facts describe the role/features of reactants; examples are specific substances acting as reactants.

Answer:

Chemical reaction

1. Fact: Rearranges atomic bonds
2. Fact: Produces new substances
3. Example: Rusting of iron ($4\text{Fe} + 3\text{O}_2

ightarrow 2\text{Fe}_2\text{O}_3$)

1. Example: Burning methane ($\text{CH}_4 + 2\text{O}_2

ightarrow \text{CO}_2 + 2\text{H}_2\text{O}$)

1. Example: Baking soda + vinegar reaction

Atoms

1. Fact: Basic unit of all matter
2. Fact: Has a nucleus with protons/neutrons
3. Example: Hydrogen atom (1 proton, 0 neutrons)
4. Example: Carbon-12 atom (6 protons, 6 neutrons)
5. Example: Oxygen atom (8 protons, 8 neutrons)

Conservation

1. Fact: Mass is not created/destroyed
2. Fact: Applies to closed chemical systems
3. Example: Burning wood (mass of ash+gases = wood+oxygen)
4. Example: Dissolving salt in water (total mass stays same)
5. Example: Iron rusting (mass of rust = iron+oxygen)

Reactant

1. Fact: Starts a chemical reaction
2. Fact: Gets consumed during reaction
3. Example: Hydrogen gas in water synthesis
4. Example: Oxygen gas in combustion reactions
5. Example: Vinegar in baking soda reaction
