Study of the chemical equation ⚖️ for complete methane combustion CH₄ 🔥

1. A reactant is a substance consumed during a chemical transformation 🧪.
TRUE FALSE

2. The arrow shows the direction of the chemical transformation, from reactants to products.
TRUE FALSE

3. The products are on the left of the arrow, and the reactants are on the right.
TRUE FALSE

4. There are two reactants: methane CH₄ and dioxygen O₂.
TRUE FALSE

5. The methane molecule CH₄ contains one hydrogen atom H and four carbon atoms C.
TRUE FALSE

6. 2O₂ means two dioxygen molecules, so 4 oxygen atoms O.
TRUE FALSE

7. CH₄ contains 1 carbon atom C, and 2O₂ contains none.
Therefore CH₄ + 2O₂ contains 1 carbon atom.
TRUE FALSE

8. CO₂ contains no hydrogen atom H, and 2H₂O contains 4.
Therefore CO₂ + 2H₂O contains 4 hydrogen atoms H.
TRUE FALSE

9. CO₂ contains 2 oxygen atoms O, and 2H₂O contains 2.
Therefore CO₂ + 2H₂O contains 4 oxygen atoms O.
TRUE FALSE

10. This chemical equation is balanced because there are 4 carbon atoms, 4 hydrogen atoms, and 4 oxygen atoms before and after the arrow.
TRUE FALSE
