Study of the chemical equation ⚖️ for complete butane combustion C₄H₁₀ 🔥

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

2. The “+” sign separates the reactants from the products. There are two reactants and two products.
TRUE FALSE

3. The reactants are on the left of the arrow. They are dioxygen and butane.
TRUE FALSE

4. This balanced chemical equation contains 8 carbon dioxide molecules.
TRUE FALSE

5. In this chemical equation, there are eight butane molecules.
TRUE FALSE

6. The product containing hydrogen atoms is butane. There are two butane molecules, so there are 20 hydrogen atoms on the products side.
TRUE FALSE

7. Both products contain oxygen atoms.
8CO₂ → 8 × 1 = 8 oxygen atoms
10H₂O → 10 × 2 = 20 oxygen atoms.
Therefore a total of 8 + 20 = 28 oxygen atoms.
TRUE FALSE

8. Before and after the arrow, there are eight carbon atoms.
TRUE FALSE

9. Before and after the arrow, there are 26 oxygen atoms.
TRUE FALSE

10. This chemical equation is balanced because there are 8 carbon atoms C, 20 hydrogen atoms H, and 26 oxygen atoms O before and after the arrow.
TRUE FALSE
