Question

supoose 10 atoms of carbon react with 20 atoms of oxygen to form 10 molecules of carbon dioxide

Answer 1

In this reaction, 10 atoms of carbon (C) react with 20 atoms of oxygen (O) to form 10 molecules of carbon dioxide (CO₂).

### Balanced Reaction:

The chemical equation representing this reaction can be written as:

\[
C + O_2 \rightarrow CO_2
\]

### Molecules Involved:

- Each molecule of carbon dioxide (CO₂) consists of 1 carbon atom and 2 oxygen atoms.
- Therefore, to produce 10 molecules of CO₂, we need:
- 10 carbon atoms (since each CO₂ contains 1 C)
- 10 oxygen molecules (since each CO₂ contains 2 O, so \(10 \text{ CO}_2 \times 2 \text{ O} = 20 \text{ O}\))

### Summary of the Reaction:

- **Reactants:**
- 10 carbon atoms (C)
- 20 oxygen atoms (O)

- **Products:**
- 10 molecules of carbon dioxide (10 CO₂)

This scenario accurately describes a balanced chemical reaction, demonstrating that the law of conservation of mass is upheld, as the number of atoms on both sides of the equation is the same.
