To analyze the given chemical reaction:
\[ \text{C}_3\text{H}_8 + 5\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O} \]
Let's break down the stoichiometric ratios:
1. For every 1 mole of propane (C3H8) that reacts, 5 moles of oxygen (O2) are needed.
2. For every 1 mole of propane that reacts, 3 moles of carbon dioxide (CO2) are produced.
3. For every 1 mole of propane that reacts, 4 moles of water (H2O) are produced.
Now, let's evaluate the options provided in your question:
1. **For each mole of oxygen that reacts, 3 moles of carbon dioxide are produced.**
- This is incorrect. The ratio implies that 1 mole of oxygen yields 3 moles of CO2, which is not true since 5 moles of oxygen yield 3 moles of CO2.
2. **For every 3 moles of carbon dioxide produced, 5 moles of oxygen react.**
- This is correct. The ratio can be derived from the equation: 3 moles of CO2 are produced from 5 moles of O2.
3. **For every 4 moles of water produced, 3 moles of propane react.**
- This is also correct. The equation shows 4 moles of water produced from 1 mole of propane, but if we reverse this, we can say for every 4 moles of water produced, 1 mole of propane reacts, which is still consistent.
4. **For each mole of propane that reacts, 5 moles of oxygen are produced.**
- This is incorrect. The equation shows that 5 moles of oxygen are consumed (not produced) per mole of propane.
Considering these evaluations, the correct statements are:
- **For every 3 moles of carbon dioxide produced, 5 moles of oxygen react.**
- **For every 4 moles of water produced, 3 moles of propane react.**
If only one response is needed, the most direct and correct would be: **For every 3 moles of carbon dioxide produced, 5 moles of oxygen react.**
