Consider the reaction:

\[ \text{CH}_4 + 2 \text{O}_2 \rightarrow \text{CO}_2 + 2 \text{H}_2\text{O} \]

Select the true statement:

1. 4.00 moles of CH4 will react with 2.00 moles of O2.
2. The limiting product is CO2.
3. The limiting reactant is CO2.
4. 8.00 moles of O2 can react to produce 144.0 g of H2O.
5. 4.00 moles of O2 can react to produce 4.00 moles of CO2.
6. 88.01 g of CO2 could be produced upon reaction of 64.00 g of O2.

Answer :

5. 4.00 moles of O2 can react to produce 4.00 moles of CO2.

What is the relationship between moles of O2 and moles of CO2?

  • The balanced chemical equation shows that 1 mole of CH4 reacts with 2 moles of O2 to produce 1 mole of CO2 and 2 moles of H2O.
  • Therefore, 4 moles of CH4 would react with 8 moles of O2 to produce 4 moles of CO2.
  • Since the ratio of O2 to CO2 is 2:1, 4 moles of O2 would react with 2 moles of CH4 to produce 2 moles of CO2.
  • Therefore, statement 5 is true: 4.00 moles of O2 can react to produce 4.00 moles of CO2.

According to the balanced chemical equation, the ratio of moles of O2 to moles of CO2 is 2:1, which means that 4 moles of O2 would react with 2 moles of CH4 to produce 2 moles of CO2. Therefore, statement 5 is true.
