  1. How many moles of oxygen gas is required to completely react with 50g of CH4

  • Step 1: Write the balanced chemical equation for the combustion of methane.

    CH4(g)+2O2(g)⟶CO2(g)+2H2O(l)\text{CH}_4(g) + 2\text{O}_2(g) \longrightarrow \text{CO}_2(g) + 2\text{H}_2\text{O}(l)

  • Step 2: Calculate the molar mass of CH4\text{CH}_4. Molar mass of C = 12.01 g/mol12.01 \text{ g/mol} Molar mass of H = 1.008 g/mol1.008 \text{ g/mol} Molar mass of $\text{
