    Explanation:

    Step 1:

    The balanced equation for the reaction between gaseous ethane and gaseous oxygen. This is given below:

    2C2H6 + 7O2 - > 4CO2 + 6H2O

    Step 2:

    Determination of the masses of C2H6 and O2 that reacted and the mass of CO2 produced from the balanced equation. This is illustrated below:

    2C2H6 + 7O2 - > 4CO2 + 6H2O

    Molar Mass of C2H6 = (12x2) + (6x1) = 24 + 6 = 30g/mol

    Mass of C2H6 from the balanced equation = 2 x 30 = 60g

    Molar Mass of O2 = 16x2 = 32g/mol

    Mass of O2 from the balanced equation = 7 x 32 = 224g

    Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol

    Mass of CO2 from the balanced equation = 4 x 44 = 176g

    From the balanced equation above,

    60g of C2H6 reacted with 224g of O2 to produce 176g of CO2.

    Step 3:

    Determination of the limiting reactant.

    We need to determine the limiting reactant as it will be needed to obtain the maximum mass of CO2.

    From the balanced equation above,

    60g of C2H6 reacted with 224g of O2.

    Therefore, 2.71g of C2H6 will react with = (2.71 x 224) / 60 = 10.12g of O2.

    From the above calculation, we can see that a higher mass of O2 is needed to react with 2.71g of C2H6, therefore, O2 is the limiting reactant.

    Step 4:

    Determination of the maximum mass of CO2 produced when 2.71 g of ethane is mixed with 7.6 g of oxygen.

    The limiting reactant is used to determine the maximum mass.

    From the balanced equation above,

    224g of O2 produce 176g of CO2.

    Therefore, 7.6g of O2 will produce = (7.6 x 176) / 224 = 5.97g ≈ 6g of CO2

    From the calculations made above, the maximum mass of CO2 produced is 5.97 ≈ 6g
