The volume of ethane gas, C₂H₆ in cm³ that will react to produce 40 cm³ of CO₂ is 20 cm³
<h3>Balanced equation </h3>
2C₂H₆ + 7O₂ —> 4CO₂ + 6H₂O
From the balanced equation above,
4 cm³ of CO₂ were obtained from 2 cm³ of C₂H₆
<h3>How to determine the volume of C₂H₆ needed </h3>
From the balanced equation above,
4 cm³ of CO₂ were obtained from 2 cm³ of C₂H₆
Therefore,
40 cm³ of CO₂ will be obtain from = (40 × 2) / 4 = 20 cm³ of C₂H₆
Thus, 20 cm³ of C₂H₆ are required for the reaction.
