10 of 10 Submit 1 Balancing Chemical Reactions Balance the reaction and answer the questions. \[ -\mathrm{C}_{2} \mathrm{H}_{6}+-\mathrm{O}_{2} \rightarrow-\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \] PART A The reaction here shows a simple chemical reaction involving the combustion of ethane \( \left(\mathrm{C}_{2} \mathrm{H}_{6}\right) \), a fuel, in the presence of oxygen gas to form water and carbon dioxide \( \left(\mathrm{CO}_{2}\right) \). Which coefficients can be placed in the blanks to correctly balance the equation? A \( 1,3,2,3 \) B \( 2,7,4,6 \) C \( \quad 2,6,4,7 \) D \( \quad 2,4,3,2 \) PART B

When balancing this combustion reaction, you’ll want to ensure that the number of each type of atom is the same on both sides. Starting with ethane \( \mathrm{C}_{2}\mathrm{H}_{6} \), it contains 2 carbon atoms and 6 hydrogen atoms. When burned, it produces \( \mathrm{CO}_{2} \) and \( \mathrm{H}_{2}\mathrm{O} \). By trial and error, you can determine that the balanced equation is: \[ 2\mathrm{C}_{2}\mathrm{H}_{6} + 7\mathrm{O}_{2} \rightarrow 4\mathrm{CO}_{2} + 6\mathrm{H}_{2}\mathrm{O} \] This means the correct coefficients are from option C: \( 2, 7, 4, 6 \). In real-world applications, combustion reactions like this one are paramount in different fields such as energy production, transportation, and heating. Ethane combustion is essential not just for generating power but also for understanding pollution control since it produces carbon dioxide, a greenhouse gas. It's like a chemistry lesson every time you fill up your car or turn on the heater; knowing what's going on chemically can make every drive feel a bit more interesting!
