Question

the reactants and products of cellular respiration are made of the same amounts of hydrogen, carbon, and oxygen atoms. when 1 molecule of glucose (c₆h₁₂o₆) reacts with 6 molecules of oxygen gas (o₂), the atoms in those molecules are rearranged to produce 6 molecules of carbon dioxide gas (co₂) and 6 molecules of water (h₂o). which chemical equation is balanced and represents the overall process of cellular respiration? c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o 6c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o 6c₆h₁₂o₆ + o₂ → 6co₂ + h₂o c₆h₁₂o₆ + 6o₂ → co₂ + 6h₂o

Explanation:

Step1: Count atoms in reactants

For \(C_6H_{12}O_6+6O_2\), carbon atoms \(= 6\), hydrogen atoms \(= 12\), oxygen atoms \(=6 + 6\times2=18\).

Step2: Count atoms in products

For \(6CO_2 + 6H_2O\), carbon atoms \(=6\times1 = 6\), hydrogen atoms \(=6\times2=12\), oxygen atoms \(=6\times2+6\times1 = 18\).

Answer:

\(C_6H_{12}O_6+6O_2\to6CO_2 + 6H_2O\)
