Question

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

Explanation:

Step1: Count atoms in reactants

For \(6CO_{2}+6H_{2}O\):

• Carbon: \(6\times1 = 6\)
• Hydrogen: \(6\times2=12\)
• Oxygen: \((6\times2)+(6\times1)=12 + 6=18\)

Step2: Count atoms in products for \(C_{6}H_{12}O_{6}+6O_{2}\)

• Carbon: \(6\)
• Hydrogen: \(12\)
• Oxygen: \(6+(6\times2)=6 + 12=18\)

Answer:

\(6CO_{2}+6H_{2}O
ightarrow C_{6}H_{12}O_{6}+6O_{2}\)
