Almost all hydrocarbon 'burn' reactions involve oxygen; it's by far the most reactive substance in air. 

<span>Hydrocarbon combustions always involve </span>
<span>[some hydrocarbon] + oxygen --> carbon dioxide + steam. </span>

C6H6(l) + O2 (g)--> CO2 (g)+ H2O (g)

<span>Balance carbon, six on each side: </span>
C6H6(l) + O2 (g)--> 6CO2 (g)+ H2O (g)

<span>Balance hydrogen, six on each side: </span>
C6H6(l) + O2 (g)--> 6CO2(g) + 3H2O (g)

<span>Now, we have fifteen oxygens on the right and O2 on the left. </span>
<span>Two ways to deal with that. We can use a fraction: </span>
C6H6 (l)+ (15/2)O2 (g)--> 6CO2 (g)+ 3H2O (g)

<span>Or, if you prefer to have whole number coefficients, double everything </span>
<span>to get rid of the fraction: </span>
2C6H6 (l)+ 15O2 (g)--> 12CO2 (g)+ 6H2O (g)

<span>With the SATP states thrown in... </span>
C6H6(l) + (15/2)O2(g) --> 6CO2(g) + 3H2O(g)

Which of the following equations represents Photosynthesis? 16CO2 + 6H2O -----&gt; C6H12O6 + 6O22C6H12O6 + 6O2 -----&gt; CO2 + 6
lidiya [134]

Answer:

  • 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Explanation:

<em>Photosynthesis</em> is the chemical process carried out by plants for the conversion of inorganic matter (carbon dioxide and water) into organic matter (glucose) with the release of oxygen, using light (sun energy).

So the chemical process may be represented by:

  • <u>Word equation: </u>

        carbon dioxide + water + sun energy → glucose + oxygen

  • <u>Skeleton equation:</u>

       CO₂ + H₂O + sun energy → C₆H₁₂O₆ + O₂

  • <u>Balanced chemical equation:</u>

       6CO₂ + 6H₂O + sun energy → C₆H₁₂O₆ + 6O₂

  • <u>Supressing the energy to show only the chemical compounds:</u>

        6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
