You decide to establish a new temperature scale on which the melting point of ammonia (-77.75 ∘c) is 0∘a, and the boiling point
Hoochie [10]
First we need to know that the boiling point of water in C is 100 and we just need to solve for x in the equation:

-33.75-(-77.75) / 100 = 100-(-77.75) / x
44.4/100 = 177.75 / x
 x = 177.75*100/44.4 = 400.33

The boiling point of water in ∘a would be 400.33∘a.

Which of the following equations represents Photosynthesis? 16CO2 + 6H2O -----> C6H12O6 + 6O22C6H12O6 + 6O2 -----> 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
