Photosynthesis is the process utilized in the chloroplasts of plant cells, where carbon dioxide and water undergo a chemical process with radiant energy, usually from the sun. The resulting products are energy stored in the form of a glucose molecule, and oxygen, which is given off as a waste product.
Answer:
3.38 moles of O2.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
4CH2OH + 5O2 → 4CO2 + 6H2O
From the balanced equation above,
4 moles of CH2OH required 5 moles of O2 for complete combustion.
Finally, we shall determine the number of mole of O2 needed to react with 2.7 moles of CH2OH. This can be obtained as follow:
From the balanced equation above,
4 moles of CH2OH required 5 moles of O2 for complete combustion.
Therefore, 2.7 moles of CH2OH will require = (2.7 × 5)/4 = 3.38 moles of O2 for complete combustion.
Thus, 3.38 moles of O2 is required.

The products and the reactants are the components of the reaction. The equation of phosphoric acid represents the decomposition reaction as it forms oxygen and water. Thus, option a is correct.
<h3>What is a decomposition reaction?</h3>
A decomposition reaction is a chemical breakdown of the reactant into two or more products. The large and complex compound breaks into smaller and simpler molecules.
The following equation, 4 H₃PO₄ → P₄ + 5 O₂ + 6 H₂O is an example of decomposition as phosphoric acid breaks into phosphorus, water, and oxygen molecules.
Therefore, option a. the reaction of phosphoric acid is a decomposition reaction.
