The correct answer is C. Photosynthesis.

Explanation

Endothermic reactions are a chemical and physical term used to refer to the process of transformation of two or more substances into different ones, and that particularly consume energy, that is, that the resulting elements have higher energy levels than the initial elements, due to that have taken part of the heat of the environment. According to the above, photosynthesis is an endothermic reaction since plants absorb solar energy, to perform various processes that allow them to make their food, grow and generally live. So, the correct answer is C. Photosynthesis.

The reaction for photosynthesis producing glucose sugar and oxygen gas is:

uranmaximum [27]

Answer:

a. 1.12 L

Explanation:

Step 1: Write the balanced equation for the photosynthesis

6 CO₂(g) + 6 H₂O(l) ⇒ C₆H₁₂O₆(s) + 6 O₂(g)

Step 2: Calculate the moles corresponding to 2.20 g of CO₂

The molar mass of CO₂ is 44.01 g/mol.

2.20 g × 1 mol/44.01 g = 0.0500 mol

Step 3: Calculate the moles of O₂ produced

The molar ratio of CO₂ to O₂ is 6:6. The moles of O₂ produced are 6/6 × 0.0500 mol = 0.0500 mol

Step 4: Calculate the volume occupied by 0.0500 moles of O₂ at STP

At STP, 1 mole of O₂ occupies 22.4 L.

0.0500 mol × 22.4 L/1 mol = 1.12 L
