What is not a good laboratory method for the preparation of oxygen? A)photosynthesis of sugars: 6 CO₂(g)+ 6 H₂O(l)→ 6 O₂(g)+ ₆H₁₂O₆(s) B)electrolysis of water: 2 H₂O(l)→ 2 H₂(g)+ O₂(g) C)catalytic decomposition of hydrogen peroxide: 2 H₂O₂(aq)→ 2 H₂O(l)+ O₂(g) D)thermal decomposition of potassium chlorate: 2 KClO₃(s)→ 2 KCl(s)+ 3 O₂(g)

Question

Quizplus · Accepted Answer

Photosynthesis of sugars is not a laboratory method for the preparation of oxygen. This is a natural process that occurs in plants and algae where they use sunlight, water, and carbon dioxide to produce glucose and oxygen. The other options (B, C, and D) are valid laboratory methods for preparing oxygen.
