Question

which is the word equation for photosynthesis?
carbon + hydrogen + oxygen → glucose + water
glucose + water → carbon dioxide + oxygen
carbon dioxide + water → glucose + oxygen
glucose + oxygen → carbon + water + oxygen

Explanation:

Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into glucose (a sugar) and oxygen. Option C correctly represents this process. Option A is incorrect as carbon, hydrogen, and oxygen are elements not reactants in the photosynthesis equation. Option B has the reactants and products reversed (it resembles the reverse of photosynthesis). Option D also has incorrect reactants and products.

Answer:

C. carbon dioxide + water → glucose + oxygen
