Question

drag the tiles to the correct boxes to complete the pairs. identify the types of chemical reactions occurring in the chemical equations. respiration photosynthesis combustion reaction of fossil fuels methane + oxygen → water + carbon dioxide + heat glucose + oxygen → carbon dioxide + water + energy water + carbon dioxide + sunlight → oxygen + glucose

Explanation:

1. Methane reacting with oxygen to produce water, carbon - dioxide and heat is a combustion reaction of a fossil fuel (methane is a fossil fuel).
2. Glucose reacting with oxygen to produce carbon - dioxide, water and energy is the process of respiration in living organisms.
3. Water and carbon - dioxide using sunlight to produce oxygen and glucose is the process of photosynthesis in plants.

Answer:

methane + oxygen → water + carbon dioxide + heat: combustion reaction of fossil fuels
glucose + oxygen → carbon dioxide + water + energy: respiration
water + carbon dioxide + sunlight → oxygen + glucose: photosynthesis
