The question is incomplete. The complete question is :
Drag the tiles to the correct boxes to compete the pairs. Identify the types of chemical reactions occurring in the chemical equations.
combustion reaction
, photosynthesis
, respiration
water + carbon dioxide + sunlight → oxygen + glucose
methane + oxygen → water + carbon dioxide + heat
glucose + oxygen → carbon dioxide + water + energy
Solution :
The chemical reactions that is occurring in the following chemical equations are :
<u>Photosynthesis</u>
water + carbon dioxide + sunlight → oxygen + glucose
Plants uses the light energy from the sun in the presence of water and carbon dioxide produces food by the process of photosynthesis. It produces glucose and oxygen.
<u>Respiration</u>
glucose + oxygen → carbon dioxide + water + energy
The cellular respiration process produces ATP with the breakdown of the glucose and oxygen. During respiration process, carbon dioxide is obtained along with water and energy.
<u>Combustion reaction</u>
methane + oxygen → water + carbon dioxide + heat
Combustion reaction is a chemical reaction in which methane is the main ingredient. Combustion takes place as things burn in the presence to methane and oxygen to form carbon dioxide, water and heat.
