Question

energy changes in chemical reactions: tutorial. drag the tiles to the correct boxes to complete the pairs. match each term to its definition. tiles: respiration, photosynthesis, electrochemical reaction, combustion. pairs: a reaction that releases energy in the form of an electric current, a reaction that uses oxygen and releases heat and light energy, a reaction in which plants absorb energy from the sun

Explanation:

• An electrochemical reaction releases energy in the form of an electric current.
• Combustion is a reaction that uses oxygen and releases heat and light energy.
• Photosynthesis is a reaction in which plants absorb energy from the Sun.

Answer:

• a reaction that releases energy in the form of an electric current → electrochemical reaction
• a reaction that uses oxygen and releases heat and light energy → combustion
• a reaction in which plants absorb energy from the Sun → photosynthesis
