Though energy cannot be created or destroyed, it can be transferred and transformed. When energy is not in use, it can be stored Chemical energy is stored in chemical compounds and released through chemical reactions. Think about the ways you have used stored

chemical energy

Which are true statements about how chemical energy can be stored and released through chemical reactions?

The question is incomplete as the options are not given but the options is gotten from another websites.

1 .As bike tires roll across the sidewalk, friction is created and they become warmer.

2. Solar energy from the sun is absorbed by solar panels, which transforms to chemical energy when it is used as electricity.

3. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.

4. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.

5. Thermal energy causes energy stored in fireworks to convert to kinetic, light, and sound energy.

The correct options are 3 and 4.

3. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.

4. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.

Explanation:

Chemical energy is stored in food but when the food is broken down into smaller pieces or nutrients by the process of digestion, chemical energy are released which is use to drive different body functions or mechanisms.

Chemical energy are stored in circuits. When these circuits are connected to battery, the chemical energy are released and these energy are then converted to electrical energy to produce heat or light .
