Which statements apply to food storage medium for energy absorb energy during assimilation release energy during decomposition energy released during photosynthesis?
Food storage mediums, such as carbohydrates and fats, absorb energy during assimilation when organisms take in nutrients and convert them into usable forms. They release energy during decomposition as microorganisms break them down, which is essential for nutrient cycling in ecosystems. Additionally, energy is released during photosynthesis, but this process primarily involves converting light energy into chemical energy stored in food, rather than being a characteristic of food storage mediums themselves.
During a temperature change what is happening to the substance?
A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.
What is a breakdown of substances into simpler molecules called?
The breakdown of substances into simpler molecules is called catabolism. During catabolism, larger molecules are broken down into smaller ones, releasing energy in the process.
Name a photolytic reaction that is not a decomposition reaction?
One example of a photolytic reaction that is not a decomposition reaction is the photolysis of water during photosynthesis. In this reaction, light energy is used to split water molecules into oxygen, hydrogen ions, and electrons, which are then used in the production of energy-rich molecules like ATP and NADPH.
Why all decomposition reaction are endothermic reaction?
Not all decomposition reactions are endothermic; however, many are because they require energy to break chemical bonds. In an endothermic decomposition reaction, the energy absorbed from the surroundings is used to overcome the energy barriers of the bonds in the reactants, leading to the formation of new products. Examples include the thermal decomposition of calcium carbonate into calcium oxide and carbon dioxide, which requires heat. Conversely, some decomposition reactions can be exothermic, releasing energy, depending on the specific reactants and conditions involved.
Is energy absorbed or released during a decomposition reaction?
Energy is often absorbed during a decomposition reaction because the reactant breaks down into smaller molecules or atoms. This process typically requires energy input to break the existing chemical bonds.

Why is the molar enthalpy of the decomposition of that compound 192 kJ?
The molar enthalpy of the decomposition of a compound can be 192 kJ due to the energy required to break the bonds within the compound during the decomposition process. This energy is released as heat. The specific value of 192 kJ would depend on the specific compound being decomposed and the bonds involved.
Do decomposition reactions require energy?
Decomposition reactions usually release energy, as they involve breaking down a compound into simpler substances. This energy release can be in the form of heat, light, or sound. However, some decomposition reactions may require activation energy to start the process.
What is happening to particle motion and thermalheat energy during melting?
Particle motion and thermal heat energy should both be increasing
What is meant by decomposition potential?
Decomposition potential refers to the tendency of a substance to break down into simpler components under certain conditions, such as during a chemical reaction or electrolysis. It is a measure of the energy required to initiate the decomposition process.
What are the harmful effects of decomposition?
Methane gas is released, as well as carbon dioxide, during decomposition.
Name a photolytic reaction that is not a decomposition reaction?
One example of a photolytic reaction that is not a decomposition reaction is the photolysis of water during photosynthesis. In this reaction, light energy is used to split water molecules into oxygen, hydrogen ions, and electrons, which are then used in the production of energy-rich molecules like ATP and NADPH.
What does a substance break down into during a decomposition reaction?
A substance breaks down into two or more simpler substances during a decomposition reaction.
How hot can compost get during the decomposition process?
Compost can reach temperatures of up to 160-170 degrees Fahrenheit during the decomposition process.
