What else can I help you with?
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.
Is NOBr decomposition exothermic or endothermic?
The decomposition of NOBr is endothermic, meaning it requires an input of energy to break down the compound into its constituent elements (NO and Br₂).
Does compost release CO2 during the decomposition process?
Yes, compost releases carbon dioxide (CO2) during the decomposition process as organic matter breaks down.
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.
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.

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.
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.
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.
How hot does compost get during the decomposition process?
Compost can reach temperatures between 120 to 160 degrees Fahrenheit during the decomposition process.
