What is the relationship between exothermic reactions and entropy changes in a chemical system?
In a chemical system, exothermic reactions release heat energy, while entropy changes refer to the disorder or randomness of molecules. Exothermic reactions typically lead to an increase in entropy, as the released heat energy can increase the movement and randomness of molecules in the system.

What is the relationship between the formation reactions that are exothermic and their corresponding enthalpy of formation values (hf)?
The relationship between exothermic formation reactions and their enthalpy of formation values is that exothermic reactions release heat energy when the compound is formed. This results in a negative enthalpy of formation value (hf) because the reaction is giving off energy.
What chemical reactions are exothermic?
Any chemical reaction that produces energy is exothermic. A erection that requires energy is endothermic. For instance, NaCl + H20 -> HCl + NaOH is endothermic. Run the equation the opposite direction, HCl _+ NaOH -> NaCl + H20 and it's an exothermic reaction.
Does exothermic chemical reactions absorb heat?
it depend on endothermic and exothermic reactions . whenever bonds are breaked to form new products energy is absorbed e.g CaCO3 break down to CaO and CO2 if u heat it but on the other hand bond forming is the process in which heat is released e.g when Na and Cl combines energy is released and the product formed is NaCl .
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
How is exothermic reactions related to chemical energy?
Heat energy is directly related to chemical interactions. As heat energy increases, chemical interactions also will due to the increased kinetic energy and therefore interactions of particles.
What is the diffrencence between exothermic reaction and chemical reaction?
A chemical reaction is a process that involves the breaking and forming of chemical bonds to create new substances. An exothermic reaction is a type of chemical reaction that releases heat energy to the surroundings. In other words, all exothermic reactions are chemical reactions, but not all chemical reactions are exothermic.
What is the relationship between the formation reactions that are exothermic and their corresponding enthalpy of formation values (hf)?
The relationship between exothermic formation reactions and their enthalpy of formation values is that exothermic reactions release heat energy when the compound is formed. This results in a negative enthalpy of formation value (hf) because the reaction is giving off energy.
What is the relationship between the temperature and the rate of chemical?
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..
What are some example of exothermic reaction?
Exothermic Chemical Reactions · mixing sodium and chlorine to yield table salt · Respiration; combustion of fuels; and neutralization reactions between acids and alkali's

Is combustion a physio-chemical reaction?
Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species.
What is one similarity between exothermic reaction and an endothermic reaction?
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.

Who determined the relationship between atomic weight and weight relations in chemical reactions?
Not sure.
What is the relationship between proteins and enzyme?
Enzymes are Proteins that speed up chemical reactions.
