What else can I help you with?
What heat transfer associated with a chemical reaction or pharse changs as either exthermic or endothermic?
to see your mom.
Is a road flare exthermic or endothermic?
Exothermic, because it releases heat as a form of energy.
What statement describes the potential energy diagram of an exthermic reaction?
In an exothermic reaction, the potential energy diagram shows a decrease in potential energy as the reactants transform into products. The reactants have higher energy compared to the products, indicating that energy is released during the reaction, often in the form of heat. The diagram typically features a downward slope from the reactants to the products, with an activation energy barrier that must be overcome for the reaction to proceed. Overall, this results in a negative change in enthalpy (ΔH).
What H2O(l) plus heat H2O(g) exthermic or endothermic?
It is an exothermic reaction. There are multiple ways to think about this. The reactants are in the gas phase and thus have a lot of energy within the molecules. When they react to produce a liquid, which has much less energy in its molecules. The energy must be released to the environment to lower the energy of the bonds.
