1/18뒤로Skip to main content뒤로Which reaction is exothermic?
Exothermic reactions are those that release thermal energy, such as condensation, freezing, and deposition. What is an accurate statement about exothermic reactions?
Exothermic reactions release thermal energy, causing molecules to slow down and form bonds, and they feel warm to the touch. How is energy used in chemical reactions?
D) Both A and B Which reaction is an example of an endergonic reaction?
A) Melting of ice For an exothermic solution, what happens to the enthalpy change (ΔH)?
For an exothermic solution, the enthalpy change (ΔH) is negative, indicating that energy is released. What is the basic difference between exergonic and endergonic reactions?
Exergonic reactions release energy, while endergonic reactions absorb energy. What is an example of an endergonic reaction?
Photosynthesis Which chemical reaction releases energy?
Combustion What is an example of an endergonic process?
