WebEnergy can change forms in a similar way in living organisms. For instance, energy stored in bonds of the small molecule ATP (potential energy) can power the movement of a motor protein and its cargo along a microtubule track, or the contraction of muscle cells to … Web2 Cu (s) + O 2 (g) → 2 CuO (s) ΔH° = -310 kJ. 2 Cu (s) + 1/2 O 2 (g) → Cu 2 O (s) ΔH° = -169 kJ. Click here for the answer: Hess’ Law can be shown visually through an enthalpy diagram. The one shown here represents the above reaction. The change in enthalpy, ΔH, is represented by the distance between the horizontal lines.

This chemical change releases energy as …
WebThe changes in energy that occur during a chemical reaction can be seen by examining the changes in chemical bonding. This can be used to classify reactions as exothermic or endothermic. WebYes. It comes from the understanding that chemical equations can be treated like algebraic equations, with the arrow acting like the equals sign. Like algebraic equations, chemical equations can be combined, and if the same substance appears on both sides of the arrow, it can be canceled out (much like a spectator ion in ionic equations).
