Mr. thorton, the science teacher, was explaining the difference between kinetic and potential energy. he compared the difference to a wind-up toy. he said, "kinetic energy is like a wind-up toy that is let go and is moving but potential energy is when the wind-up toy is wound up but not released yet." what misconception may come from this analogy?

answer is d (An object with kinetic energy can only move for a certain amount of time and then it stops.)

Explanation:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
