Heat is released when h2 gas and o2 gas react to form h2o. why?
a. breaking the h–h bond in h2 gas releases heat.
b. breaking the o–o bond in o2 gas releases heat.
c. forming the h–o bonds in h2o releases heat.
d. both a and b are responsible for heat being released in the reaction.
i guessed d

girl imma just put my comment here because i need a couple point okurrttt

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
