PLEASE HELP! The compound Tetrahydrocannabinol (the psychoactive component in marihuana) is C2 H2002 What is the valence count? (as in total number of valance electrons for this compound. (Hint: We talked about this when we discussed Lewis structures) O 140 O 110 O 130 O 120

110 is the answer buddy..

the dissolution of polymer can be thermodynamically described in 2 steps.

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.
