Draw the Lewis structure of carbonic acid, H2CO3. Use formal charge to prove you have a favorable structure. Use resonance to show how the carbonate ion is stabilized. How many resonance structures are required to describe the carbonate ion (count all the main contributors)?

the dependant variable is spilled water

the independent is the heat

i think it is true since you can test the answer and can use observations to complete it.

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.

gas

explanation:

smoke is the matter of a gas
