Cuando se queman combustibles que tienen algún compuesto de azufre se produce dióxido de azufre (), un gas irritante que puede provocar lluvia ácida. En el análisis del aire de una ciudad se ha encontrado una concentración de de 14 .
¿Qué cantidad de habrá en 1 L de aire?

c is the answer because when something is left after something evaporates that shows the chemical change.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

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.
