Which of the following chemicals is implicated in both global warming and ozone depletion? a. chlorofluorocarbons b. sulfur dioxide c. nicotine d. radon

A

Explanation:

Chlorofluorocarbons generally abbreviated as CFCs are a group of organic chemicals used in several household and industrial materials and are responsible for global warming and ozone depletion.

Global warming is the general increase in the atmospheric temperature of the earth continually over the years. It is a direct consequence of climate change which is caused by the continuous release of green house gases into the atmosphere which trap radiated heat from the sun.

Ozone depletion involves anthropogenic activities which lead to decreasing the natural spread of the ozone layer which prevents the direct contact between the sun UV radiation and the earth.

CFCs are implicated in both cases as they are responsible for the two I.e they cause global warming and also deplete the ozone layer. Years back they are basically used in most aerosol cans like perfumes spray, insecticide spray etc. However as a result of the increased knowledge of their dangers, there had been legislations which had cut down on their continuous usage with alternatives being used

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.
