What causes damage to the ozone layer? jenny has appealed to the local government to ban the use of aerosol room fresheners because they contain which can damage the ozone layer.

The right answer is chlorofluorocarbons (CFCs).

A good aerosol propellant must be odorless, colorless and non-flammable. CFCs, chlorofluorocarbons, have been used for many years. Unfortunately, they would have actively participated in the destruction of the ozone layer. Their use was banned in 1985 by the Montreal Protocol. Other often flammable substitutes (for example butane or propane) have been found.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
