What is the chemical equation of CFCs destroying the ozone?

Cl + O3 = ClO + O2 When the molecule of chlorine monoxide (ClO) meets another molecule of oxygen (O) it breaks up, releasing chlorine (Cl), which can “destroy” another molecule of ozone (O3), creating the catalytic cycle of chlorine.

What is ozone layer depletion write the equation of ozone?

The ozone layer is created when ultraviolet rays react with oxygen molecules (O2) to create ozone (O3) and atomic oxygen (O). This process is called the Chapman cycle. Step 1: An oxygen molecules is photolyzed by solar radiation, creating two oxygen radicals: hν+O2→2O.

What is the formula of chlorofluorocarbon?

Chlorofluorocarbons, such as dichlorodifluoromethane (CCl2F2), and trichlorofluorocarbon (CCl3F), were given the nicknames CFC-12 and CFC-11, respectively, so that they could be remembered more easily. Chemically, CFCs are a part of a group of compounds called halocarbons (carbon- and halogen-containing compounds).

What is the equation for formation of ozone?

O2 + ℎν(<242 nm) → 2 O. Each oxygen atom then quickly combines with an oxygen molecule to form an ozone molecule: O + O2 → O. The ozone–oxygen cycle: the ozone molecules formed by the reaction above absorb radiation having an appropriate wavelength between UV-C and UV-B.

What is ozone layer depletion reaction?

The term ozone depletion means that the destruction of O3 exceeds the creation of O3. When present together in the stratosphere, chlorine (Cl) and ozone quickly react to produce chlorine oxide. Bromine can also act as a catalyst to destroy stratospheric ozone.

What are the reactions that cause ozone depletion?

The most reactive of these gases are chlorine monoxide (ClO), bro- mine monoxide (BrO), and chlorine and bromine atoms (Cl and Br). These gases participate in three principal reaction cycles that destroy ozone.

What is the other name of CFC?

chlorofluorocarbon (CFC), any of several organic compounds composed of carbon, fluorine, and chlorine. When CFCs also contain hydrogen in place of one or more chlorines, they are called hydrochlorofluorocarbons, or HCFCs. CFCs are also called Freons, a trademark of the E.I.

What are CFCs class 10th?

Chlorofluorocarbons (CFC) are gases used for various purposes including solvents, refrigerants and aerosol sprays. They are organic chemicals and contain carbon, (sometimes hydrogen,) chlorine, and fluorine.

How do chlorofluorocarbons contribute to ozone depletion?

Gaseous CFCs can deplete the ozone layer when they slowly rise into the stratosphere, are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules. See Ozone Depleting Substance.)

How ozone layer is formed in our atmosphere write chemical equation What is the importance of ozone layer?

Ozone, with the chemical formula O3, forms from ordinary oxygen in the upper stratosphere with the energy from the sun’s ultraviolet rays. Ozone also forms in the lower atmosphere from natural and industrial processes.

Who discovered CFC?

Sherwood Rowland and Mario J. Molina discovered that chlorofluorocarbons (CFCs) could deplete Earth’s atmospheric ozone layer, which blocks the sun’s damaging ultraviolet rays. When the scientists reported their findings in 1974, CFCs were widely used as refrigerant gases and as propellants in aerosol sprays.
