What human made chemical damages the ozone layer?
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.
What is an example of cyclic hydrocarbon?
A halogenated hydrocarbon is a hydrocarbon in which one or more hydrogen atoms is replaced with a halogen atom such as chlorine or fluorine. One example of a halogenated hydrocarbon is trichloroethylene.
What chemical reactions do both ethane and ethene undergo?
Both ethane and ethene can undergo combustion reactions to produce carbon dioxide and water. They can also undergo halogenation reactions with halogens such as chlorine or bromine to form halogenated hydrocarbons. Additionally, they can undergo polymerization reactions to form longer chain hydrocarbons or polymers.
What family of hydrocarbons are always saturated compounds?
Alkanes are always saturated hydrocarbons. They contain only single bonds between carbon atoms, making them fully saturated with hydrogen atoms.
Who first proposed a correlation between chlorinated hydrocarbons and ozone depletion?
The correlation between chlorinated hydrocarbons and ozone depletion was first proposed by chemists Rowland and Molina in a paper published in 1974. They showed that chlorofluorocarbons (CFCs) released into the atmosphere could reach the stratosphere where they catalyze the breakdown of ozone molecules.
What element reacts with hydrocarbons to from Teflon and freon?
Fluorine reacts with hydrocarbons to form Teflon (polytetrafluoroethylene) and Freon (chlorofluorocarbons).
How many gases are there in a fire extinguisher?
Co2 is one of them. There are many others, including air, nitrogen and halogenated hydrocarbons.
The types of fire extinguishing agents for aircraft interior fires are?
water, carbon dioxide, dry chemical, and halogenated hydrocarbons.
What has the author W C Elbert written?
W. C Elbert has written: 'Source of halogenated hydrocarbons in an urban water supply' -- subject(s): Municipal water supply, Hydrocarbons
What is the effect of halogenated hydrocarbons to the environment?
CFC's Chlorinated Fluorocarbons) one of the halogenated hydrocarbon subgroups are causing a considerable portion of the break down of the ozone at higher altitudes resulting in more (harmful) ultraviolet radiation from the sun penetrating the atmosphere.
What has the author W F Von Oettingen written?
W F. Von Oettingen has written: 'The halogenated hydrocarbons of industrial and toxicological importance'
Hydrocarbons in which some or all of the hydrogen atoms are replaced by chlorine and fluorine?
Chlorofluorocarbons (CFCs) are hydrocarbons in which some or all of the hydrogen atoms are replaced by chlorine and fluorine. These chemicals were commonly used in refrigerants, propellants, and solvents but are now known to be harmful to the ozone layer.
What human made chemical damages the ozone layer?
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.
What is an example of cyclic hydrocarbon?
A halogenated hydrocarbon is a hydrocarbon in which one or more hydrogen atoms is replaced with a halogen atom such as chlorine or fluorine. One example of a halogenated hydrocarbon is trichloroethylene.
How did the aerosol can change over time?
They use hydrocarbons now; they used to use chlorofluorocarbons (CFC's) which were damaging to the ozone layer.
What pollutant was addressed by the Montreal Protocol?
The Montreal Protocol primarily aimed to address the issue of ozone-depleting substances such as chlorofluorocarbons (CFCs) and halons. These substances were found to contribute to the depletion of the ozone layer in the Earth's stratosphere.
What are the examples of common organic solvents which are classified under the group halogenated hydrocarbons?
Examples of common halogenated hydrocarbons include chloroform, carbon tetrachloride, trichloroethylene, and perchloroethylene. These organic solvents are often used in industries such as dry cleaning, degreasing, and as solvents for chemical reactions. However, they are known to be toxic and pose health and environmental risks, leading to their restricted use in many countries.
