There is no difference between 'gas' and the atmosphere or 'air.' Gas can be chemically homogenous, as purely of one element, or a heterogeneous mixture of many. The atmosphere's air is composed of many gases, but its primary components are nitrogen (N2) and oxygen (O2).
"Air pressure" usually refers to the ambient pressure of the atmosphere around you. "Air pressure" is thus just a special case of "gas pressure". Gas pressure is more commonly measured as the pressure of a gas within a confined space. When the gas is air, it may also be referred to as "air pressure", for example - in tires.
Oxygen has a different valence than fluorine or chlorine. An oxygen atom forms bonds by taking (or sharing) two electrons, whereas fluorine and chlorine, both halogens, each take or share only a single electron, when forming bonds. As a result of this, oxygen can form more complicated types of bonds, since it can bond to two different atoms at once. Fluorine or chlorine can only bond to one atom at a time. There are many other consequences as well. The chemistry of oxygen is quite different from that of the halogens, even though both are nonmetals which acquire electrons when they bond.
A gas is a pure substance, such as carbon dioxide that has enough energy present for its state to change. An aerosol is a mixture, which is a colloidal suspension of particles in a gas.
oxygen is a type of gas and a gas is not a type of anything. plus not all gases let us breathe, only oxygen does. a lot of gases would poison us if we breathed them in.
Cl2(g)+F2(g) --> 2ClF(g)
The answer is Fluorine!Argon, one of the noble gases.
C. Helium is a monoatomic gas at STP.
Iodine, element number 53 is the halogen (Group 17) element in period 5.
Anyone knows when installing chlorine gas detector, sensor how height has to be? Thank you in advance, Pedram
Oxygen is not a fuel for fire; it is the oxidizer. You can substitute a different gas for oxygen such as chlorine, fluorine, or dioxygen difluoride. You can also use solid oxidizers such as potassium nitrate or ammonium perchlorate.
Yes. Explosive when mixed with oxygen or fluorine and even chlorine gas. Hydrogen is flammable. It burns in air or oxygen.
All of the noble gases, hydrogen, nitrogen, oxygen, fluorine, and chlorine.
Fluorine and chlorine are the gases in the fluorine family, at standard temperature and pressure.
Examples: hydrogen, helium, oxygen, fluorine, chlorine, argon, krypton, radon, xenon, neon, nitrogen.
halogens
No, SO2 is an inorganic acid gas made from sulphur and oxygen. A CFC is a chlorofluorocarbon made from fluorine, carbon and chlorine.
There are two gases in fluorine(Halogen) family, which are Fluorine and Chlorine. In some cases bromine can also be included as a gas.
Oxygen
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
yes,they are poisonous.
chlorine is a powerful bonding chemical (Fluorine is the most powerful). Chlorine gas is green and gets in to your lungs and bonds it all up and stops oxygen and causes your lungs to melt. Unpleasant. Common during WWII.
