These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or activeshield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals.

What is an example of active packaging?
An example of active packaging = widgets in beer cans release gas when the can is opened to give the beer a 'foamy head'.
What are the products from the reaction of water and an active metal?
The products from the reaction of water and an active metal typically include hydrogen gas and a metal hydroxide. For example, when sodium reacts with water, it forms sodium hydroxide and hydrogen gas.
Is endocytois an example of active or passive transport?
Endocytosis is an example of active transport.
Do all jovian planets have active volcano?
No, not all jovian planets have active volcanoes. For example, Jupiter and Saturn do not have active volcanoes. However, some of the moons that orbit these planets, such as Io (a moon of Jupiter), do have active volcanoes.

What is a infrared active gas?
Absorption of energy from IR radiation can only occur when the wavelength of radiation and the wavelength of the bond vibration match. If a molecule has symmetry...for example no dipole, we say it is IR inactive. CO2 has no dipole....this would be an IR inactive gas...Cl2 as well. A gas that has a dipole would be IR active. Propene would be a nice example of an IR active gas.It possesses a dipole. One would see a signal around 1650.A:CO2 has no permanent dipole. However, when CO2 undergoes a bending vibration, its dipole moment changes from zero to some non-zero value. This vibration produces a change in dipole moment and is therefore IR active.
