(a) CO2___Carbon dioxide is colorless. At low concentrations the gas is odorless however, at sufficiently-high concentrations, it has a sharp, acidic odor. At standard temperature and pressure, the density of carbon dioxideis around 1.98 kg/m3, about 1.67 times that of air.
(b) SO2__COLOURLESS GAS OR COMPRESSED LIQUEFIED GAS WITH PUNGENT ODOUR. Colorless gas with acharacteristic, irritating, pungent odor. Colorless gas with a characteristic, irritating, pungent odor. [Note: A liquid below 14°F. Shipped as a liquefied compressed gas.]
(c) O2__Characteristics: Oxygen in its common form (O2) is a colorless, odorless and tasteless diatomic gas. Oxygen is extremely reactive and forms oxides with nearly all other elements except noble gases. ... Ozone (O3), another form (allotrope) of oxygen, occurs naturally in the Earth's upper atmosphere.
(d) H2__At standard temperature and pressure,hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
(b) SO2__COLOURLESS GAS OR COMPRESSED LIQUEFIED GAS WITH PUNGENT ODOUR. Colorless gas with acharacteristic, irritating, pungent odor. Colorless gas with a characteristic, irritating, pungent odor. [Note: A liquid below 14°F. Shipped as a liquefied compressed gas.]
