The Board had also included manganese dioxide in the list of controlled chemicals.

Several oxides of manganese, for example manganese dioxide, are abundant in nature, and owing to their color, these oxides have been used as pigments since the Stone Age.

The oxidation state 5 can be obtained if manganese dioxide is dissolved in molten sodium nitrite.

Because of the use in glassmaking, manganese dioxide was available to alchemists, the first chemists, and was used for experiments.

Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, by reducing the dioxide with carbon.

The most important manganese ore is pyrolusite (MnO2).

The brown color of ceramic is sometimes based on manganese compounds.

Compared to 1953, levels of manganese in air have dropped.

Before year 2000, more than 1.6 million tonnes have been used of those alloys with a content of 1 manganese, this amount would need 16,000 tonnes of manganese.

Secondly, it was noted that whereas the add on manganese plant in the Australian study had a negative effect on the profitability of the whole project, in the French study, manganese contributed substantially to the project apos s profitability.

Glass for flat glass has a higher magnesium oxide and sodium oxide content than container glass, and a lower silica, calcium oxide, and aluminium oxide content.

Osmium tetroxide (also osmium(VIII) oxide) is the chemical compound with the formula OsO4.

Oxidizers include boron(III) oxide, silicon(IV) oxide, chromium(III) oxide, manganese(IV) oxide, iron(III) oxide, iron(II,III) oxide, copper(II) oxide, and lead(II,IV) oxide.

In biology, manganese(II) ions function as cofactors for a large variety of enzymes with many functions.

Color ranges from yellow to dark brown or black, the latter being due to the presence of manganese.

So it's taking in water and carbon dioxide.

The primary reason for the positive DCFROR was the higher recovery of manganese, using pyrometallurgical processing.

The first set of tables (tables 1 and 2) covers conservativeness factors for sources included in Annex A to the Kyoto Protocol.

Different conservativeness factors are provided for use in adjustments to estimate for a base year and for a year of the commitment period.

And you've got carbon dioxide. I'm gonna do carbon dioxide in orange.

In 2005, a study suggested a possible link between manganese inhalation and central nervous system toxicity in rats.

Now, as we breathe, we produce carbon dioxide, and that carbon dioxide needs to be scrubbed out of the system.

This document compiles and summarizes information relating to national inventories of anthropogenic emissions by sources and removals by sinks of greenhouse gases (GHGs).

The other component on a breathing loop is the carbon dioxide absorbent canister.

You burn it, you release CO2.
