Barium oxide BaO

Triethylamine was purchased from Fisher Scientific Company and distilled from barium oxide (BaO) immediately before use and added to the reaction mixture via syringe. 

The only exception is barium which, in excess oxygen, forms a mixture of barium oxide, BaO, and barium peroxide, Ba02. 

It is produced by the reduction of barium oxide (BaO), using aluminum or sihcon in a high-temperature vacuum. It is also commercially produced by the electrolysis of molten barium chloride (BaCy at about 950°C, wherein the barium metal is collected at the cathode and chlorine gas is emitted at the anode. 

The nitrates are considerably endothermic in their decomposition and therefore deliver less heat than chlorates or perchlorates, but they can be used with less fear of accidental ignition. Barium nitrate is often selected for white-light mixtures. The barium oxide (BaO) product formed upon reaction is a good, broad-range molecular emitter in the vapor phase (the boiling point of BaO is ca. 2000°C), and condensed particles of BaO found in the cooler parts of the flame are also good emitters of incandescent light. 

An oxygen-deficient flame is required for a good-quality green flame. Otherwise, barium oxide (BaO) will form and emit a series... 

Self-Test H.1A When aluminum is melted and heated with solid barium oxide, BaO, a vigorous reaction takes place, and elemental molten barium and solid aluminum oxide, A1203, are formed. Write the chemical equation for the reaction. 

Test barium oxide BaO in the same way. Since this oxide reacts vigorously with water to form the hydroxide, Ba(OH)2, we might as well use the hydroxide as a starting point, but should bear in mind that it is essentially the same thing as the oxide BaO. No yellow color appears when titanium sulphate is added.

Barium oxide (BaO). At > 800 °C Ba3WOe is formed 6BaO + W Ba3WOj + 3Ba. Above 1000 °C, the reaction ceases, because the bronze compound dissociates thermally into WO3 and Ba, which evaporates. Above 1400 °C, the tungsten surface is clean. 

A Many starting materials could be used, but barium oxide (BaO) is not a suitable choice. BaO is highly hygroscopic and absorbs carbon dioxide from the air. This means an amount of BaO/Ba(OH) / BaCO would be weighed out rather than the molar quantity of BaO required. The mixture of starting materials would be deficient in barium, and hence, so would the product. In cases like these, where the logical choice is unsuitable, a metal carbonate or nitrate would be used. These metal salts decompose stoichiometrically to the oxide on heating ...

Acidic oxides such as carbon dioxide react with basic oxides like calcium oxide (CaO) and barium oxide (BaO) to form salts (metal carbonates), (a) Write equations representing these two reactions, (b) A student placed a mixture of BaO and CaO of combined mass 4.88 g in a 1.46-L flask containing carbon dioxide gas at 35°C and 746 mmHg. After the reactions were complete, she found that the CO2 pressure had dropped to 252 mmHg. Calculate the percent composition by mass of the mixture.
