Reactions with nonmetal oxides

Reaction with Nonmetals. Bromine oxidizes sulfur and a number of its compounds. 

Ignition on contact with bromine pentafluoride (or violent reaction), chlorine trifluoride, fluorine, metals (powdered) + water, aluminum-titanium alloys + heat, metal acetylides (e.g., cesium acetylide, copper(I) acetylide, lithium acetylide, mbidium acetylide), nonmetals (e.g., boron ignites at 700°C), phosphoms, sodium phosphinate. Violent reaction with acetaldehyde, aluminum + diethyl ether, dipropylmercury, titanium (above 113°C). Incandescent reaction with cesium oxide...

Another common kind of reaction of oxides is the combination of metal oxides (basic anhydrides) with nonmetal oxides (acid anhydrides), with no change in oxidation states, to form salts. 

Like oxygen, sulfur gains two electrons and forms the sulfide ion (S ) when it reacts with metals or with hydrogen. But in its reactions with nonmetals, sulfur can have other oxidation numbers. Much of the sulfur produced in the United States is taken from deposits of elemental sulfur by the Frasch process, shown in Figure 8.8. 

B. Reactions of Metals with Nonmetals (Oxidation-Reduction)... 

Reactions of Nonmetal Oxides with Water. Nonmetal oxides are called add anhydrides (or... 

Reactions of Metal Oxides with Nonmetal Oxides. Another common kind of reaction of weak adds will appear in chapter 6. 

This type of reaction occurs when rainwater reacts with nonmetal oxide pollutants in the air to form what has been commonly referred to as acid rain. Acid rain has been a troublesome phenomenon in regions surrounding heavily industrialized areas. Vegetation can be killed metal and granite statues are corroded and the health of people can be adversely affected by acid rain. 

Phosphoms shows a range of oxidation states from —3 to +5 by virtue of its electronic configuration. Elemental P is oxidized easily by nonmetals such as oxygen, sulfur, and halides to form compounds such as 2 5 2 5 reduced upon reaction with metals to generate phosphides. The... 

Many nonmetal oxides are acidic in the sense that they react with water to form acids. Looking at the reaction... 

Many nonmetal oxides are Lewis acids that react with water to give Bronsted acids. An example is the reaction of C02 with water ... 

A typical reaction of the nonmetal halides is their reaction with water to give oxoacids, without a change in oxidation number ...
