Oxide Nonmetal oxides Britannica

Oxide Oxide Nonmetal oxides: All nonmetals form covalent oxides with oxygen, which react with water to form acids or with bases to form salts. Most nonmetal oxides are acidic and form oxyacids, which in turn yield hydronium ions (H3O+) in aqueous solution. There are two general statements that describe the behaviour of acidic oxides. First, oxides such as sulfur trioxide (SO3) and

Alloying Elements Effects on Properties of Copper Alloys

Unalloyed copper is relatively soft compared to common structural metals. An alloy with tin added to copper is known as bronze; the resulting alloy is stronger and harder than either of the pure metals. The same is true when zinc is added to copper to form alloys known as brass. It should be noted that neither 'brass' nor 'bronze' is a concrete
