Packet 10: Tossup 15

On a Walden plot, higher ionicity is seen in substances named for this property when they are hydrate-based and contain metal chlorides. Adhesion layers remove oxides before a type of wafer bonding named for this property, which is commonly used to combine gold and silicon. (15[1])This property’s “halt” occurs between two points where the slope is zero on a cooling curve. During steel metallurgy, austenite begins cooling after separating from a mixture with this property (15[1])called (15[1])(*) ledeburite. (10[3])Carbon content greater or less than 0.8 percent determines whether steel is “hypo-” or “hyper-[this (10[2])property].” (10[1]-5[2])Biodegradable alternatives to ionic liquids are called “deep (10[1])solvents” (10[2])with this (10[2])property. (10[6])For (10[1])10 points, (10[1])give this term for a binary mixture (10[1])that has a lower melting point than its constituents. ■END■ (10[5]0[3])
