Zinc fluoride (znf2) dissociates according to the following equation: znf2(s) ⇌ zn2+(aq) + 2f–(aq) ksp of this equilibrium is 3.0 × 10–2. if the concentration of zinc ions (zn2+) in a solution is measured to be 4.4 × 10–1 m, what is the concentration of the fluoride ions (f–)?

An engineer decides to use a slightly weaker material rather than a stronger material, since she knows that the stronger material can break suddenly. this is an example of what? a choosing a material that will show warning before it fails b using composite materials that combine strength c using a material for multiple applications d using design techniques that increase efficiency and reduce cost
