Given the data in the table below, δh°rxn for the reaction ag2o (s) + h2s (g) → ag2s (s) + h2o (l) is kj. substance δh∘f(kj/mol) ag2o (s) -31.0 ag2s (s) -32.6 h2s (g) -20.6 h2o (l) -286

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
