Calculate either [h3o ] or [oh–] for the solutions below at 25 c. [oh-]=1.83x10^-7 m [h3o+]=? m

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
