All the following are standard components of the experimental process except
a. models b. controls c. variable d. opinions

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

In the diagram here that represents the reaction, which reactant, a or b, is the limiting reagent?

Amolecule is a(n) - a. element that physically combines with another element. b. particle composed of two or more atoms bonded together covalently. c. element that isn't bonded to another element.
