Yield strength is defined in engineering as the amount of stress (Yield point) that a material can undergo before moving from elastic deformation into plastic deformation. Yielding - a material deforms permanently The Yield Point is in mild- or medium-carbon steel the stress at which a marked increase in deformation occurs without increase in load. We will use approximately 0.02 mole of each reactant and expect to obtain approximately 0.02 mole of solid product, since the stoichiometric coefficients are all 1 in the balanced equation. You will need to calculate the limiting reactant, and the theoretical yield, from your measured amount of each reactant. For example, if we use 2.00 g CaCl 2Theoretical yield is the yield predicted by stoichiometric calculations, assuming the limiting reactant reacts completely.
