PPT-Stoichiometry of Precipitation Reactions

1 Identify the species present in the combined solution and determine what reaction occurs  2 Write the balanced net ionic equation for the reaction  3 Calculate the moles of reactants  4 Determine which reactant is limiting. Made famous by S. Ohno, who suggested WGD can be a route to. . evolutionary innovation (focusing on . neofunctionalization. ). Ohno proposed in the 1970s that vertebrate lineage underwent two WGDs .
