A reaction is initiated at 30°C by dissolving 0.2M fructose-1-phosphate in an aqueous solution. When the reaction reaches equilibrium the concentration of fructose-1-phosphate is 6.52 x 10-5M.
Stoichiometry limiting reagent: find the reagent in excess. then calculate the mass or volume of the products formed.
Suppose 28.3 g of ClF3(g) and 24.4 g of Li(s) are mixed and allowed to react at atmospheric pressure and 25 C until one of the reactants is used up, producing LiCl(s) and LiF(s). Using the NIST value for the enthalpy of formation of ClF3 (webbook...
