4. The Debye-Huckel limiting law is strictly valid only in the limit of infinite dilution. A more widely applicable equation is the Debye-Huckel equation: 0.510 z,z_|V7 1+(0.328aT log Y This equation applies at 25 °C in dilute aqueous solution. For a 0.00100 m aqueous solution of CaCl2 at 25 °C, the y is found experimentally to equal 0.888. Use this to determine the value of the constant a (which is related to the ion size and has units of A)....

answer please number 1) a and b and 2 and 3
Experiment 4: Limiting reagent Often reactants are added in amounts different from the proportions given by the chemical equation in such cases, only one of the reactants may be completely consumed at the end of the reaction, whereas some amounts of other reactants will remain unreacted. The limiting reactant (or limiting reagent) is the reactant that is entirely consumed or converted to product when a reaction goes to completion....
