Hello... I'm doing project about the purity of silicon dioxide from different type of sand
So I need your help to give me more notes and information like theory about the purity of silicon dioxide from river sand and beach sand
*If equivalent conductance at infinite dilution of NaCl, HCl and CH3COONa are 126.45, 426.16 and 91.0 respectively, find the equivalent conductance of acetic acid at infinite dilution.*
The elementary chemical reaction O + CIO >Cl + O2 is made pseudo-first order in oxygen atoms by using a large excess of CIO radicals. The rate constant for the reaction is 3.8 cm^3/molecule s. If the initial concentration of CIO is 1.0 x 10^11 molecules/cm', how long will it take for the oxygen atoms to decrease to 10.% of their initial concentration?
