The Haber process for the production of ammonia relies on a heterogeneous catalyst. How does the use of this catalyst affect the yield of the reaction at equilibrium?
Why is (NH4)2CrO4 a molecular compound if ionic is metal + nonmetal and molecular is nonmetal+nonmetal?
An unknown metal hypochlorite salt, M(ClO)2, is subjected to analysis by iodometric titration: the salt is dissolved in dilute sulfuric acid, treated with excess aqueous KI, and then titrated with Na2S2O2 in the same manner as in your experiment
