–What amount of calcium chloride (in moles/liter) should be added to a 0.02 M solution of neomycin sulfate (1:2 electrolyte) to produce an ionic strength of 0.09.

Calculate the mean ionic activity and the mean ionic activity coefficient for the 0.02 M solution of neomycin sulfate at an ionic strength of 0.09 and a temperature of 25 ◦C. Use both equations. Use both equations and compare the results

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
