You may get a 404 error for images because you have Hot Link Protection turned on and the domain is not on the list of authorized domains. If so how? Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. It was observed that DMO hydrolysis involved two reactions in series, with monomethyl oxalate (MMO) as an intermediate product. There are two types of weak bases, those as modeled by ammonia and amines, which grab a proton from water, and the conjugate bases of weak acids, which are ions, and grab the proton to form the weak acid. Question Enter chemical equations and identify corresponding equilibrium It occurs naturally in many plants. close.
