The argument that I am proposing is that Dr. Manhattan is in a constant state of nostalgia. As he experiences all of time at once‚ his past is becoming larger. As his past becomes larger‚ he values all those previous moments more so than his future. Dr. Manhattan values his past over his future so much so that he forces his responses in the present to be a product of his past and not his future. Perhaps a clearer way to say this is to suggest that Dr. Manhattan wants to be himself‚ and not care about

Determining the equilibrium constant from pH values of changing concentrations of ethanoic acid Design Research question: How will altering the concentrations of ethanoic acid affect the pH value‚ and‚ in-turn‚ the equilibrium constant? Background information: When weak acids react‚ the reaction typically does not go to completion. Rather‚ the system goes to an intermediate state in which the rates of the forward and reverse reactions are equal. Such a system is said to be in chemical equilibrium

ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

molecules or solute ions. In pure water‚ a small amount of molecules take part in an equilibrium reaction1. 2 H2O (l) H3O+ (aq) + OH- (aq) This self-ionization of water produces a small amount of both hydronium and hydroxide ions. The equilibrium constant expression for this reaction is called Kw (1.0x10-14)‚ or the ion product of water1. From this number‚ if the concentration of hydronium is known the concentration of hydroxide can be found or vice versa. Strong acids are substances that ionize
