A titration involves the addition of a solution of known concentration (titrant) to a known volume of another solution of unknown concentration (analyte). You add the titrant slowly until the reaction is complet
when the acid has been neutralized. At this point, adding more base causes the pH to rise rapidly. After equivalence has been reached, the slope decreases dramatically, and the pH again rises slowly with each addition of the base. The inflection point, which is the point at which the lower...
ifA(x)thenB(x)’. The logic of universal conditionals is underpinned by that ofpropositional conditionals, which take the form ‘ifA(x0)thenB(x0)’, wherex0is a specific object. In mathematics, propositional conditionals are subject to amaterial conditionalinterpretation...
The National Science Foundation funded a 2-year program in the US to investigate the cognitive and mathematics development of children aged 3–6. Interview and assessment data of children’s strategies to solve fair sharing tasks involving fractional quantities are reviewed. Children were asked how ...
50 M HCl calculate pH at HALF- EQUIVALENCE POINT (i.e. when [CH3NH2] = [CH3NH3+] )There are 3 steps to solve this one. Solution Share Step 1 Molarity of of methyl amine (CH3NH2) solution =1.0M Volume of methyl amine ...
The titration's equivalence point is the point at which the titrant concentration is just right to neutralize the solution of the analyte totally. In an acid-base titration, the equivalence point occurs when moles of base equal moles of acid and the sole components of the solution are salt ...
内容摘录Emotions and logic do not have to be enemies. Logic works perfectly in the abstract mathematical world, but life is more complicated than that. Life involves humans, and humans have emotions. Here in this beautiful and messy world of ours we should use emotions to back up logic, ...

To this point in the Day 1 lesson of theShot Put problem based unit, we’ve withheld a significant amount of information with the goal of building anticipation. How did we do it? In this case, we simply shared a video of an athlete throwing a shot put and asked students to jot down...
Further, there is no consensus on the proper way to for- mally capture the notion of motivated reasoning. As a result, even if we agree that a particular empirical pattern could not be generated by Bayesian updating, it is hard to tell whether directional motives are a viable explanation. ...
