Think of a pool-table set up as a model (analogy) for gas behavior: a. How would you use the pool balls to demonstate the effect of an increase in the temperature of a gas sample? b. How would you use this model to demonstrate the effect of adding more gas molecules to the sample? c. […]
a 23.74 ml volume of .0981 M NaOH was used to titrate 25 mL of a weak monoprotic acid solution to the stoichiometric point. determine the molar concentration of the weak acid solution. Express your answer to the correct number of significant figures.
Select a source of chemistry information from the open web (the topic can be any topic related to chemistry or that of your research topic). Evaluate the source and explain why it is or is not a credible source of information. Use the name of your source as the title of your Discussion post. […]
Research a specific carboydrate that and its importance in biology. Discuss it’s structure, whether it is a monosaccharide, disaccharide, or polysachardide. If it is a monosaccharide, discuss its various isomers including where they are found and their approximate composition (i.e., percentages). If it is a disaccharide or polysaccharide discuss its imporatant linkages as well […]
Be sure to read the follow-up posts to your own posts and reply to any questions or requests for clarification. There is a lot of chemistry going on all around you. If you start to observe a bit more intentionally, you will notice many new discoveries, articles, news stories, and breakthrough research happening everyday. […]
