    1. In essence the vapor pressure above a liquid represents the partitioning of the particles between two phases, the liquid and the gas, that is, there is a fraction of the particles in each phase. There is an interplay between the enthalpy of vaporization (the higher it is, the more they want to be in the liquid phase) and the kinetic energy. The equation that describes this is the Clausius-Clapeyron, which is an exponential function. Like any exponential function, there are two forms, the exponential form, and the natural log form

    1. structuring or classification of folksonomy is termed folksontology.[28] This branch of ontology deals with the intersection between highly structured taxonomies or hierarchies and loosely structured folksonomy, asking what best features can be taken by both for a system of classification. The strength of flat-tagging schemes is their ability to relate one item to others like it. Folksonomy allows large disparat

    1. 443. InChI OER. R.E. Belford, J. Cuadros, A.P. Cornell, T. Gupta, E.C. Bucholtz

      Abstract: This poster will describe an Open Education Resource, the InChI OER (https://www.inchi-trust.org/oer/), designed to help chemists, educators and students find information on, and applications of, the IUPAC International Chemical Identifier (InChI). InChI is a machine readable semantic identifier based on layered line notation for the representation of chemical structure, which with the InChI key represents a new digital nomenclature enabling a wide variety of 21st century semantic web applications and activities that support the practice of chemistry.

      We will present OER content within the Intercollegiate Cheminformatics section of the LibreTexts hyperlibrary on the use of both InChI and the InChI OER, along with an overview of the working groups of the InChI subcommittee of IUPAC Division VIII; Chemical Nomenclature and Structure Representation.

      Although this poster will cover the InChI line notation and the use of the InChI OER to obtain resources on InChI, our goal is to elicit discussion on the evolution of the practice of an empirical science like chemistry, and the role data science should play in the traditional undergraduate curriculum

    1. he following January, with 99.94 percent officially listed as voting "yes".[94] Napoleon's brother, Lucien, had falsified the returns to show that 3 million people had participated in the plebiscite. The real number was 1.5 million.[93] Political observers at the time assumed the eligible French voting public numbered about 5 million people, so the regime artificially doubled the participation rate to indicate popular enthusiasm for the consulate.[93] In the first few months of the consulate, with war in Europe still raging and internal instability still plaguing the country, Napoleon's grip on power remained very tenuous.[95] In the spring of 1800, Napoleon and his troops crossed the Swiss Alps into Italy, aiming to surprise the Austrian armies that had reoccupied the peninsula when Napoleon was still in Egypt.[f] After a difficult crossing over the Alps, the French army entered the plains of Northern Italy virtually unopposed.[97] While one French army approached from the north, the Austrians were busy with another stationed in Genoa, which was besieged by a substantial force. The fierce resistance of this French army, under André Masséna, gave the northern force some time to carry out their operations with little interference.[98] The Battle of Marengo was Napoleon's first great victory as head of state. After spending several days looking for each other, the two armies collided at the Battle of Marengo on 14 June. General Melas had a numerical advantage, fielding about 30,000 Austrian soldiers while Napoleon commanded 24,000 French troops.[99] The battle began favourably for the Austrians as their initial attack surprised the French and gradually drove them back. Melas stated that he had won the battle and retired to his headquarters around 3 pm, leaving his subordinates in charge of pursuing the French.[100] The French lines never broke during their tactical retreat. Napoleon constantly rode out among the troops urging them to stand and fight.[101] Late in the afternoon, a full division under Desaix arrived on the

    1. Plot of vapor pressure as a function of temperature for a variety of substances. It should be noted that this is a "bounded function", with the lower end being the melting point, and the upper end being the boiling point of a substance.

      This graph is important as it shows how you can determine trends in a physical property based on the structure of a molecule. Although water is lighter than diethyl ether and ethanol, it has stronger intermolecular forces holding it together and thus has a lower vapor pressure. This results in a higher boiling point.

    1. This is a very valuable resource for finding safety information on chemicals and it is structured so you can instantly find the source of that information

      You need to realize PubChem is a data aggregator that maintains the provenance of the data. And like anything, you have to analyze it. We have an activity where students find what appear to be conflicting safety recommendations, and are then asked to analyze it.

    1. Discussions during the 2019 OLCC were entirely on the hypothes.is web annotation service, which had been integrated into LibreTexts, and was set up to send an email to students and faculty whenever an annotation was created. In future OLCCs, this notification needs to be extended to other types of social media because “email” is often not students’ preferred means for online communication, and these communications need to be across web platforms.

      We are essentially going to use the model that evolved out of the cheminformatics OLCC, using hypothes.is with LibreText. But I expect much more use of external links as students figure how to do code, and use code libraries as they try and set up sensors to Raspberry Pis.

    1. The publication industry owns science In addition to shaping the content of science, researcher evaluation policies focused on publication statistics contribute to what is essentially a publication industry oligopoly that undermines user access to the research that is published. Because of entrenched journal hierarchies, codified by journal impact factor scores, a handful of large corporate publishers have secure positions in owning “must publish” outlets for scientists. For example, the RELX Group—the corporate owner of the publisher Elsevier, the Scopus database (an aspirational competitor to WoS), the prestigious journals Cell and The Lancet, and the publication database ScienceDirect, among other products—boasts in its 2018 annual report that its Scientific, Technical & Medical division organized “the review, editing and dissemination of 18% of the world’s scientific articles.” By its numbers, the group received a whopping 1.8 million article submissions to 2,500 journals, overseen by 20,000 editors and countless peer-reviewers, and in the process reaped $3.3 billion in revenue. Subscriptions constituted 74% of that revenue. To achieve those revenues, the group continues to expand its offerings: Elsevier published 60% more articles in 2018 than a decade prior.

For the 13 elements with standard atomic-weight intervals(hydrogen, lithium, boron, carbon, nitrogen, oxygen, magnesium, silicon, sulfur, chlorine, argon, bromine, and thallium), the standard atomic weight is given as an interval to stress that standard atomic weights are not constants of nature [6]. Each is shown as lower and upper bounds (limits) (Figs. 1.1 and 1.2). Some users of atomic-weight data need a value that is not an interval, such as for purposes of trade and commerce.

      This may also be a place for a talk on the Cheminformatics OLCC, especially if we wish to run another this Fall.

    1. education. The role and scope of lab work especially in the first part of tertiary education has undergone quite some changes. The focus and learning goals and outcomes have become better defined. New technology has been introduced in the lab work. Not only analysing tools and tools for recording results have improved. Tools have been developed to assess students in an easier manner. What tools can be used in chemistry education, what is the role of lab work, how can new technology be used in improving chemistry education

    1. perator is a generalization of the concept of a function applied to a function. Whereas a function is a rule for turning one number into another, an operator is a rule for turning one function into another. For the time-independent Schrödinger Equation, the operator of relevance is the Hamiltonian operator (often just called the Hamiltonian) and is the most ub

    1. This chart shows price changes for goods and services from January 1998 to December 2018

      note how college textbooks are in on this.

    1. Unfortunately the real spectra have been destroyed in the (conventional) publication process. Even so, these tools can carry our information archeology to make reasonable estimates of what the original spectra might have looked like.

    1. reparing the Stretch Image for your microSD card

      I am assuming we could unzip an image of a particular IIAB and then follow the next step to install it on a micro SD card, and then we could run the Raspberry Pi with it, right?

    1. Python Program

      This activity is placed in the Thonny editor, but the text strings are red, not green when I use the CKEditor code snippet for python. Does this make sense, and is it an issue?

      Isn't it amazing how creative and determined people can be, to hook up a battery with 3,000 cells! One beauty of LibreText is you can add stuff that you think would interest people to your text.

    1. Click the down-arrow next to Sort by Occurrence  and choose Sort by Alphanumerical

      When I do this, I get three pages like in figure 3, but there is only one column in each page, not 3. After sorting alphabetically, when I go to the second page, it starts with it starts with further information and ends with mass spectrometry, with the third page starting with solubility.

      This has me thinking that the second and third columns are not showing in the overlay.

    1. To help you find relevant citations we offer 'Smart citation suggestions' which use our SmartSearch algorithm to automatically suggest relevant references. To use this feature, place your mouse cursor where you want to insert the citation then click Smart citation suggestions.

      Smart Citations are amazing. I am curious if Hdot works on this as it has to be activated.

      I think this needs editing

    2. Substance and Reaction Records, and these enable substances/reactions to be searched precisely in association with words/topics

      I understand what is being said here, but is this also why you can combine text and structure search? (I realize that is a different thing, but you had said SciFinder was not set up that way, and so I am wondering)

    1. dictionaries and hierarchies

      T11 I am assuming dictionaries are Compendex and Reaxys Index terms. Are there others, and what do we mean by hierarchies. Taxonomies?

    2. Let’s now go back to the initial list of options(Fig.2.2

      What is the shortcut for doing this. I can't find a breadcrumb or trail, and the back arrow does not go there. I can click Quick search, and redo the search, but there must be a better way.

    3. AND –although terms entered without any operator are interpreted as AND

      How close do the words need to be? I assume in the same document, or "record", if this is done in substance or reaction records.

    4. Summary

      I am thinking that this document should be covered first, before the structure search document. At least some aspects of this would have been useful to have covered prior to the first document (File 5)

    5. nd/orprepositions

      I am not sure what you mean by this. In the next statement you say OR, but here you say "and/or".

    6. may

      are we editing this for "American" English? I would think "can" instead of "may" is better

    7. eaxys uses severalhundred algorithms to interpret the queryand directly gives answers that may be in Document, Substanceand/or ReactionRecords

      Is there a place where further documentation on this can be found. I have Thibault's article from the ACS symposium series book, and will look this up there.

    1. and we may want to review all reactions regardless of whether yields are quoted.

      So if a yield is not reported, the planner will not show it unless you set this to zero % yield, right?
