For example, Joss et al. presented a classroom activity for predicting the normal boiling point of organic compounds using multivariate linear regression and artificial neural networks, two typical machine learning algorithms. (21) In turn, Antonelli et al. generated a lab activity for multivariate calibration using partial least-squares regression on the programing language R. (22) These hands-on experiences are a valuable asset for incorporating computational skills via the exposition of new tools to solve relevant problems in chemistry and, by doing so, to promote collaborative work and the democratization of knowledge. (13)Several general courses consisting of one or two sessions have been implemented before, including programming, data visualization, and machine learning, among others topics. As an example, The Carpentries, (23) a project focused on teaching computing skills to researchers, has hosted a number of such courses.

5V Pin / VBUSThe Nano ESP32 is the first board to not feature a 5V pin. It has instead been replaced with VBUS, which is a more accurate description of the pin's capabilities.VBUS provides 5 V whenever powered via USB. If powered via the VIN pin, it is disabled. This means that while powering the board through the VIN pin, you can't get 5 V from the board, and you need to use a logic level shifter or an external 5 V power supply.
It looks like the VBUS will not work if we do not run by USB.

An isotope of any element can be uniquely represented as AZX, where X is the atomic symbol of the element, A is the mass number and Z is the atomic number. The isotope of carbon that has 6 neutrons is therefore 126C. The subscript indicating the atomic number is actually redundant because the atomic symbol already uniquely specifies Z. Consequently, it is more often written as 12C, which is written as “carbon-12,” (14C, would thus be written as “carbon-14.”) Nevertheless, the value of Z is commonly included in the notation for nuclear reaction

The collocation results can be used to correct the sensor data to more closely match thedata from the reference instrument. This correction process helps account for known biasand unknown interferences from weather and other pollutants and is typically done bydeveloping an algorithm.

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

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

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

he above video shows, placing zinc metal into the copper(II) solution results in a spontaneous redox reaction (ΔG<0ΔG<0\Delta G <0), and if we placed the copper metal into the zinc solution no reaction would occur (ΔG>0ΔG>0\Delta G >0). In an electrochemical cell, we allow electrons to be transferred, which will spontaneously occur in the direction of ΔG<0ΔG<0\Delta G <0, and a cell operating in this fashion is called a galvanic or voltaic cell, which can be used to provide energy to do work, like the common "battery" we use in flashlights and electrical devices.

to reduce the number of independent variables to one. This is done by making successive measurements where all reactant concentrations are held constant except for one, with that data showing the rate law as expressed for that reactant, and it can then be solved as a single reactant problem This lesson will start by solving the single reactant rate law.

he left part of Figure 12.7 b shows two isobaric transitions for converting ice to steam. The top transition at 1 atm is above the triple point and so liquid water is stable, while the lower transition is below the triple point and the ice sublimes to steam without ever forming a liquid phase. It is important to understand the relationship of these graphs and the differences. The phase diagram represents the phase that would exist for a system at equilibrium as a function of the pressure and temperature. The ri

macroscopic perspective of classical thermodynamics, and the microscopic description central to statistical mechanics. The classical approach defines entropy in terms of macroscopically measurable physical properties, such as bulk mass, volume, pressure, and temperature. The statistical definition of entropy defines it in terms of the statistics of the motions of the microscopic constituents of a system – modeled at first classically, e.g. Newtonian particles constituting a gas, and later quantum-mechanically (photons, phonons, spins, etc.). The two approaches form a consistent, unified view of the same phenomenon as expressed in the second law of thermodynamics, which has found universal applicability to physical processes.

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.
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.
This annotation is public, and anyone can see it, even without an account at hypothes.is. If we comment to a group, only the members of the group can see it.

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.
