The Ksp of Barium fluoride, BaF2, is 2. The molar mass is Barium fluoride BaF 2 is an inorganic compound with the formula BaF 2. It is a colorless solid that occurs in nature as the rare mineral frankdicksonite. Above ca. Prolonged exposure to moisture degrades transmission in the vacuum UV range.

It is less resistant to water than calcium fluoridebut it is the most resistant of all the optical fluorides to high-energy radiation, though its far ultraviolet transmittance is lower than that of the other fluorides.

It is quite hard, very sensitive to thermal shock and fractures quite easily. Barium fluoride is transparent from the ultraviolet to the infraredfrom — nm to 11— It is used in windows for infrared spectroscopyin particular in the field of fuel oil analysis.

The refractive index is about 1. Barium fluoride is also a common, very fast one of the fastest scintillators for the detection of X-raysgamma rays or other high energy particles. One of its applications is the detection of keV gamma photons in positron emission tomography. It responds also to alpha and beta particles, but, unlike most scintillators, it does not emit ultraviolet light.

Barium fluoride is used as a preopacifying agent and in enamel and glazing frits production.

Its other use is in the production of welding agents an additive to some fluxesa component of coatings for welding rods and in welding powders. It is also used in metallurgyas a molten bath for refining aluminium. Ab initio calculations indicate that contributions from d orbitals in the shell below the valence shell are responsible.

Journal of Applied Physics.The solubility of a substance in water is defined as its ability to dissolve as a solute in the water solvent to form an aqueous solution. For salt compounds this involves dissociation of the salt crystal into solvated cations and anions.

This dissociation is relatively incomplete for many salt compounds, such that an equilibrium is formed of the solid salt and the dissolved ions. For such an equilibrium there is a solubility product constant "Ksp". It is the maximum allowable solubility product of the constituent ion concentrations in a saturated aqueous solution of the salt at a given temperature.

The given compound here is barium fluoride salt. It is a poorly soluble salt in water that will dissolve according to the following solubility equliibrium:. This equation shows that the dissolved ions are formed in a molar ratio.

Therefore the molar solubility "x" of the ions in a saturated aqueous solution of this salt will be:. Try it risk-free for 30 days. Log in. Sign Up. Explore over 4, video courses.

They have a rather average unit cost, and their buildings can be built pretty much everywhere. They have good defense and mobility overall, and can repair both buildings and units. You can find out more about the Terran - and its individual units and tech tree - by visiting Blizzard's official Terran page. Protoss units cost more on average but are extremely powerful.

Any buildings created must be within a certain range of a Pylon, units can be warped into combat, and all structures and units have a shield which regenerates over time.

To learn more about the units and research options for the Protoss, take a look at Blizzard's official page for the race. The Zerg race produce low-cost units in mass quantities and have one production building to manage. Buildings have to be built on a surface called creep, but this provides a speed advantage to friendly units travelling upon it. For an overview of all of the units and tech tree lines available to the Zerg, head over to the official StarCraft 2 site.

There are three important elements to consider in the StarCraft 2 economy: Minerals, Vespene Gas and Supply. Minerals are the most primitive resource, Vespene Gas is used to build advanced units, and your Supply level limits how many units you can field at any given time. When you begin a match, you'll have a patch of minerals to harvest and units to start the harvesting process.

You are encouraged to keep building a number of workers to ensure the harvesting rate increases over time. Note that certain yellow-coloured Mineral fields grant a greater yield, although you shouldn't worry too much about this in your early days. The green Vespene Gas geysers allow you to harvest a second mineral, but each race has to build a specific structure on top of the gas patch first. Get extraction of the gas up and running very quickly in each game, as you'll need it sooner rather than later.

You can increase the Supply value of your base by building certain structures nearby. Should you find yourself unable to build a new unit because you lack Supply, you are considered Supply-capped. You should avoid this situation at all costs.

It is vital that you grow your economy continuously throughout each match, harvest more and more resources, and ensure you have the necessary Supply infrastructure in place at all times. By managing all three of these elements, you hope to use your resources and production in as efficient a manner as possible.Including also the refresh token is optional before your access token expires.

Including it avoids you to be worried about expiration time. You first need to authorize BigML access from your own Google Apps application. After the authorization process you will get your access token and refresh token from the Google Authorization Server.

Then the process is the same as creating a remote source using BigML application described above. You need to POST to the source endpoint an object containing at least the file ID (for Google Drive) or the bucket and the file name (for Google Storage) and the access token, but in this case you will also need to include the app secret and app client from your App.

Again, including the refresh token is optional. Your values for app client and app secret appear as Client secret and Client ID in Google developers console respectively. This way is specially useful if you want to model small amounts of data generated by an application. It can be compressed, gzipped, or zipped. You can also use curl to customize your new source with a name and different parser. For example, to create a new source named "my source", without a header and with "x" as the only missing token.

However, if you do specify it, BigML. While the handling of numeric, categorical, or items fields within a decision tree framework is fairly straightforward, the handling of text fields can be done in a number of different ways.

At the source level, BigML. In the near future, BigML. For text fields, BigML. If all is selected, then both full terms and tokenized terms are used. For example, datasets containing all products bought by users or prescription datasets where each patient is associated to different treatments. These datasets are commonly used for Association Discovery to find relationships between different items.

Once a field has been detected as items, BigML tries to automatically detect which is the best separator for your items. During the source pre-scan BigML tries to determine the data type of each field in your file. For instance, if a field named "date" has been identified as a datetime with format "YYYY-MM-dd", four new fields will be automatically added to the source, namely "date. For each row, these new fields will be filled in automatically by parsing the value of their parent field, "date".

For example, if the latter contains the value "1969-07-14", the autogenerated columns in that row will have the values 1969, 7, 14 and 1 (because that day was Monday). When a field is detected as datetime, BigML tries to determine its format for parsing the values and generate the fields with their components.Version 3 has been released.
