First, you're given the simple chemistry equation D=M/V, and you're asked to convert units, metric and imperial, as examples. Then, you're taught the "equation" that is the balanced chemical reaction, and asked to convert units -- grams of reagent, to moles, so you can use the bal...
After the reaction is completed the excess amount of dichromate is measured by titration with ferrous ammonium sulfate. COD is expressed in milligrams per liter (mg/L), which indicates the mass of oxygen consumed per liter of solution. Older references may express the units as parts per million...

This parameter requires detailed information on the FCM in which the chemical is used, as well as what kinds of foods the FCM will come in contact with (e.g., aqueous, fatty, etc.). Further, information on the filling and storage conditions (temperature, time) are necessary. Once ...
In 1976, the United States was second in the world with 48 million metric tons of coke, i.e. 14.4% of the world production. By 1990, the US produced 24 million metric tons, falling to fourth in the world. A gradual decline in production has continued; production has decreased from 20...
Non-metric Multidimensional Scaling (NMDS) was also used to evaluate community variation in nonlinear data, with Kruskal’s stress value used as an indicator of goodness-of-fit (Bennett et al., 2008). The interactions between soil chemical properties and microbial communities were analyzed using ...
