Synthetic oil and synthetic gas : A mixture of hydrocarbons derived by upgrading (i.e., chemically altering) natural bitumen from oil sands, kerogen from oil shales, or processing of other substances such as natural gas or coal. Synthetic oil may contain sulfur or other non-hydrocarbon compounds and has many similarities to crude oil.

Whenever a gas is collected over water, the result is a mixture of the collected gas and water vapor. According to Dalton’s law of Partial Pressures the vapor pressure of the water can be subtracted from the total pressure to give the pressure of just hydrogen gas present in the mixture.

Synthesis and Hydrogen Storage Properties of Be12(OH)12(1

The first crystalline beryllium-based metal−organic framework has been synthesized and found to exhibit an exceptional surface area useful for hydrogen storage. Reaction of 1,3,5-benzenetribenzoic acid (H3BTB) and beryllium nitrate in a mixture of DMSO, DMF, and water at 130 °C for 10 days affords the solvated form of Be12(OH)12(1,3,5-benzenetribenzoate)4 (1).

Main-Group and Transition-Element IRMOF Homologues

A simple two-component procedure was developed to synthesize not only classical zinc-based IRMOFs represented by MOF-5 but also the cobalt and beryllium homologues of this most prominent MOF. The procedure is the first manifestation of mirroring the IRMOF series with other metal centers taken from main-group as well as transition-metal elements.

Calcium hydroxide - Wikipedia

Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca() 2.It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed, or slaked with water.It has many names including hydrated lime, caustic lime, builders'' lime, slack lime, cal, or pickling lime.Calcium hydroxide is used in many appliions, including

Lab 9 - Titrations - WebAssign

The most common type of titration is the acid-base titration. In this experiment, you will determine the concentration of acetic acid, HC 2 H 3 O 2 in commercial vinegar. Vinegar is a mixture of acetic acid and water. In this titration, aqueous NaOH is the titrant, and vinegar is the analyte.

How does sodium hypochlorite react with hydrochloric acid

Sodium hypochlorite is a chemical compound with the formula NaClO and it is composed of a sodium ion (Na+) and a hypochlorite anion (ClO−). It may also be thought of as the sodium salt of hypochlorous acid. When dissolved in water it is commonl

How Do I Determine CO2 Levels by Using Titration

A titration involves the gradual addition of a titrant solution to a solution known as an analyte. The titrant in a titration has a known concentration, whereas the analyte has an unknown concentration of some compound. In order to determine carbon dioxide levels in a solution, you can titrate it with sodium
