The most straightforward way to determine whether a given object is chiral is to draw or visualize the object’s mirror image and see if the two are identical (that is, superimposable). If the object contains an internal plane of symmetry then it must be achiral. What is Superimposable and nonRead More →
Common examples of VOCs that may be present in our daily lives are: benzene, ethylene glycol, formaldehyde, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene. What is included in VOC? VOCs typically are industrial solvents, such as trichloroethylene; fuel oxygenates, such as methyl tert-butyl ether (MTBE); or by-products produced by chlorinationRead More →
Russia is the world’s top methane emitter from oil and gas. Animal agriculture is a similarly large source (30%); primarily because of enteric fermentation by ruminant livestock such as cattle and sheep. What is the largest environmental source of methane? The largest source of anthropogenic methane emissions is agriculture, responsibleRead More →
Methane is emitted from a variety of anthropogenic (human-influenced) and natural sources. Anthropogenic emission sources include landfills, oil and natural gas systems, agricultural activities, coal mining, stationary and mobile combustion, wastewater treatment, and certain industrial processes. How is methane formed in natural gas? As the organic matter moves deeper intoRead More →
Methane is lighter than air, colourless and, despite what you might think considering animals burp it out, odourless. … Chemically, methane is a compound made up of one atom of carbon and four atoms of hydrogen (CH4). It is the main component of natural gas. Why is methane lighter thanRead More →
On Titan, the clouds and rain are formed of liquid methane. On Earth, methane is a flammable gas, but Titan has no oxygen in its atmosphere that could support combustion. Also, the temperatures on Titan are so cold — minus 300 degrees Fahrenheit (minus 149 degrees Celsius) — that theRead More →
What is the percentage of methane in the biogas? Explanation: Anaerobic processes could either occur naturally or in a controlled environment such as a biogas plant. Depending on the waste feedstock and the system design, biogas is typically 55 to 75 percent pure methane. 6. How do you calculate percentageRead More →
