What is the mass of the carbon atoms in 433.42 g of propane? What is the molecular formula for butane? What is the molecular weight of sodium bicarbonate? What is the molecular mass of H2O? What are the properties of methane? What is the Lewis structure of methane? What is the molar m...
We know there's methane (甲烷) in the atmosphere, because that's what makes the planet such a pretty blue color. We also know there's hydrogen because of observations made by the Voyager 2 spacecraft when it flew past.But the concentration of other composition, such as water and hydrogen...

Atmospheric methane (CH 4 ) concentrations have more than doubled in the past ~ 250 yr, although the sources of this potent greenhouse gas remain poorly constrained. Freshwaters contribute ~ 20% of natural CH 4 emissions, about half attributed to ebullition. Estimates remain uncertain as ...
What the bubble knows: Lake methane dynamics revealed by sediment gas bubble compositionTo estimate potential sediment CH4 production rates, we incubated sediments from cores taken at 8 m, 20 m and 26 m water depth on the 20 July 2016 and one core at 26 m water depth taken on the 01.03....
produced by anaerobic digestion of biogenic waste in an oxygen-less environment. The difference between biogas and biomethane lies in their composition. Biogas is 45-75% methane, while biomethane is the purified form of biogas with almost 90% methane. Biomethane can be used as a gas substitute....
In a nutshell, gasoline is a mixture of C4 to C12 hydrocarbons specially blended with a few additives to meet the performance needs of automobile engines. That doesn't sound too complicated, but in actuality gasoline is quite complex, consisting of several hundred compounds. The composition ...
This study demonstrates seasonality in the composition of faecal microbiota obtained from hunter-gatherers, which corresponds to the availability of different types of foods, and delineates the difference between this population and the industrialized population.

Methane is a simple hydrocarbon with one carbon atom, highly potent as a greenhouse gas, whereas ethane has two carbon atoms, less potent but significant in natural gas and petrochemical production.
