It's been estimated the the oil and gas industry emitted 81,525 kilotons of methane from all sources in 2019. How many kilotons of carbon is this?
The atomic mass of carbon is 12.011 and the atomic mass of hydrogen is 1.008. 1 kton = 1000 ton. 1
ton = 1000 kg. 1 kg = 1000 g.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
