When burned, methane gives off heat at a rate of 342 J/g. How many kilojoules of heat will be given off when 4.50 kg burns? What is the conversion factor from Joules to calories? The average kinetic energy of UF_6(...
However, when fossil fuels are burned, they release greenhouse gases (GHGs) like carbon dioxide (C02), methane (CH4) and nitrous oxide (N20) into the atmosphere. When GHGs build up in the atmosphere, they trap the sun’s radiation and prevent it from being released into space, warming Ear...
What happens when methane is burned? What is the importance of photosynthesis to organisms other than plants? How does the root system in weed seedlings develop? What would happen if our atmosphere consisted of pure oxygen? How does fungi affect plants? How is ocean acidification expected to aff...
How does Hess's law help us determine the enthalpy change of a reaction? Define enthalpy of solution Calculate the enthalpy of combustion (or heat transfer) of 1 kmol of gaseous methane, in kJ. (a) At 25 degrees Celcius, 1 atm with liquid water in the products; (b) At 25 degrees Ce...
(by volume) nitrogen, 21.0% oxygen, 0.9% argon, and 0.03% carbon dioxide. Normally, air is 1–3% water vapor by volume. In addition, air contains a large variety of trace level gases at levels below 0.002%, including neon, helium, methane, krypton, nitrous oxide, hydrogen, xe 水独家...
To make things worse, methane can persist in the atmosphere for up to 100 years or more.Click Here for more information from the EPA about greenhouse gases.Jet Vapor Trails Are Also Warming The PlanetJet aircraft contrails are also playing a role in Global Warming. When combustion byproducts...
Cayuga Lake is one of our community’s most precious natural assets. Not only does it offer a large array of recreational opportunities, but it also provides the drinking water for over 100,000 people. As global warming accelerates and fresh water sources become increasingly scarce, we are fort...
(酶)to speed up the process. The digestion process produces methane, which can be burned to drive machines to produce electricity, or can be purified and fed into the gas network and piped to homes and businesses. British Gas says supplying the gas rather than electricity is far more ...
The big surprise in one new study, conducted by environmental scientists at Stanford University, is the amount of unburned gas that leaks into kitchens when a stove is off. They found that more than three quarters of methane (甲烷) that escapes from a stove does so when it is not in use...
The burning of these fuels produces greenhouse gases, such as carbon dioxide and methane, which heat up the atmosphere and cause global warming. A carbon tax is seen as reducing emissions by making it more expensive to use carbon-based fuels, therefore giving companies a reason to become more...
