Methane is another greenhouse gas. One pound of methane traps 25 times more heat in the atmosphere than a pound of carbon dioxide. Methane is also the main ingredient in natural gas. If methane can be captured from landfills, it can be burned to produce electricity, run vehicles, or heat buildings. Write an equation that represents the combustion of methane. Consider the reactants and products of the reaction, and comment on the benefits/ drawbacks of this proposed use of methane.

Carbon dioxide is a greenhouse gas. Could you please give
another example of a greenhouse gas and provide the chemical
structure and describe the primary source of this gas in the
atmosphere.

Methane, a powerful greenhouse gas, is generated via
the anaerobic decomposition of solid waste in landfills. Collecting
the methane for use as a gaseous fuel rather than allowing it to be
released to the atmosphere provides an alternative to natural gas
as an energy source and has a beneficial effect on the environment.
If a batch of waste with mass M(tonnes) [1 tonne or 1 metric ton =
1000 kg] is deposited in a landfill at t=0, the rate of...

Natural gas is primarily methane, CH4, and is used to heat
homes. A typical home is approximately 2000 ft2 and the ceilings
are 8 ft high. The following data may be helpful: The heat capacity
of air is 1.01 J/g·K and the and the enthalpy of combustion of
methane is -890.8 kJ/mol. Assume that the molecular weight of air
is the same as nitrogen, its major component. How many grams of
methane are required to raise the temperature in the...

Methane gas enters a horizontal pipe with a thin wall of 25 cm diameter at a temperature of 309 C with 4.5 tons of mass flow per hour and exits at 289 C. The pipe is smooth and its length is 10 m and the ambient and environmental temperature is 25 C. Since the smear coefficient of the pipe surface is given as 0.8;
a-) Indoor and outdoor convection coefficients (W / m2K),
b-) Heat loss from the pipe to...

methane gas CH4 enters a steady flow combustion chamber at 25
oC and 1 atm and is burned with 40 percent excess air,
which also enters at 25 oC and 1 atm. After combustion,
the products are allowed to cool to 25 oC. Assume
complete combustion, determine the heat transfer per kmol of
CH4

Big Al’s Gas Company owns several gas stations, and they are
looking to add another. One station they are evaluating is located
at a site that has been leased. The lease currently has 30 years
before expiration (so the last cash flow will occur at t = 30). The
gas station is expected to generate a net cash flow of $65,000 for
30 years starting at the end of the first year. If Big Al needs to
invest $500,000 in...
