Agaseous fuel containing methane and ethane is burned with excess air. the fuel enters the furnace at 25°c and 1 atm, and the air enters at 200.0°c and 1 atm. the stack gas leaves the furnace at 900.0°c and 1 atm and contains 5.33 mole% co2, 2.09% co, 7.04% o2, 12.16% h2o, and the balance n2. (a) calculate the molar percentages of methane and ethane in the fuel gas and the percentage excess air fed to the reactor. (b) calculate the heat (kj) transferred from the reactor per cubic meter of fuel gas fed. (c) a proposal has been made to lower the feed rate of air to the furnace. state advantages and a drawback of doing so.

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
