8. One reaction that can be used to remove NO gas from power plant emission is its reaction with methane. CH4(g)-4N0(g) → 2N2(g) + CO2(g)-H20(g) If NO is being removed at a rate of 1.18 x 10-2 mo1 L-1 s-1, at what rate is Co2 gas being formed? Answer:
a flare is fired from the deck of a sinking ship. Its trajectory can be modelled by the function h(t) = -4.9t^2 + 92t where h is the height of the flare in meters and t is the time in seconds. A seagull is flying 100m above the sinking ship. How long will the flare be above the bird if it continues to fly at the same height?
Alternative Exercise 3.119 A pistol that fires a signal flare gives the flare an initial speed (muzzle speed) of 104 m/s Part A If the flare is fired at an angle of 61.0°aboe the horizontal on the level salt flats of Utah, what is its horizontal range? You can ignore air resistance. ANSWER km Part B If the flare is fired at the same angle over the flat Sea of Tranquility on the moon, where g-1.6m/s', what is its horizontal...

19. Carbon dioxide emission from gasoline used in vehicles generates a negative externality. How many of the following policies could potentially reduce the negative externality problem? Increases in gasoline taxes Replacing existing roads with toll roads Subsidies for low-emission or high gas mileage vehicles a) 1 b) 2 c) 3 d) None of these policies could reduce the negative externality problem
In project estimation we need to calculate for example PRED(0.20) . how to find this value PRED(0.20) = 0.80 ?

Please help me how to calculate rate constant k
dt The rate of a gas-phase reaction occurring at 400K is reported in the literature in the form ap4 = 3.66 pź atm h' The equation is to be re-written in the more usual form -1A = kca² kmol m 5+ Calculate the value (with units) of the rate constant k. [0.0334 mồ kmol's']
How will the estimation of distance from the reference point on the river bank to the water edge affect depth profiling measurements?
A monatomic gas exhibits two electronic transitions from the ground state by absorption of visible light as revealed by the UV-VIS absorption spectrum of this gas shown below. Illustrate these absorption processes on the energy level diagram template provided below. Make sure to include the wavelength of light corresponding to each transition on your illustration. 400nm 600nm n=3 n=2 Wavelength (A) Emission is observed to occur from the monatomic gas for the transition from the n-3> level. Calculate the energy...
