Acetylene gas (C2H2) at 25 ºC, 1 atm enters a reactor operating at steady state and burns completely with 140% theoretical air entering at 400 K, 1 atm. If the products leave the reactor at 1200 K and assuming air has a molar analysis of 21% O2 and 79% N2, determine: a) air fuel ratio on mass basis, b) the mass fractions of products, c) the dew point temperature, d) heat transfer per kmol of fuel.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

particle   p is an electron and particle q is a neutron

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
