End products of complete combustion are always carbon dioxide (CO2) and water (H2O). However incomplete combustion may lead to carbon monoxide (CO). Also this is true for 100% pure fuel which is not the case since every hydrocarbon has got some impurity which also shows itself in final products.

Answer / lafangey

along with poisonous gases,water also forms.....coz any fuel(hyrdrocarbon) has H in its molecules so it reacts with O2 and form water.

Carbon di oxide is major compound exhausted but some other
like carbon mono oxide and even small particales if present
in fuel may tends to suspended in air.The other major
compounds are nitrogen sulfur but all these creates the
pollution so now a days many precautions at=re taken into
account before manufacturing these types of fuels and well
pre treated before the final separation.

Are there any methods of preventing cracking of carbon steel welds in refining environments?

Question 86 - (a) Male with genotype GGmm and phenotype gray wingless mates with female with genotype ggMM and phenotype black winged in fruit flies. G is dominant to g in color. M is dominant to m in wing shape. If the actual distribution of the second generation of the fruit flies was as follow : 890 gray wingless, 900 black winged, 115 gray winged, 95 black wingless, calculate the recombination frequency betwen the two genes and distance in recombination units. Let 1 map unit = 1 % recombination. (b) A DNA molecule has 180 base pairs and 20 % adenine. How many cytosine nucleotides are present in this molecule of DNA?

Question 61 – A biochemical trolley of mass 15 kg is towing a trailer of mass 5 kg along a straight horizontal pathway. The trailer and the trolley are connected by a light inextensible tow-bar. The engine of the trolley exerts a driving force of magnitude 100 N. The trailer and the trolley experience resistances of magnitude 10 N and 30 N respectively. (a) Form 2 equations with unknowns T and a, that represents the equilibrium for the 2 systems of the trolley and trailer. (b) Solve the simultaneous equations from the 2 equations that are obtained in part (a) of this question. T is the tension of the tow-bar and a is the acceleration.

Question 108 - (a) The correct statement about both the average value of position (<x>) and momentum (<p>) of a 1-dimensional harmonic oscillator wavefunction is <x> = <p> = 1 - x. Find the value of x. (b) The probabilities of finding a particle around points A, B and C in the wavefunction y = f(x) are P(A), P(B) and P(C) respectively. Coordinates are A (3,5), B (4,-10) and C (6,7). Arrange P(A), P(B) and P(C) in term of a < b < c, when | y-coordinate | signifies the probability.
