The phophorus pentoxide used to produce phosphoric acid for cola soft drinks is prepared by nurning phosphorus in oxygen.
(a)what is the limiting reactant when 0.200 mol of p4 and and 0.200 mol of o2 react according to p4 + 5o2 ? p4o10
(b)calculate the percent yield if 10.0 g of p4o10 is isolated from the reaction.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
