At STP, one mole of oxygen and one mole of neon contain equal numbers of A) atoms but the neon has a greater mass. B) atoms but the oxygen has a greater mass. C) particles but the neon has a greater mass. D) particles but the oxygen has a greater mass.

dynamic equilibrium is the answer.

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 :

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
