A science teacher states if two ice skaters with approximately the same mass push against one another with the same force, they will move away from one another at the
same speed and same distance. What scientific evidence supports the teacher as correct?

trigonal pyramidal

tetrahedral

trigonal planar

bent

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 :
