Jamal’s teacher has asked the class to use this picture to explain how potential energy transforms to kinetic energy when an object begins to move.

D

Explanation:

I’ve had this question before. Since it’s stairs, the potential energy would decrease due to height decrease and it will be transformed to kinetic energy

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 :

put the answers   and i could answer.
