1) An astronaut travels from Earth to Mars, where the gravitational field strength near the surface is 2 N/kg. The mass of the astronaut has a mass of 80 kg. take g on Earth= 10 N/kg. now the question: When the astronaut is near the surface on mars, what is his acceleration?

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 :

what does the table look like

its first and third is your answer i did the qustion the fourth isnt right
