A gas occupies 1.56 at 1.00 what will be the volume of this gas if the pressure becomes 3.00 atm

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 think it is true since you can test the answer and can use observations to complete it.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
