2. Measure the length of a page in centimeters to the nearest tenth of a centimeter with the metric edge of a ruler. Note that nine lines divide the space between each centimeter into 10 millimeters. The page is 27.5 cm long

58

Explanation:

ccause that is how long it is

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 :
