The chemical formula for sucrose (table sugar) is C12H22O11. The density of sucrose is 1.59g/cm3. The side of a perfect cube of sucrose is 1.20 cm. The mass of sucrose in this cube is , and the amount of moles of sucrose in this cube 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 :

it takes on an electronical energy
