On January 1, 2019, Wilkins Company purchased a delivery truck that cost $20,000. $10,000 was paid at the time of purchase and the balance of $10,000 was payable on January 1, 2021. The truck has an estimated useful life of four years and $4,000 salvage value. Straight-line depreciation expense on the truck for 2019 would be

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 :
