Explain how you would find the volume of an irregular shaped object?

You can place the object in a graduated cylinder. First measure original volume of water, then measure volume with object in water. Subtract original from new. For example, a 6 gram rock would make a cylinder of water go up 6 tic marks. If the object is large, place it in a tub or pool of water with the volume marked around the edges, like the graduated cylinder. Repeat steps.

Explanation:

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 just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
