Plss help :( A student is asked to measure out 25.0 mL of water. Which of the following pieces of lab equipment should the student use to measure out the water: a 100 mL beaker, a 100 mL volumetric flask, or a 100 mL graduated cylinder? Explain.

where's the diagram?

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 :
