Indicator paper can be used to measure the of a solution. indicators are substances that are different depending on the ph of the solution tested. another way to measure the acidity of the solution is the , which uses electrodes placed in solution to directly read the results.

sorry, but im just learning some chemistry myself so i only know that the 1st blank is: Ph

hope you can find what the other 2 blanks are

a graduated cylinder.

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 :
