Germaine wants to know exactly how acidic lemon juice is. which of these can tell him the ph most precisely? a. ph probe b. indicator solution c. red cabbage juice d. ph paper

pH probe

Explanation:

A pH probe is the most accurate and consistent way of measuring pH. While pH paper and an indicator solution is viable, the most precise way would be to use a pH probe or meter

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 :
