Food scientists apply principles of titrations to food testing and develop foods that meet certain food-safety standards. for example, the acidity of milk increases with time, making it sour. which statements make sense? check all that apply.

the options are:

The pH of sour milk is less than 7.

To determine the concentration of the lactic acid in sour milk, you could titrate with a base.

The more sour the milk is, the more base that will be needed to neutralize it.

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 :
