c. double-walled steel lines and flexible hosesd. none of the answers listed

C. Double-walled steel lines and flexible hoses

Explanation:

The brake units consists of;

Double-walled steel lines carry the brake fluid from the master cylinder along the vehicle frame to flexible hoses attached to wheel cylinders.

the answer would be c

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 :
