Ha and hb are two strong monobasic acids.
25.0cm3 of 6.0 moldm-3 ha is mixed with 45.0 cm of 3.0 moldm-hb.
what is the h*(aq) concentration, in moldm-3, in the resulting solution?
a 1.9. c 4.1
b 2.1. d 4.5

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 :

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
