Vinegar is classified as a mixture. What does this tell you about vinegar? 1Vinegar is made of atoms of one type of element
2Vinegar has a composition that is the same wherever it is found
3Vinegar has two or mores pure substances that can be physically separated
4Vinegar is made of atoms of different elements chemically bonded together

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 answer is 75.0%.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
