24.063/8.021 = 3 half lives
(1/2)^3 =1/8
Answer: 387 kJ energy is released
Explanation:
Endothermic reactions: These are the reactions in which energy is required in the reaction. The energy of the products are more than the energy of the reactants.
is positive.
Exothermic reactions: These are the reactions in which energy is released in the reaction. The energy of the products is less than the energy of the reactants.
is negative.
The given balanced equation is ;
![\Delta H=-484kJ](https://tex.z-dn.net/?f=%5CDelta%20H%3D-484kJ)
According to stoichioetry :
2 moles of hydrogen reacts to give = 484 kJ of heat
Thus 1.60 moles of hydrogen reacts to give =![\frac{484}{2}\times 1.60=387kJ](https://tex.z-dn.net/?f=%5Cfrac%7B484%7D%7B2%7D%5Ctimes%201.60%3D387kJ)
Thus 387 kJ energy is released
Ozone is not classified as particulate.
A particulate is a very small solid particle that can exist in suspension in both liquid and a gas. This particle remains suspended because it does not dissolve in the liquid or gas that it is suspended in. Dust and ash are capable of being particulates in both gases and liquids. Lead has been known to be a particulate in water, acting as a contaminant.
On the other hand, ozone is a gas that exists as a molecule of three oxygen atoms bonded together. For this reason, Ozone can not be particulate. The correct answer is A.Ozone.
