<u>Answer:</u> The standard enthalpy change of the reaction is -1076.82kJ
<u>Explanation:</u>
Enthalpy change is defined as the difference in enthalpies of all the product and the reactants each multiplied with their respective number of moles. It is represented as 
The equation used to calculate enthalpy change is of a reaction is:
![\Delta H^o_{rxn}=\sum [n\times \Delta H^o_f(product)]-\sum [n\times \Delta H^o_f(reactant)]](https://tex.z-dn.net/?f=%5CDelta%20H%5Eo_%7Brxn%7D%3D%5Csum%20%5Bn%5Ctimes%20%5CDelta%20H%5Eo_f%28product%29%5D-%5Csum%20%5Bn%5Ctimes%20%5CDelta%20H%5Eo_f%28reactant%29%5D)
For the given chemical reaction:
The equation for the enthalpy change of the above reaction is:
![\Delta H^o_{rxn}=[(1\times \Delta H^o_f_{(CO_2)})+(2\times \Delta H^o_f_{(SO_2)})]-[(1\times \Delta H^o_f_{(CS_2)})+(3\times \Delta H^o_f_{(O_2)})]](https://tex.z-dn.net/?f=%5CDelta%20H%5Eo_%7Brxn%7D%3D%5B%281%5Ctimes%20%5CDelta%20H%5Eo_f_%7B%28CO_2%29%7D%29%2B%282%5Ctimes%20%5CDelta%20H%5Eo_f_%7B%28SO_2%29%7D%29%5D-%5B%281%5Ctimes%20%5CDelta%20H%5Eo_f_%7B%28CS_2%29%7D%29%2B%283%5Ctimes%20%5CDelta%20H%5Eo_f_%7B%28O_2%29%7D%29%5D)
We are given:
Putting values in above equation, we get:
![\Delta H^o_{rxn}=[(1\times (-393.52))+(2\times (-296.8))]-[(1\times (89.70))+(3\times (0)]\\\\\Delta H^o_{rxn}=-1076.82kJ](https://tex.z-dn.net/?f=%5CDelta%20H%5Eo_%7Brxn%7D%3D%5B%281%5Ctimes%20%28-393.52%29%29%2B%282%5Ctimes%20%28-296.8%29%29%5D-%5B%281%5Ctimes%20%2889.70%29%29%2B%283%5Ctimes%20%280%29%5D%5C%5C%5C%5C%5CDelta%20H%5Eo_%7Brxn%7D%3D-1076.82kJ)
Hence, the standard enthalpy change of the reaction is -1076.82kJ
The atomic number is 9 Ions have the same atomic number since atomic number signifies number of protons not electrons
Answer: The correct answer is option d.
Explanation: Energy stored into gasoline is converted into another form of energy. This was very well explained on the basis of Law of conservation of energy. This law states that energy is conserved in the system which means that energy is converted from one form to another form.
The energy stored into gasoline is converted into mechanical energy which helps the car to move and some of the energy is lost in the form of heat.
Hence, the correct answer is Option d.
A. True
The reaction rate depends on the rate constant for the given set of reaction conditions and the concentration
The noble gas configuration means that the electronic configuration for Lithium is written in shortcut by starting with the symbol for the nearest noble gas. Note that the noble gas should be lighter than the said element. In here, the nearest noble gas to Lithium is Helium (He). Then, add the additional electrons. Thus, the noble gas configuration would be: <em>[He]2s¹.</em>
