Answer: The enthalpy of reaction is, -206.18 kJ
Explanation:-
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The final reaction is
The intermediate balanced chemical reaction will be,
(1)
(2)
(3)
Now adding (2) and (3) and subtracting (1) , we get :
Therefore, the enthalpy of reaction is, -206.18 kJ
Answer:
The use of metal salts. some of the compound produce intense colors when they are burned
This has to be more specific..........but the name of the cell is called a galvanic cell and cations react at the cathode. Hope this helps.
The correct answer is D. Cesium chloride is held together by ionic bonding. This substance is a salt like sodium chloride. It is also soluble in water. When it dissociates, it forms into cesium ions and chloride ions.
40 percent is the best answer and I’m positive it’s right .
