Answer:
The
of the given reaction is -129.6 kJ
Explanation:
The given chemical reaction is as follows.

Enthalpy of each reactant and products are as follows.




In the given chemical reaction involved two C-H bonds in the reactant side and one C-C bond in the product side therefore, the enthalpy of formation will be the negative.



Therefore, The
of the given reaction is -129.6 kJ

Answer:
110ml
Explanation:
<em>Using the dilution equation, C1V1 = C2V2</em>
<em>Where C1 is the initial concentration of solution</em>
<em>C2 is final concentration of solution</em>
<em>V1 is intital volume of solution</em>
<em>V2 is final volume of solution.</em>
From the question , C1=6M, C2=0.5M, V1=10ml, V2=?



volume of water added = final volume -initial volume
= 120-10
=110ml
The given salts are Barium chloride, lead chloride and zinc chloride.
The balanced chemical reaction between barium chloride and sodium sulfate:

The balanced chemical reaction between lead chloride and sodium sulfate:

The balanced chemical reaction between zinc chloride and sodium sulfate:

Both Barium chloride and lead chloride produce a white precipitate of their respective sulfates upon reaction with sodium sulfate. But BaCl2 is readily soluble in water where as Lead chloride is insoluble in water.
Therefore, the compound is barium chloride.
