So your question ask to complete the table in your problem using the law of constant composition and the table summarize the amount of iron and chlorine produced upon the decomposition of the sample iron and the data that would complete the table is FeCi3(162.2), Fe(0.508), Cl(0,967)

Answer : The mass of Fe and Cl in sample B is 3.341 g and 6.371 g respectively.

Explanation :

Law of definite proportion : It is defined as a given compound always contains exactly the same proportion of elements by weight.

The balanced chemical reaction will be,

2FeCl_3\rightarrow 2Fe+3Cl_2

First we have to calculate the ratio of mass of FeCl_3.

\text{Ratio}=\frac{\text{Mass of }FeCl_3 \text{in sample A}}{\text{Mass of }FeCl_3 \text{in sample B}}

\text{Ratio}=\frac{3.785g}{1.475g}=2.566

Now we have to calculate the mass of Fe and Cl in sample B.

\text{Mass of Cl in sample B}=2.566\times \text{Mass of Cl in sample A}

\text{Mass of Cl in sample B}=2.566\times 2.483g=6.371g

and,

\text{Mass of Fe  in sample B}=2.566\times \text{Mass of Fe in sample A}

\text{Mass of Fe in sample B}=2.566\times 1.302g=3.341g

Therefore, the mass of Fe and Cl in sample B is 3.341 g and 6.371 g respectively.

<h3>The enthalpy of the reaction : C.226.73 kJ</h3><h3>Further explanation</h3>

Delta H reaction (ΔH) is the amount of heat change between the system and its environment

(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)

The change in enthalpy in the formation of 1 mole of the elements is called enthalpy of formation

Delta H reaction (ΔH) is the difference between product enthalpy and reactant enthalpy (Hp-Hr)

Reaction :

2C + H2 -> C2H2

(ΔH) reaction = (ΔH) product - (ΔH) reactants

(ΔH) reaction = (ΔH) C2H2 - ((ΔH) C + (ΔH) H2)

for free element (ΔH) it has zero value, so (ΔH) C and (ΔH) H2 have zero value

From the available data: Hf (kJ / mol) C2 H2 (g)=  226.73

then

(ΔH) reaction = ΔH) C2H2 - ((ΔH) C + (ΔH) H2)

(ΔH) reaction = 226.73 - (0 + 0)

(ΔH) reaction = 226.73 (answer C)
