The balanced reaction is :

$3Cl_{2}(g)+2FeI_{3}(aq)\rightarrow 2FeCl_{3}(aq)+3I_{2}$

Iodine produce = 20.92 grams

Ferric Chloride produced = 8.92 grams

Explanation:

Molar mass : The amount of sustance present in 1 mole of it.

1 mole = Molar mass of the substance.

1 mole of Cl2 = 71 gram

3 mole of Cl2 = 71 x 3 = 213 gram

1 mole of I2 = 253.8 gram

3 mole of I2 = 3 x 253.8 = 761.4 gram

1 mole of FeCl3 = 162.2 gram

2 mole of FeCl3 = 2 x 162.2 = 324.4 gram

1 mole of FeI3 = 436.56 gram

2 mole of FeI3 = 2 x 436.56 gram =873.12

(use periodic table for calculation)

According to the given question 12 gram of Cl2 reacts with 24 gram of FeI3

The balanced equation is :

$3Cl_{2}(g)+2FeI_{3}(aq)\rightarrow 2FeCl_{3}(aq)+3I_{2}$

Here

$Cl_{2} =chlorine$

$FeI_{3}=ferric\ Iodide$

FeCl3= ferric Chlorie

$I_{2}= Iodine$

This shows:

3 mole Cl2 = 2 mole FeI3 = 2 mole FeCl3 = 3 mole I2

first ,calculate the limiting reagent (the substance present in less quantity)

3 mole Cl2 = 2 mole FeI3

213 gram of Cl2 = 873.12 gram of FeI3

1 gram =

$\frac{873.12}{213}$

12 gram of Cl2 will give =

$\frac{873.12}{213}\times 12$

= 49.18 gram of FeI3 is needed

FeI3 present = 25 gram

So, FeI3 is limiting reagent as it is less than needed

Now , Find the amount of Products with 24 gram of FeI3 because it is the limiting reagent

1. To calculate FeCL3 produced

2 mole FeI3 = 2 mole FeCl3

873.12 gram of FeI3 = 324.4 gram of FeCl3

1 gram =

$\frac{324.4}{873.12}$

24 g FeI3 =

$\frac{324.4}{873.12}\times 24$ of FeCl3

= 8.92 gram of FeCl3

2. To calculate I2

2 mole of FeI3 = 3 mole I2

873.12 gram of FeI3 = 761.4 gram of I2

24 gram of FeI3

$\frac{761.4}{873.12}\times 24$

= 20.92 gram of I2

Answer from: Quest

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
