Question

What is one of the products produced when CaCl2 and Fe(NO3)3 react together?

Answer 1

Answer: Option (d) is the correct answer.

Explanation:

The reaction between $CaCl_{2}$ and $Fe(NO_{3})_{3}$ is as follows.

   $CaCl_{2} + Fe(NO_{3})_{3} \rightarrow Ca(NO_{3})_{2} + FeCl_{3}$

Number of reactants are as follows.

• Ca = 1
• Cl = 2
• Fe = 1
• $NO_{3}$ = 6

Number of products are as follows.

• Ca = 1
• Cl = 3
• Fe = 1
• $NO_{3}$ = 2

To balance the equation, on the reactant side multiply $CaCl_{2}$ by 3 and $Fe(NO_{3})_{3}$ by 2. On the product side multiply $Ca(NO_{3})_{2}$ by 3 and $FeCl_{3}$ by 2.

Therefore, the balanced chemical equation will be as follows.

$3CaCl_{2} + 2Fe(NO_{3})_{3} \rightarrow 3Ca(NO_{3})_{2} + 2FeCl_{3}$

Thus, out of the given options, $FeCl_{3}$ is one of the products produced when $CaCl_{2}$ and $Fe(NO_{3})_{3}$ react together.

Answer 2

The answer is FeCI3. I took this on the exam and got it right. :)
