Q. 7.86 - An Introduction to General, Organic, and Biological Chemistry

Question

If purple spheres represent iodine atoms, white spheres represent hydrogen atoms, and all the molecules are gases

(a) Write the formula for each of the reactants and products.

(b) Write a balanced equation for the reaction.

(c) Indicate the type of reaction as combination, decomposition, single replacement, double replacement.

Step-by-Step Solution

Answer

(a) The Reactants of given reaction is$HI$ and Products are$H_2,I_2$.

(b) The balanced chemical equation is $2HI \to H_2+I_2$
(c) This is a decomposition reaction.

Part (a) Step 1: Given Information

We need to write the reactants and products  of given figure.

Part (a) Step 2: Explanation

We are given that purple sphere represent iodine atoms and white sphere represent hydrogen atoms.

Therefore,

The Reactants of given reaction is $HI$and The Products are $H_2, I_2$.

Part (b) Step 1: Given Information

We need to write the reaction of given molecules.

Part (b) Step 2: Explanation

We have given that reactants of reaction are $HI$ and products are $H_2,I_2$.

Therefore,

The balanced chemical reaction is  $2HI\hspace{0.17em}\to H_2+I_2$.

Part (c) Step 1: Given Information

We need to find the type of reaction.

Part (c) Step 2: Explanation

We are  given reaction is $2HI\hspace{0.17em}\to H_2+I_2$ then we see   One compound is decomposes to two molecules then it is a Decomposition reaction.
