Q. 7.97 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify the type of reaction for each of the following as combination, decomposition, single replacement, double replacement, or combustion: ($7.5$)

a. A metal and a nonmetal form an ionic compound.

b. A compound of hydrogen and carbon reacts with oxygen to produce carbon dioxide and water. 

c. Heating calcium carbonate produces calcium oxide and carbon dioxide. 

d. Zinc replaces copper in data-custom-editor="chemistry" $\mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2$.

Step-by-Step Solution

Answer

(a) The type of reaction is the combination 

(a) The type of reaction is combustion

(a) The type of reaction is the decomposition

(a) The type of reaction is singe replacement

Part (a) Step 1: Given information

We need to find the type of the given reaction

Part (a) Step 2: Explanation

We know that

In a reaction in which two or more compounds combine with each other to produce a single compound is called combination reaction

And in the given reaction metal and nonmetal combine with each other to for single compound i.e. ionic compound

Therefore, The given reaction is combination reaction

Part (b) Step 1: Given information

We need to find the type of the given reaction 

Part (b) Step 2: Explanation

As in the given reaction, carbon and hydrogen is reacting with oxygen to produce carbon dioxide and water which is characteristic of a combustion reaction 

Therefore, The given reaction is a combustion reaction

Part (c) Step 1: Given information

We need to find the type of the given reaction 

Part (c) Step 2: Explanation

As in given reaction calcium carbonate heats up to produce two new substances i.e. calcium oxide and carbon dioxide which is characteristic of decomposition reaction.

Therefore, The given reaction is a decomposition reaction. 

Part (d) Step 1: Given information

We need to find the type of the given reaction 

Part (d) Step 2: Explanation

As in the given reaction copper is replaced by the zinc which is characteristic of single replacement reaction.

Therefore, The given reaction is a single replacement reaction
