Chapter 4: Q4.93P (page 182)

Predict the product(s) and write a balanced equation for each of the following redox reactions:

(a)N2(g)+H2(g)鈫�

(b)NaClO3(s)鈫�螖

(c)Ba(s)+H2O(l)鈫�

Short Answer

Expert verified

The product and the balance equation of the given reactions are:

(a)N2(g)+3H2(g)鈫�2NH3(g)

(b)NaClO3(s)鈫�螖2NaCl(s)+3O2(g)

(c)Ba(s)+2H2O(l)鈫�Ba(OH)2(aq)+H2(g)

Step by step solution

01

Determine the product of the equation (a)

The given redox reaction is a combination reaction.

Nitrogen combines with hydrogen and forms ammonia.

The given reaction is:

N2(g)+H2(g)鈫�

The balanced reaction is:

N2(g)+3H2(g)鈫�2NH3(g)

02

 Step 2: Determine the product of the equation (b)

The given redox reaction is a decomposition reaction.

Sodium chloratedecomposes and forms sodium chloride and oxygen.

The given reaction is:

NaClO3(s)鈫�螖

The balanced reaction is:

NaClO3(s)鈫�螖2NaCl(s)+3O2(g)

03

Determine the product of the equation (c) 

The given redox reaction is a displacement reaction.

Hydrogen is displaced by Barium to formBa(OH)2

The given reaction is:

Ba(s)+H2O(l)鈫�

The balanced reaction is:

Ba(s)+2H2O(l)鈫�Ba(OH)2(aq)+H2(g)
