Explanation:

Data

Chemical reaction

                   (NH₄)₂CO₃  ⇒   NH₃  +  CO₂  + H₂O

               Reactants    Elements     Products

                      2            Nitrogen             1

                       1            Carbon                1

                       8           Hydrogen            5

                       3           Oxygen                3

This reaction is unbalanced

                   (NH₄)₂CO₃  ⇒   2NH₃  +  CO₂  + H₂O

               Reactants    Elements     Products

                      2            Nitrogen             2

                       1            Carbon                1

                       8           Hydrogen            8

                       3           Oxygen                3

Now, the reaction is balanced,

The coefficient for Carbon dioxide is 1

Answer 2

Answer:

The coefficient for carbon dioxide (CO2) is 1 (option A) is correct.

Explanation:

Step 1: The unbalanced equation

(NH4)2CO3 ⇒ NH3 + CO2 + H2O

Step 2: Balancing the equation

(NH4)2CO3 ⇒ NH3 + CO2 + H2O

On the left side, we have 2x N (in (NH4)2CO3), on the right side we have 1x N (in NH3). To balance the amount of N on both sides we have to multiply NH3 on the right side by 2. Now the equation is balanced.

(NH4)2CO3 ⇒ 2NH3 + CO2 + H2O

The coefficient for carbon dioxide (CO2) is 1 (option A) is correct.
