                       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

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.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
