N2+3h2=2NH3 what is the number of atoms of the answer.
The Correct Answer and Explanation is:
To analyze the reaction ( \text{N}_2 + 3\text{H}_2 \rightarrow 2\text{NH}_3 ) and determine the total number of atoms, we can break down the equation step by step.
Chemical Reaction Breakdown
- Reactants:
- Nitrogen (( \text{N}_2 )): The molecule consists of 2 nitrogen atoms.
- Hydrogen (( \text{H}_2 )): The equation specifies that there are 3 molecules of hydrogen, each containing 2 hydrogen atoms. Therefore, the total number of hydrogen atoms is ( 3 \times 2 = 6 ). Adding these together, the total number of atoms in the reactants is:
[
2 \, (\text{from } \text{N}_2) + 6 \, (\text{from } 3\text{H}_2) = 8 \, \text{atoms}
]
- Products:
- Ammonia (( \text{NH}_3 )): The equation shows that 2 molecules of ammonia are produced. Each ammonia molecule contains 1 nitrogen atom and 3 hydrogen atoms. Thus, for 2 molecules:
- Nitrogen: ( 2 \times 1 = 2 ) atoms
- Hydrogen: ( 2 \times 3 = 6 ) atoms
[
2 \, (\text{from } 2\text{NH}_3) + 6 \, (\text{from } 2\text{NH}_3) = 8 \, \text{atoms}
]
Conclusion
In summary, both the reactants and products contain a total of 8 atoms. The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction; hence, the number of atoms before the reaction (8) equals the number after the reaction (8).
To conclude, in the balanced chemical reaction ( \text{N}_2 + 3\text{H}_2 \rightarrow 2\text{NH}_3 ), the total number of atoms involved in the reaction is 8, confirming the balance of the equation and the principle of conservation of mass.
