In the balanced chemical equation for the formation of ammonia. n2 + h2 —–> nh3 the total sum of all the coefficients is
The Correct Answer and Explanation is:
The balanced chemical equation for the formation of ammonia is:
N2(g)+3H2(g)→2NH3(g)N_2(g) + 3H_2(g) \rightarrow 2NH_3(g)N2(g)+3H2(g)→2NH3(g)
To find the sum of all the coefficients in the equation, we add the coefficients of each substance involved in the reaction.
- The coefficient of N2N_2N2 is 1.
- The coefficient of H2H_2H2 is 3.
- The coefficient of NH3NH_3NH3 is 2.
Now, we sum the coefficients:
1+3+2=61 + 3 + 2 = 61+3+2=6
So, the total sum of the coefficients is 6.
Explanation of the balanced equation:
The equation represents the synthesis of ammonia (NH₃) from nitrogen gas (N₂) and hydrogen gas (H₂). According to the reaction, one molecule of nitrogen reacts with three molecules of hydrogen to form two molecules of ammonia.
In this equation, the law of conservation of mass is respected. This law states that matter cannot be created or destroyed in a chemical reaction. Therefore, the number of atoms of each element must be the same on both sides of the equation. Here, on the left side, there are 2 nitrogen atoms (from N₂) and 6 hydrogen atoms (from 3H₂), and on the right side, there are 2 nitrogen atoms (in 2NH₃) and 6 hydrogen atoms (in 2NH₃). This shows that the equation is balanced.
The coefficients of the balanced equation are crucial for calculating the amounts of reactants and products in stoichiometric calculations, such as finding the limiting reagent, yield, and percent yield in chemical reactions.
