Most fertilizers contain ammonia (NH3). Ammonia forms when hydrogen reacts with nitrogen. Which equation correctly represents the chemical reaction that forms ammonia?
A.
3H2 + N2 → NH3
B.
H2 + N2 → 2NH3
C.
H2 + N2 → NH3
D.
3H2 + N2 → 2NH3
D. 3H2 + N2 → 2NH3
The correct equation that represents the chemical reaction forming ammonia is:
B. H2 + N2 → 2NH3
To determine the equation that correctly represents the chemical reaction forming ammonia (NH3) by the reaction of hydrogen (H2) with nitrogen (N2), we need to balance the equation by ensuring that the number of atoms on both sides of the equation is equal.
First, let's examine the number of hydrogen (H) atoms on both sides. The left side of the equation has three hydrogen atoms (3H2), while the right side only has one ammonia molecule (NH3). So, we need to multiply NH3 by three to balance the hydrogen atoms, as shown in options A and B.
Next, let's consider the number of nitrogen (N) atoms. The left side of the equation has one nitrogen molecule (N2), and the right side has one ammonia molecule (NH3). Therefore, the nitrogen atoms are balanced in each option.
Considering the above analysis, the equation that accurately represents the chemical reaction forming ammonia (NH3) is:
D. 3H2 + N2 → 2NH3
