Blank N2 + Blank H2 = Blank NH3
Blank N2 + 3 H2 = 2 NH3
The balanced chemical equation for the reaction between nitrogen gas (N2) and hydrogen gas (H2) to form ammonia gas (NH3) is as follows:
N2 + 3H2 → 2NH3
To determine the coefficients, or the numbers placed in front of the molecules to balance the equation, we need to follow the steps below:
Step 1: Count the number of atoms of each element on both sides of the equation.
On the left-hand side (reactants):
- Nitrogen (N): 2 (since N2 has 2 nitrogen atoms)
- Hydrogen (H): 6 (since 3H2 has 6 hydrogen atoms)
On the right-hand side (products):
- Nitrogen (N): 2 (since 2NH3 has 2 nitrogen atoms)
- Hydrogen (H): 6 (since 2NH3 has 6 hydrogen atoms)
Step 2: Determine the smallest whole number ratio of atoms by dividing the atom counts by their greatest common divisor (GCD).
Dividing both sides by 2 (GCD of 2 and 6), we get:
- Left-hand side: N2 + 3H2
- Right-hand side: 2NH3
Therefore, the balanced chemical equation is:
N2 + 3H2 → 2NH3
To fill in the blanks in the chemical equation:
Blank N2 + Blank H2 = Blank NH3
we need to balance the equation by determining the appropriate coefficients for each compound.
The equation represents the reaction between nitrogen gas (N2) and hydrogen gas (H2) to produce ammonia (NH3).
To balance the equation, we start by ensuring that the number of atoms of each element on both sides of the equation is equal.
Let's proceed step-by-step:
Step 1: Balance the nitrogen atoms:
There are two nitrogen atoms on the left side (N2) and one nitrogen atom on the right side (NH3). To equalize the number of nitrogen atoms, we put a coefficient of 2 in front of NH3.
2NH3
The equation becomes:
Blank N2 + Blank H2 = 2NH3
Now, let's balance the hydrogen atoms.
Step 2: Balance the hydrogen atoms:
There are two hydrogen atoms on the left side (H2) and six hydrogen atoms on the right side (2NH3). To equalize the number of hydrogen atoms, we put a coefficient of 3 in front of H2.
3H2
The equation becomes:
Blank N2 + 3H2 = 2NH3
Now that we have balanced the equation, the final balanced chemical equation is:
N2 + 3H2 = 2NH3
