Question

In the following reaction, the product is ammonia, NH3. According to the balanced equation, how many hydrogen atoms total are in the final products?
N2 + 3H2 2NH3
A. 2
B. 3
C. 5
D. 6

Answer 1

6Hydrogen atoms beacause there are 2NH3

Answer 2

Answer:

D. 6

Explanation:

To balance a chemical equation, you need to have the same amount of startings and products.

Both sides of the equation must have the same amount of atoms.

To make ammonia, you need to react to N2 with H2. Both are diatomic substances.

So, if you have N2 + 3H2 = 2NH3 you star with two molecules of hydrogen. Each molecule has two atoms.

3x2=6 you have 6 atoms of Hydrogen.
