It is not practical to use in scientific experimentation to test the effect of an octave on the quality of a song. There are so many scientific experimentations to test the effect that can be count practical like the color on brain waves and function, adrenaline on the response time of carnivores, nutrients on the gender of offspring and much more. Scientific Experimentation has an organized process and detailed series of steps to reject or validate a hypothesis. It is also a third step in scientific method. Researcher use experimentation to test a new hypothesis or theories to approve or support and disapprove them.

Answer:
C. ammonia, nitrogen gas, nitrous oxide, nitrite, nitrate
Explanation:
To establish the oxidation number of nitrogen in each compound, we know that the sum of the oxidation numbers of the elements is equal to the charge of the species.
Nitrite ion (NO₂⁻)
1 × N + 2 × O = -1
1 × N + 2 × (-2) = -1
N = +3
Nitrous oxide (NO)
1 × N + 1 × O = 0
1 × N + 1 × (-2) = 0
N = +2
Nitrate ion (NO₃⁻)
1 × N + 3 × O = -1
1 × N + 3 × (-2) = -1
N = +5
Ammonia (NH₃)
1 × N + 3 × H = 0
1 × N + 3 × (+1) = 0
N = -3
Nitrogen gas (N₂)
2 × N = 0
N = 0
The order of increasing nitrogen oxidation state is:
C. ammonia, nitrogen gas, nitrous oxide, nitrite, nitrate
