Answer:
Less
Explanation:
Since [Cu(NH3)4]2+ and [Cu(H2O)6]2+ are Octahedral Complexes the transitions between d-levels explain the majority of the absorbances seen in those chemical compounds. The difference in energy between d-levels is known as ΔOh (ligand-field splitting parameter) and it depends on several factors:
- The nature of the ligand: A spectrochemical series is a list of ligands ordered on ligand strength. With a higher strength the ΔOh will be higher and thus it requires a higher energy light to make the transition.
- The oxidation state of the metal: Higher oxidation states will strength the ΔOh because of the higher electrostatic attraction between the metal and the ligand
A partial spectrochemical series listing of ligands from small Δ to large Δ:
I− < Br− < S2− < Cl− < N3− < F−< NCO− < OH− < C2O42− < H2O < CH3CN < NH3 < NO2− < PPh3 < CN− < CO
Then NH3 makes the ΔOh higher and it requires a higher energy light to make the transition, which means a shorter wavelength.

Answer:
<h3>The answer is 5.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 10 g
volume = 2 mL
We have
We have the final answer as
<h3>5.0 g/mL</h3>
Hope this helps you
Amu or also known as atomic mass unit is a SI unit that is used in chemistry to identify the total of the mass of neutrons and protons. In this case,a carbon-12 has a mass of amu. amu is equivalent to grams per mole. In this case, the mass of 13.2 amu is 13.2 grams per mole

<h3>The scientific method</h3>
The scientific method refers to systematic methods employed by scientists in their quest for discoveries and explanation of phenomena.
The scientific method includes:
- Observation and formulation of questions
- Developing a hypothesis
- Conducting experiments
- Formulation of theories based on experiments
- Conducting further experiments and research
- Formulation of laws.
Thus, the characteristics of science include:
- relies on evidence
- uses testable ideas
- leads to ongoing research
Therefore, making moral judgments or decisions is not a characteristic of science.
