What is the molarity of a solution of 14.0 g NH4Br in enough H2O to make 150 mL of solution?
kiruha [24]
The molarity of a solution equals to the mole number of the solute/the volume of the solution. For NH4Br, we know that the mole mass is 98. So the molarity is (14/98) mol /0.15 L=0.95 mol/L.

When you have a free metal ion, how do the energies of these orbitals relate to one another (are they the same, different, etc.)
7nadin3 [17]

Answer:

The energy of the orbitals are the same

Explanation:

For a free metal ion, all the d-orbitals are of the same energy. The five d-orbitals are said to be five fold degenerate in the free metal ion. Hence all the d-orbitals will possess the same energy irrespective of which one is first filled.

In an octahedral or tetrahedral crystal field, the d-orbitals will loose their degeneracy and become different in energy based on their orientation towards the ligands.

Katyanochek1 [597]

The observation, in this case, is quantitative.

<h3>Quantitative observation</h3>

Quantitative observations are observations that can be recorded based on quantitative data. In other words, they are observations that can be assigned numerical values.

Quantitative observations are as opposed to qualitative observations because the former cannot be assigned numerical values. They can be ranked or qualified.

In this case, Danielle and Heather could assign numbers to the length, width, and height of the tank in order to calculate its volume.
