Answer The ethanol is stabilized by strong intermolecular forces between the molecules.wer:
Explanation:
During the phase change represented by the heat of fusion the temperature does not change. The molecules in the liquid state has a higher degree of freedom but are stabilized by the strong hydrogen bonding requiring a larger into of energy to separate the molecules than the heat of fusion.
I think so ( for solids ) because you know when you melt chocolate it turns into a liquid and liquids allways move around together and it can't get smaller either so, I think you are right.
Ionization energies evidence for the quantization of energy levels in atoms, as described by the Schrodinger wave mechanical model of the atom because it takes a specific amount of energy to remove the definite one electron from an atom.
Explanation:
- Ionization energies evidence for the quantization of energy levels in atoms, as described by the Schrodinger wave mechanical model of the atom because it takes a specific amount of energy to remove the definite one electron from an atom.
- There is an approximate amount of energy which is needed to overcome the attractive force between the electrons and nucleus.
- If you put less than the required ionization energy, then the electrons can not be removed.
<u>The Concept:</u>
We are given the density of a sample of the metal = 11.4 grams / cm³
and we need to find the volume occupied by a sample of 30.5 grams
For this solution, we will use dimensional analysis
from the given information, we can also say that the density of the metal is:
1 cm³ / 11.4 grams
If we multiply this value by 30.5 grams, the 'grams' in the numerator and the denominator will cancel out and we will be left with the volume occupied by 30.5 grams of the metal
<u>Solving for the volume:</u>
X 30.5 grams = (30.5 / 11.4) cm³
Volume of 30.5 grams of the sample = 2.68 cm³
