<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
Answer:
Both decrease the energy of the atomic orbitals to form the molecule by their overlap
Explanation:
Many molecules are not described correctly by Lewis theory. For example, diborane (B2H6), which is an electrodeficient compound: there are not enough valence electrons to be able to assign a Lewis structure.
The theory of binding and anti-binding orbitals describes molecular orbitals, whose atomic orbitals overlap to form them. Two atomic orbitals overlap giving a binding orbital molecular orbital. In the binder, the electrons that occupy it have a high possibility of being located between the atoms, so filling stabilizes the molecule. In an anti-binding orbital, the electrons that occupy it have a low probability of being located between the atoms, so that their filling destabilizes the molecule.
The interaction between two atomic orbitals is greater the greater their overlap and the smaller their energy difference.
Answer:
it lost 900J of energy I will assume and that would mean the change in energy is -900J
