Answer: Option (c) is the correct answer.
Explanation:
A physical model is defined as a model which represents how atoms are bonded together and structure of a molecule.
Physical model shows the three dimensional structure of a molecule. Physical models helps to easily understand and visualize the configuration, single bonds, double bonds and total atoms within a molecule.
Thus, we can conclude that given structure of carbonic acid best describes a physical model.
Answer: A
Explanation:
Considering the order of filling electrons into orbitals, movement from a higher to a lower energy level results in the emission of a photon with energy equal to the energy difference between the two energy levels. However, the energies of different orbitals are close together for high values of n (principal quantum number). Their relative energies may change significantly when they form ions. This implies that energy levels are better separated and have high differences in energy for low values of n. Hence the answer. This means that photons transiting between these Lowe n levels will posses higher photon energy due to larger energy difference between levels.

• </span>Volume of the marshmallow:
V = 2.75 in^3 (but, 1 in^3 = 16.39 cm^3)
V = 2.75 × 16.39 cm^3
V = 2.75 × 16.39 cm^3
V = 45.0725 cm^3
• Density:
d = 0.242 g/cm^3
<span>• </span>Mass:
m = d × V
m = (0.242 g/cm^3) × (45.0725 cm^3)
m = (0.242 g/cm^3) × (45.0725 cm^3)
m = 10.907545 g
m ≈ 10.9 g <——<span>— this is the answer.
I hope this helps. =)

The last option, "Energy that flows from a hot mug of tea to a cold hand." Hope this helps!
(This is because heat is the transfer of energy that you can well, feel. In simple terms. For this question and other like it you can do process of elimination because the only one that involves heat, is the last option.)
Answer:
The total amount of Au is $ 
Explanation:
Given that,
Mass of 1.0 ml of Au 
Total volume of water in oceans 
We need to calculate the volume in ml
Using given volume
We need to calculate the total mass of Au
Using given data
So, The total mass of Au is 
The mass will be in ounce,
The total amount of the Au Will be
Hence, The total amount of Au is $
