The Photon is the "release" of energy in the form of light. Energy absorbed by the atom causes a change in energy of the electrons of a stable atom. This change forces an electron to move from one valance ring to another. The energy is released in the form of light called a photon. Depending on the amount of energy released and the valance the electron jumps to is what determines the light (photon) wave length. If an atom has too much light than it may disappear/explode.<span>

Answer: 10.3 mol/l
Explanation: Molality = concentration c = n/V
Amount of substance n = m/M = 150 g / 58.44 g/mol =
2,5667 mol . c = 2.5667 mol / 0.25 l = 10.2669 mol/l
c =
The answer is B, Genetic diversity because it is when they combine to form a new organism they both contribute their hereditary factors.
Answer:
Eªcell > 0; n = 2
Explanation:
The reaction:
I2 (s) + Pb (s) → 2 I- (aq) + Pb2+ (aq)
Is product favored.
A reaction that is product favored has ΔG < 0 (Spontaneous)
K > 1 (Because concentration of products is >>>> concentration reactants).
Eªcell > 0 Because reaction is spontaneous.
And n = 2 electrons because Pb(s) is oxidizing to Pb2+ and I₂ is reducing to I⁻ (2 electrons). Statements that are true are:
<h3>Eªcell > 0; n = 2</h3>
Answer:
E) 1, 2, and 3
Explanation:
50g H2O + 0.45g NaCl --> 50.45g saline solution
