The phase change that releases the most energy is deposition, when gas turns into a solid. It takes the absorption of energy to melt a solid into a liquid, and even more energy to vaporize the liquid into a gas. Hence, the reverse process (from solid to gas) will result in the greatest release of energy.
Answer:
Frequency = 0.8×10¹⁵ Hz
Explanation:
Given data:
Frequency of photon = ?
Wavelength of photon = 3.75 ×10⁻⁷ m
Solution:
Formula:
Speed of photon = wavelength × frequency
Frequency = speed of photon / wavelength
Now we will put the values in formula.
Frequency = 3 ×10⁸ m/s / 3.75 ×10⁻⁷ m
Frequency = 0.8×10¹⁵ s⁻¹
s⁻¹ = Hz
Frequency = 0.8×10¹⁵ Hz

Answer:
NADPH
Explanation:
because it is in a dark stage
Answer: cations together in a sea of electrons
Explanation:
Metallic bonding is the type of chemical bonding occurs between the atoms of a metals. In this type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions called as cations.
These de-localized electrons are the valence electrons of metal atoms which are shared between them.
In ionic bonding , the cations are attracted to anions where cations are formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
