Answer:
Radio waves
Explanation:
Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
Energy and oreantation its one if not bolth of those
Answer:
Option b) polyatomic ions
Explanation:
Polyatomic ions are ions consisting of two or more atoms.
From the question given above, we can see that each ions consist of more than one atom as shown below:
Ions >>>>>> Number of atom present
NH4+ >>>>> 2
CO32− >>>> 2
PO43− >>>> 2
Thus, we can say that the above ions are polyatomic ions.
Answer:) is related to the change in free energy of the reaction--d
Explanation:
For any reaction that is taking place at any moment the change in Gibbs Free Energy is related to the reaction quotient as
ΔG=ΔG⁰+RTlnQ
where R-Universal Gas Constant, T- Temperature in Kelvin, Q is the reaction quotient
Now when the system is in equilibrum, ΔG⁰ which is the standard Gibb's Free Energy,is then defined as
ΔG⁰=−RTlnK ,
where K is the equilibrium constant. because ΔG becomes 0 and reaction quotient Q = K
The equilibrum constant is related to the change in free energy of the reaction.
because when ΔG is negative, the value of K is high which leads to a spontaneous. reaction
when ΔG is positive, the value of K is low, which leads to a spontaneous. reaction in the opposite direction.
As the length of carbon chain increases the forces which hold the atoms also increases . Ethanol is a liquid due to higher bond energy
