Answer:
The energy of electromagnetic radiation increases as its frequency increases.
The frequency and wavelength of electromagnetic radiation are inversely proportional.
Explanation:
According to Max Plank's equation, the energy of electromagnetic radiation is given by E=hf where h= Plank's constant and f= frequency of the electromagnetic radiation. This means that the energy and frequency of electromagnetic radiation and its energy are related by a direct proportion. As frequency of the electromagnetic radiation increases, the energy of the radiation increases also.
However, frequency and wavelength of electromagnetic radiation are inversely related. The frequency decreases with increasing wavelength of electromagnetic radiation.
Answer:
H-H < C-H < O-H < F-H
Explanation:
The polarity of a bond is the difference in the electronegativity of the elements. This property is the tendency of the atom to gain an electron and form an anion, or when in covalent bond (sharing electrons), to have the electron close to it.
As higher is the atomic radius, as difficult it is to the atom to gain an electron because the attractive force will be less effective. So, the electronegativity increases from the bottom to top, and from the left to right in the periodic table.
So, when the bond is between the same element, the polarity is 0, such as H-H. H has a low electronegativity, then it comes C, O, and F, so, the order of increasing of polarity is:
H-H < C-H < O-H < F-H
The atom consists of a nucleus with electrons orbiting at specific energy levels
It would be nice if u add spacing between the sentences.
You could argue that any solution with water in it has an equilibrium in it of some sort. If a solution is over saturated there is an equilibrium between the dissociated and solid solute (for example NaCl(s)⇄Na⁺(aq)+Cl⁻(aq) when in water). Even if the solution is not over saturated, water always has the reaction 2H₂O(l)⇄H₃O⁺(aq)+OH⁻(aq) since water can act as both an acid and a base (this reaction is also always at equilibrium and the equilibrium constant is 1×10⁻¹⁴).
Since we usually ignore the autoionization of water (unless dealing with acid base chemistry), I think the answer your teacher is looking for is over saturated solutions.
I hope this helps. Let me know if anything is unclear or if you need a different answer.
Answer:
- Elimination
- Elimination
- Zaitsev
- Zaitsev
- Carbocation
Explanation:
- The mechanism is generally accepted to always operate via an ELIMINATION step-wise process.
- The ELIMINATION mechanism process will always produce (after dehydration) a ZAITSEV style alkene as major product
- The driving force for the production of this ZAITSEV style alkene product is generally going to be determined by stability of the CARBOCATION
Elimination mechanism is the removal of two substituents from a molecule in either a one- or two-step mechanism
Carbocation is a molecule containing a positive charged carbon atom and three bonds
