Answer:
The other may not be free.
Explanation:
In the polymer-supported reaction with methanol, the reaction will undergo at one hydroxyl group because others may not be free due to bonding with other molecules. The hydroxyl groups could be bonded with the polymer with the help of hydrogen bonding of molecules. The hydroxyl group has to be bonded to only the compatible molecules and free molecules.
<span>The solubility of solutes is dependent on temperature. When a solid dissolves in a liquid, a change in the physical state of the solid analogous to melting takes place. Heat is required to break the bonds holding the molecules in the solid together. At the same time, heat is given off during the formation of new solute -- solvent bonds.</span>
Answer:
In the other of increasing wavelength we arrange as
<em>X-rays</em>
<em>ultraviolet</em>
<em>green light</em>
<em>red light</em>
<em>infrared</em>
<em>radio waves</em>
<em></em>
Explanation:
In the electromagnetic spectrum, wavelength decreases with increase in the energy of the electromagnetic wave. Since the e-m wave spectrum is arranged in the order of increasing energy (decreasing wavelength) as: Radio wave; infrared; visible light; ultraviolet; x-rays; gamma rays. Within the visible light, the green light has more energy than the red light. Therefore, the arrangement should be in the reverse direction of their increasing energy.
Answer:
the answer is d only as
ca reacts
mg reacts
k is more reactive so no reaction
mg is less reactive than sodium
