a process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction.
Alkali metals<span> include </span>lithium<span>, sodium, potassium, rubidium, cesium and francium. These </span>metals<span> have large atomic radii and generally lose electrons during reactions. They have relatively soft textures, which makes them easy to mold, shape and dissect for </span><span>various uses</span>
The reduction reaction is the gain of electrons while oxidation reaction is the loss of electrons. For potassium ion(K+), the reaction should be K+ + e- ==> K. So the answer is (1).
Answer:
See explanation
Explanation:
The compound is acetylacetone. This compound is immiscible with water because it is completely nonpolar.
However the introduction of ammonia, leads to the ionization of the specie. In the presence of a base(such as NH3), the molecule acetylacetone is deprotonated and its corresponding anion is formed. This anion can now interact with water and become miscible with it.
Answer: Carbon nanotubes, especially multi walled carbon nanotubes, are so strong because they are a single chain of unbroken covalent carbon-carbon bonds.
