<span>According to octet rule, atoms with an atomic number less than 20 tend to combine with other atom such that both of these atoms have eight electrons in their valence shells, which gives them the same electronic configuration as that of noble gas.
However, there are few compound that donot obey octel rule. Among the elements mentioned above i.e. oxygen and helium obeys octet rule.
In case of nitrogen, oxide of nitrogen (like NO and NO2) have incomplete octet.
While there are few compounds of Br wherein Br has expanded octet. For example, in BrF5, Br has 12 electrons in valence shell. </span>
So diffusion is inversely proportional to mass !
so as mass of the particle increases, diffusion decreases !
Answer:
The speed of light is the speed at which light travels. No, an object cannot move at the speed of light.
Explanation:
The speed of light is 186,000 miles per second. An object with mass cannot move at the speed of light since it would take an infinite amount of energy to achieve that velocity, since only massless particles can travel at the speed of light. Also, you would have to factor in air friction, meaning even if an object were to reach such high speeds, it would instantly disintegrate.
The compounds will yield Positive results for the permanganate, ninhydrin, and ceric ammonium nitrate tests are
permanganate test= ethene,
ninhydrin=aspasyic acid Phenylalanine
ceric ammonium nitrate test= methanol
<h3>What is a compound?</h3>
Generally, A compound is simply defined as a substance made up of two or more different chemical elements held together by chemical bonds that are difficult to break.
In conclusion, For the permanganate test= ethene,
ninhydrin=aspasyic acid Phenylalanine
ceric ammonium nitrate test= methanol
