  • Atoms that loss or gain electrons are called ions. There are two types of ions: cations and anions.
  • Here, 2+ represents that Calcium (Ca) should gain 2 more electrons so that its number equals to that of protons.
  • 3- represents that Nitrogen (N) should loss 3 electrons to equivalent with the number of protons.
  • Here, anions are S^2-, P^3-, Se^2-, Br^-.
  • While cations are Cr^3+, Ag^+, Li^+, Ba^2+.
  • The number of protons of Magnesium (Mg) = 12
  • The number of nuetrons of Mg = 12
  • The number of electrons of Mg = 12

Hope you could get an idea from here.

In most cases of fischer esterification, the carboxylic acid is the more "valuable" piece and the alcohol is used in excess. let
Daniel [21]
There are a lot of separation processes. To name a few, these can be distillation, centrifugation, extraction, membrane or sorption process and many other. To know which is the best technique, you should know the property between two substances that have a stark difference. In this case, it is the polarity. Ethyl alcohol is more polar than ethyl ester and less dense. Thus, these two won't mix. So, take advantage of their density difference by decantation or centrifugation.

Consider a 100-gram sample of radioactive cobalt-60.
svetlana [45]

It will take 5.2 years to decay.

The half life of cobalt-60 is 5.2 years. The half life is the time taken for the mass of the substance to decrease by a half.

here, the amount of remaining substance is 50%,

so, (\frac{1}{2} )^{n} = 0.5

n. log (0.5) = log (0.5)

n = 1

So it would take 1 half lives to decay this much, which is 1 x 5.2 which is 5.2 years.

what do you mean by radioactive decay ?

The process through which an unstable atomic nucleus loses energy via radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A material that has unstable nuclei is considered as radioactive.
