Find the atoms of 52u of helium ​

Here, we have been given the the amount of helium to be 52 amu.

Thus,

$ \red{\leadsto}$ Hence, the number of atoms will be 13 atoms.

Explanation:

Therefore in 52 moles of Argon 3.13196×1025 atoms are present. Therefore, in 52 u of Helium 13 atoms are present. Therefore, in 52 g of Helium 7.83×1024 atoms are present.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
