Answer:
2n^2 electrons
Explanation:
for example, the first level contain 2*(1^2) = 2 electrons, the second level contain 2*(2^2) = 8 electrons, etc
Answer:
32
i just looked it up honestly

Answer:
Hence the ions per mole are:
In one mole of Li2SO3 , the number of the atoms are
Explanation:
The formula of lithium sulfite is Li2SO3.
It contain Li+ and SO3(2-) ions.This can be represented by :
Hence one mole of Li2SO3 will give 2 Li+ ions and 1 SO3 (2-) ion.
Hence the ions per mole are:
Number of atoms in lithium sulfite depends upon the mass of the Li2SO3 present .
Li2SO3 = 93.94 g/mole
This mass is equal to 1 mole of Li2SO3
Now 1 mole of any substance contain Na atoms . This is known as Avogadro Number.
Hence , if 1 mole of Li2SO3 is present then it contains Na atoms
If other then 1 mole present then number of atoms are calculated by:
Here n = number of moles
if the mass of the compound is given then first calculate the number of moles.
Answer:
Areas at high latitudes have the coldest water.
Explanation:
Surface water receives its heat from the sun.
I took the test and it was right 100% :)
