The molar mass of aluminum sulftae is 342.14 g/mol.
Since the subscript shows that there are 3 sulfurs within the substance, the total mass of sulfur is 96.21g/mol
Now take the mass of the sulfur and divide it by the molar mass of aluminum sulfate, then multiply by 100:
(96.21/342.15)(100) = 28.1% mass composition of sulfate
B protons are positive atoms and are inside the nucleus
I'm pretty sure it's Newton's
Answer:
Homogeneous mixture.
Explanation:
On mixing with water, it dissolves completely in it, hence, being a homogenous mixture.

Quantum numbers are used to describe the location of electrons in atoms.
Principal quantum number(n) tells which energy shell the electrons reside in.
The first energy shell n = 1, second energy shell n = 2 and it goes on.
Azimuthal quantum number (l) states which orbital the electron is most likely to reside in. the number of orbitals in an energy shell depends on the principal quantum number. number of orbitals are from 0 to n-1
If l = 0, s orbital
l = 1 , p orbital
l = 2, d orbital
in 2nd energy shell the number of orbitals are 0,1 etc.
5s-
Principal quantum number n = 5
Azimuthal quantum number l = 0
6p
Principal quantum number n = 6
Azimuthal quantum number l = 1
4d
Principal quantum number n = 4
Azimuthal quantum number l = 2
