Answer:
The answer to your question is 18 neutrons
Explanation:
Data
Number of neutrons = ?
Atomic mass = 35
Three energy levels
seven valence electrons
Process
1.- We know that this element is on the third period (3 energy levels)
2.- We also know that this element is located on group 7A (it is a halogen)
3.- From the previous information, we conclude that this element is Chlorine.
4.- Chlorine has an atomic number of 17.
5.- The number of Neutrons = Atomic mass - atomic number
= 35 - 17
= 18

Answer is: quantity of sulfur is 13 tons.
Chemical reaction: S(s) + O₂(g) → SO₂(g).
From chemical reaction: n(S) : n(SO₂) = 1 : 1.
n(S) = n(SO₂); amount of substance.
m(S) ÷ M(S) = m(SO₂) : M(SO₂).
m(S) : 32 g/mol = 26 t : 64 g/mol.
m(S) = (32 g/mol · 26 t) ÷ 64 g/mol.
m(S) = 13 t = 13000 kg; mass of sulfur.
