2HF + Na2SiO3 ----> 2NaF + H2SiO3 is the balanced equation.
2 moles of HF form 2 moles of NaF
therefore 0.508 Mol HF forms 0.508 mol of NaF
In grams this is 0.508( rel atomic mass of Na + RAM of F)
= 0.508 (22.99+19)
= 21.33 grams
Element name: Neon
element symbol: Ne
atomic number: 10
atomic mass: 20.1797
number of protons: 10
number of neutrons: 10
number of electrons: 2,8
interesting fact: the name means new, and it is pulled out of the air.
for the rest just add a neon bohr model ig

It seems that you have missed the necessary options for us to answer this question so I had to look for it. But anyway, here is the answer. If Dr. John Sutherland is correct, the one that was necessary <span> for inert carbon atoms to become part of the chemistry of earth is CYANIDE. Hope this helps.</span>
Answer:
It really dpened on how you l.ook at it look up the definition of POH and that should help
