Answer:
7.71x10^23 molecules
Explanation:
Avogadro's # = 6.022x10^23
1.28 mol SiO2 x 6.022x10^23/ 1 mol SiO2 = 7.71x10^23 molecules
The inert gases like neon,argon ,krypton have complete shells
Answer:
the equation is unbalanced
Answer:
pH = 0.35
Explanation:
For a strong acid, all of the acid dissociates into H3O+, and pH = -log[H3O+], where [H3O+] = [HClO3] = 0.45 M.
Answer:
10 Kelvin
Explanation:
this is so simple...
if you want to raise the temp from 270K to 280K just add 10K
