Answer:
CaO + SO 3 → CaSO. 4
This is an acid-base reaction (neutralization): CaO is a base, SO 3 is an acid.
The atomic number is the same as the amount of electrons and protons. For example:
Oxygens atomic number is 8 so the proton and electron count is 8.
Hydrogens atomic number is 1 so the proton and electron count is 1.
Molecular formula: C8H6N2
Empirical formula: C4H3N
According to the balanced reaction equation:
2KClO3→ 2KCl + 3O2
from this equation, we can see that the molar ratio between KCl & O2 is 2 : 3
so, 2 moles of KCl will need 3 moles of O2
∴ 7.16 moles of KCl will need X moles of O2
∴number of moles of O produced = 7.16 * 3 / 2
= 10.74 moles
