Answer:
no no no who are these some look good but are black what is this
The empirical formula is XeO₃.
<u>Explanation:</u>
Assume 100 g of the compound is present. This changes the percents to grams:
Given mass in g:
Xenon = 73.23 g
Oxygen = 26.77 g
We have to convert it to moles.
Xe = 73.23/
131.293 = 0.56 moles
O = 26.77/ 16 = 1.67 moles
Divide by the lowest value, seeking the smallest whole-number ratio:
Xe = 0.56/ 0.56 = 1
O = 1.67/ 0.56 = 2.9 ≈3
So the empirical formula is XeO₃.
If you're looking for the balances equation to this the answer is

proton- a stable particle with positive charge equal to the negative charge of an electron
electron cloud- the system of electrons surrounding the nucleus of an atom.
nucleus- A nucleolus is the largest structure within the nucleus of a eukaryotic cell.
electron- Electrons are the smallest of the particles that make up an atom, and they carry a negative charge.
neutron- a subatomic particle with 0 charge and mass about equal to a proton; enters into the structure of the atomic nucleus.
