The sample with the largest number of oxygen atoms will be calcium perchlorate.
<h3>Number of atoms in a compound</h3>
Since we are not looking at the number of moles, the mass of the compounds has no bearing on the number of atoms of oxygen.
- The chemical formula for carbon dioxide is
. Thus, it has 2 atoms of oxygen. - The chemical formula for potassium chlorate is
. Thus, it has 3 oxygen atoms. - The chemical formula for calcium perchlorate is
. Thus, it has 8 atoms of oxygen. - The chemical formula for sodium hydroxide is NaOH. Thus, it has 1 atom of oxygen.
Therefore, the compound with the largest number of oxygen atoms is calcium perchlorate.

Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Answer:
The answer to your question is: a = 2.1 m/s²
Explanation:
Data
Acceleration : ?
Mass = 2000 kg
Force = 4200 N
Formula
Newton's second law of motion F = ma
a = F / m
Substitution
a = 4200 N / 2000 kg
a = 2.1 m/s²
Answer:
Ionization energy increases going left to right across a period and increases from bottom to top in a group
Electron affinity increases when going up a group
If we are excluding noble gases (aka group 8/18), Chlorine is the element that has the greatest electron affinity. This is because Fluorine's 2p orbital is limited and packed which doesn't quite allow sharing of the orbital with extra electrons easily, while Chlorine has a 3p orbital allowing more space for electrons, where the orbital electrons would be inclined to do so.
Helium is the element with the greatest ionization energy since it's at the top and energy (from Oganesson to Helium) increases when going across a period (from Hydrogen to Helium).
