Answer:
formula units
Explanation:
is potassium chlorate. It is an ionic compound containing potassium, chlorine and oxygen. The ion in potassium chlorate are held together by the ionic bonds in the lattice structure.
A representative particle may be defined as the smallest unit for which the substance exists in its natural form. For most of the elements, atom is the representative particle. Molecule is the representative particle for diatoms and molecular compounds. But for ionic compounds such as , NaCl, etc. . the representative particle is its formula units.

A) 80 g
B) 40 g
C) 120 g
D) 160 g
Answer:
make me brainliest pls :)
Explanation:
Science is both a body of knowledge and a process. In school, science may sometimes seem like a collection of isolated and static facts listed in a textbook, but that's only a small part of the story. Just as importantly, science is also a process of discovery that allows us to link isolated facts into coherent and comprehensive understandings of the natural world.
Science is exciting. Science is a way of discovering what's in the universe and how those things work today, how they worked in the past, and how they are likely to work in the future. Scientists are motivated by the thrill of seeing or figuring out something that no one has before.
Science is useful. The knowledge generated by science is powerful and reliable. It can be used to develop new technologies, treat diseases, and deal with many other sorts of problems.
Science is ongoing. Science is continually refining and expanding our knowledge of the universe, and as it does, it leads to new questions for future investigation. Science will never be "finished."
Science is a global human endeavor. People all over the world participate in the process of science. And you can too!
Answer:-
Ca-Cl
Explanation:-
The more the difference in electronegativity more the polar bond.
In case of Ca-Cl the difference = 3.16 - 1= 2.16
It is more than all the other combinations given.
Hence Ca-Cl is the most polar covalent bond.
The distance of the earth to the sun in Mm = 1.5 x 10⁵
<h3>Further explanation</h3>
Given
The distance of the earth to the sun : 1.50 x 10⁸ km
Required
The distance in Mm
Solution
In converting units we must pay attention to the conversion factor.
the conversion factor :
1 kilometer(km) = 10⁻³ megameter(Mm)
So the distance conversion :
1.5 x 10⁸ x 10⁻³ = 1.5 x 10⁵ Mm
