Answer:
If you mean Lewis dot diagrams, aka electron-dot diagrams, then these are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule.
Explanation:
By Boyle's law:
P₁V₁ = P₂V₂
300*75 = P<span>₂*50
</span>P<span>₂*50= 300*75
</span>
P<span>₂ = 300*75/50 = 450
</span>
P<span>₂ = 450 kiloPascals.
The pressure has increased as a result of compression of gas.
Boyle's Law supports this observation.</span>
Different: The weak nuclear force is responsible for radioactive decay within an atom of a substance, while the electromagnetic force causes electrostatic force between charged particles.
Different: The weak force has a very small range of effectiveness (where the force can be felt) while the electromagnetic force has an infinite range.
Same: Both forces act within an nucleus, or on a nuclear level.
Same: The weak nuclear force is mediated by charged particles called bosons, and the electrostatic force is only present within charged objects
The last one may be a bit of a stretch but I hope this helped a bit!
Why do teachers give such hard questions? anyways hopefully your question will get answered! (btw i also need the points but yeah gl!!!)
