J. Dorman probably was the scientist.
I have a question too. Can you please help me with that? I have a test tomorrow. Thank you!
1. True or False? When you charge your laptop, you are separating charges in the laptop battery.
2. True or False? When you use your laptop, the battery becomes more neutral as it runs low on power.
Answer : Molecules.
Explanation : Elements are the class of pure substances that cannot be physically separated; but they are made up of the same atoms of the same elements. When two or more elements are combined chemically with a chemical bond they become physically inseparable; which is called as a Molecule. Therefore, the term which represents represents a pure substance that can be separated chemically, but cannot be separated physically, that is made up of two or more different atoms is a molecule.
A compound is made up many different molecules. The main difference between the compound and the molecule is that a compound must have at least two different elements. So, it can be said that a compound is a type of molecule.
Mixtures are made up of different compounds which can be physically separated.
Ionic compounds are soluble in polar solvent that's why, polar solvent like water decrease the electrostatic forces of attraction, resulting in free ions in aqueous solution.
The year is 365 days (assume). The day is 86400 secons (60*60*24). The product is
3'153'600 seconds.
Below are the choices that can be found elsewhere:
<span>He wanted to show that warmed crystals radiate heat.
He wanted to show that the crystals emit X-rays.
He wanted to show that the crystals emit light after absorbing light.
He wanted to show that the crystals would become radioactive when they were exposed to sunlight.

The answer is "<span>He wanted to show that the crystals emit X-rays."</span>
