The vapors of some chemicals used in the chemistry laboratory, especially isocyanates, can react and bond the contact lens to the eye.
(FYI - the family of isocyanates include Superglue..I wouldn't want to have been the person who discovered this unfortunate reaction!)
There are 0.25 kilometers in 250 meters
Answer:
i think it is letter b. rustability but not so sureeee
Answer:
The molecular structure affects solubility mainly biased on its polarity or bonded ions.
Explanation:
Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.
**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.
I hope this helps!
In mineralogy and crystallography, a crystal structure<span> is a unique </span>arrangement of atoms<span> in a </span>crystal. Atomic arrangement of atoms in this kind of structure usually very symmetrical and highly ordered. Causing the component within the structure is so strong and hard to break. <span>A </span>crystal structure<span> is composed of a unit cell, a set of </span>atoms arranged<span> in a particular way; which is periodically repeated in three dimensions on a lattice. </span>Crystal structure would be commonly found in solid compounds.
