A bigger difference in electronegativity between two molecules means higher polarity and a stronger bond. Electronegativity increases on the periodic table as you go up a group and to the right. Ex: CsF has a very high polarity
Plastic packaging requires oil to create it
The vapor pressure is EQUAL TO the outside air pressure.
Answer:
D - Hydroxide Ion (OH-)
Explanation:
A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.
