Question

types of molecules
what type of molecules are inorganic?
what types of molecules are organic?

inorganic molecules
water molecules →
what does polarity mean in water molecules?
water is → allows
(substances are polar)
what is cohesion?
what is adhesion?

organic molecules
macromolecules:

compounds will react with each other to create other molecules:
show a chemical formula producing water (identify the reactants and the products)

Explanation:

Inorganic molecules generally lack carbon - hydrogen bonds, like water. Organic molecules have carbon - hydrogen bonds. Water is polar due to unequal electron sharing, which allows hydrogen bonding. Cohesion is the attraction between like water molecules, adhesion is between unlike molecules. The first organic molecule shown is a carbohydrate (function: energy source), the second is an amino - acid (function: building blocks of proteins), the third is a fatty acid (function: energy storage), the fourth is a nucleotide (function: genetic information storage and transfer). A common chemical formula producing water is $2H_2 + O_2
ightarrow2H_2O$, where hydrogen and oxygen are reactants and water is the product.

Answer:

• Inorganic molecules: Compounds without carbon - hydrogen bonds like water.
• Organic molecules: Compounds with carbon - hydrogen bonds.
• Water polarity: Unequal electron sharing creating a dipole.
• Cohesion: Attraction between like water molecules.
• Adhesion: Attraction between unlike molecules.
• First organic molecule: Carbohydrate, energy source.
• Second organic molecule: Amino - acid, building blocks of proteins.
• Third organic molecule: Fatty acid, energy storage.
• Fourth organic molecule: Nucleotide, genetic information storage and transfer.
• Chemical formula for water production: $2H_2 + O_2

ightarrow2H_2O$, reactants are $H_2$ and $O_2$, product is $H_2O$.
