Inorganic Compounds & Solutions

Question 1

Inorganic compounds

Answer 1

Compounds that lack carbon and are structurally simple. Their molecules have only a few atoms and cannot be used by cells to perform complicated biological functions

Question 2

Water

Answer 2

The most important and abundant inorganic compound in all living systems. It’s polarity makes it an excellent solvent for other ionic and polar substances, gives water molecules cohesion, and allows water to resist temperature changes

Question 3

Solution

Answer 3

A substance called the solvent dissolves another substance called the solute

Question 4

Hydrophilic

Answer 4

Solutes that are charged or contain polar covalent bonds, which means they dissolve easily in water

Question 5

Hydrophobic

Answer 5

Molecules that contain mainly nonpolar covalent bonds. They are not very water soluble

Question 6

Hydrolysis

Answer 6

Decomposition reactions that break down large nutrient molecules into smaller molecules by the addition of water molecules

Question 7

Dehydrated synthesis reaction

Answer 7

When two smaller molecules join to form a larger molecule. A water molecule is one of the molecules formed

Question 8

Mixture

Answer 8

A combination of elements or compounds that are physically blended together but not bound by chemical bonds

Question 9

Colloid

Answer 9

A solution with solute particles that are large enough to scatter light

Question 10

Suspension

Answer 10

The suspended material may mix with the liquid or suspending material for some time, but eventually it will settle out

Question 11

Dissociate

Answer 11

When inorganic acids, bases, or salts dissolve in water, they separate into ions and become surrounded by water molecules

Question 12

Acid

Answer 12

A substance that dissociates into one or more hydrogen ions and one or more anions
