Question and Answer

• What is one of the greatest RPG series of all time?– (HINT)

ZELDA!

• Forms when a hydrogen atom covalently bonded to one electronegative atom is also attracted to another electronegative atom

Hydrogen Bonds

• Draw and label the main functional group found on Alcohols.

• Ethanol is an alcohol present in alcoholic beverages.

Functional Property: Is ethanol polar or non-polar?

• Ethanol is Polar as a result of the electrons spending more time near the electronegative oxygen atom.

What is the major component of all cell membranes?

Phospholipids

• Two atoms of an element that differ in number of neutrons are called?

Isotopes

• Chemical Properties of Isotopes of the same element are the– Same/Differ

• Physical Properties of Isotopes of the same element are the– Same/Differ

• Chemical Properties are the same• Physical Properties differ

• Whose Theory?– “all atoms of the same element had the same

weight, and elements differ from each other because they were composed of atoms of different weights”

• Dalton’s Theory, – John Dalton

• Draw the carbonyl functional group

• Draw a Ketone and an Aldehyde in a molecule with 3 Carbons.

• A chemical agent that increases the rate of a reaction without being consumed by the reaction

– This is a definition for?

• Catalyst

• What is the name of a macromolecule serving as a catalyst, a chemical agent that changes the rate of a reaction without being consumed by the reaction?

• Enzyme

• Draw an amino acid with 3 carbons AND circle and label the functional groups.

•Why is the Carboxyl group a source of hydrogen ions?

• Because the Covalent bond between oxygen and hydrogen is so polar

• The amino functional group acts as a base because?

• The Amino group acts as a base because it can pick up an H+ from the surrounding solution.
