Neutrons – 16

Electrons - 15

4

Define the octet rule.

How many valence electrons does Chlorine (Cl) have? According to the octet rule, how many covalent bonds will Cl form?

5

Octet Rule = atoms tend to gain, lose or share electrons so as to have 8 electrons

Cl has 7 valence electrons, so it will form 1 covalent bond.

7

1.Ionic

2.Non-polar covalent

3.Polar covalent

4.Polar covalent

Draw a molecule of N2, showing all electrons in their appropriate levels. What type of bond is found in this molecule?

17

A triple covalent bond (6 shared electrons)

18

Water is a polar molecule. Explain this statement. Describe how water is able to dissolve salts such as NaCl.

19 Water has a positive and a negative pole. The positive (hydrogen) end surrounds and attracts negative Cl- ions. The negative (oxygen) end attracts and surrounds positive Na+ ions.

What is an acid?

What is a base?

What is a buffer?

21

An acid – gives of hydrogen (H+) ions in solution. Ex: HCl

A base – gives off hydroxide (OH-) ions in solution. Ex: NaOH

A buffer – helps resist pH change

31Monomer Polymer

Monosaccharide Polysaccharide

Nucleotide Nucleic Acid

Amino Acid Protein

Lipids are not polymers because they are not made of repeating subunits. Fat is composed of 1 glycerol and 3 fatty acids.

32

Give 2 examples of lipids, and 2 examples of nucleic acids.

33

Lipids: triglycerides (fats and oils), waxes, steroids, phospholipids

Nucleic Acids: DNA, RNA

34

DNA is a polymer consisting of repeating units known as _____.

There are 4 of these… name them.

35

What are nucleotides?

A - Adenine, C - Cytosine, G - Guanine, T - Thymine

36 Use the following words to completely describe the structure of a DNA molecule:

Sugar/phosphate

Nucleotide

Nitrogenous base

Hydrogen bond

Double helix

37 DNA is 2 long chains of nucleotides, twisted together in a double helix. Each chain consists of a sugar/phosphate backbone, and nitrogenous bases. The 2 strands of DNA are held together by hydrogen bonds between the nitrogenous bases.

38

Describe the parts of the molecules above in terms of being hydrophobic and hydrophilic.

What type of lipids are represented in this picture?

39

What are phospholipids?

Non-polar (hydrophobic) fatty acid tail

Polar (hydrophilic) head

40

DNA codes for traits in organisms. Specifically describe how a molecule of DNA is translated into an organism’s traits.

41DNA codes for proteins. Sequence of nucleotide bases determines the sequence of amino acids in the polypeptide chain. Sequence of a.a. determines protein folding and shape, which determines function.

42

Movement of water molecules from areas of high concentration to areas of low concentration.

43

What is osmosis?

44

The point at which molecules are evenly distributed, and diffusion stops.

45

What is equilibrium?

46

2 Factors that affect the rate of diffusion.

47

What is temperature, pressure, concentration.
