MY CHEMISTRY ROMANCE - 100

What is the formula for the maximum number of electrons allowed in a

subshell?




ANSWERS

Maximum number of electronsIn a subshell = (4L + 2)


What is the ionization energy trend within the periodic table?




ANSWERS

Ionization energy increases as you move from left to right

across a period and up a group.


What is the formula for calculating formal charge on an atom involved

in a covalent bond?




ANSWERS

Formal Charge = V – (1/2 Nbonding + Nnonbonding),

Where V is the number of valence electrons of the atom in isolation (atom in ground state); Nnonbonding is the number of non-bonding valence electrons on this atom in the molecule; and Nbonding is the total number of electrons shared in covalent bonds with other atoms in the molecule.


What are the 3 types of intermolecular forces?




ANSWERS

Three Types of Intermolecular Forces:1. Dipole-Dipole Interaction

2. Hydrogen Bonding3. Dispersion Forces


What are the following types of reactions?

1. A + X AX2. AX + B BX + A

3. AX + BY AY + BX




ANSWERS

The following types of reactions are:1. A + X AX = Addition2. AX + B BX + A = Single Displacement3. AX + BY AY + BX = Double

Displacement

LAWS ACCORDING TO EINSTEIN - 100All of the following are true of both magnetism &

electricity EXCEPT:a. Like poles & charges repel; opposites attract.

b. The strength of attraction & repulsion of electric charges or magnetic poles vary inversely as the square of the distance between the charges or poles.

c. It is possible to isolate a single positive or negative electric charge or a single north or south magnetic pole.

d. The forces of attraction or repulsion between two magnetic poles on either pole, or between two electric charges on either charge are of equal strength.


LAWS ACCORDING TO EINSTEIN - 100


ANSWERS

CMagnetism differs from electricity in that

a single positive or negative electron charge can be isolated, but magnetic

poles cannot

LAWS ACCORDING TO EINSTEIN - 200In which direction will a compass point

if it is held directly over a wire carrying a strong current?

a. Northb. Southc. Perpendicular to the wired. Parallel to the wire


ANSWERS

CThe magnetic field created by the wire

will go around the wire. The north pole of the compass magnetic field will point against this magnetic field.

THE PERFECT PAIR OF GENES - 100

Define the difference between phenotype and genotype.



THE PERFECT PAIR OF GENES - 100ANSWERS

Genotype refers to the genetic makeup of an individual.

Phenotype refers to the physical manifestation

of an individual’s genotype.


Summarize Mendel’s First Law (Law of Segregation)




Mendel’s first law states that alleles segregate during meiosis; specifically:

1. Genes exist in alternative forms (alleles).2. An individual inherits 2 alleles for each trait,

one from each parent.3. The 2 alleles segregate during meiosis.

4. If 2 different alleles are present, only 1 will be fully expressed.


There are flowers with a specific characteristics:

Given: P = Dominant (Purple) p = recessive (White)

What is genotypic ratio of Pp x pp cross?




Pp x pp50% Pp : 50% pp


What is the percentage for daughters to inherit their father’s sex-linked gene?




100% of daughters will inherit their father’s sex-linked genes.


What are the 3 differentresults of chromosomal breakage?




The three different results of chromosomal breakage:

1. Duplication: the fragment joins with its homologous chromosome.

2. Translocation: The fragment joins with a non-homologous chromosome.

3. Inversion: The fragment rejoins its original chromosome but in the reverse position.

ANSWERS




1. Are these D or L amino acids? Why?

a. b.

2. TRUE or FALSE: The alpha carbon is chiral in all amino

acids.

3. What is a Zwitterion?


ANSWERS1- a. D amino acid = Amino group on the

Right b. L amino acid = Amino group on the

Left

2- FALSE, glycine’s alpha carbon has 2 hydrogens and is therefore not chiral.

3- A Zwitterion is a species with both positive and negative charge.
