  2. MY CHEMISTRY ROMANCE - 100 What is the formula for the maximum number of electrons allowed in a subshell? Medical Pathway Program 7

  3. MY CHEMISTRY ROMANCE - 100 • ANSWERS Maximum number of electrons In a subshell = (4L + 2) Medical Pathway Program 7

  4. MY CHEMISTRY ROMANCE - 200 What is the ionization energy trend within the periodic table? Medical Pathway Program 7

  5. MY CHEMISTRY ROMANCE - 200 • ANSWERS Ionization energy increases as you move from left to right across a period and up a group. Medical Pathway Program 7

  6. MY CHEMISTRY ROMANCE - 300 What is the formula for calculating formal charge on an atom involved in a covalent bond? Medical Pathway Program 7

  7. MY CHEMISTRY ROMANCE - 300 • 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. Medical Pathway Program 7

  8. MY CHEMISTRY ROMANCE - 400 What are the 3 types of intermolecular forces? Medical Pathway Program 7

  9. MY CHEMISTRY ROMANCE - 400 • ANSWERS Three Types of Intermolecular Forces: • Dipole-Dipole Interaction • Hydrogen Bonding • Dispersion Forces Medical Pathway Program 7

  10. MY CHEMISTRY ROMANCE - 500 What are the following types of reactions? • A + X  AX • AX + B  BX + A • AX + BY  AY + BX Medical Pathway Program 7

  11. MY CHEMISTRY ROMANCE - 500 • ANSWERS • The following types of reactions are: • A + X  AX = Addition • AX + B  BX + A = Single Displacement • AX + BY  AY + BX = Double Displacement Medical Pathway Program 7

  12. LAWS ACCORDING TO EINSTEIN - 100 All of the following are true of both magnetism & electricity EXCEPT: • Like poles & charges repel; opposites attract. • The strength of attraction & repulsion of electric charges or magnetic poles vary inversely as the square of the distance between the charges or poles. • It is possible to isolate a single positive or negative electric charge or a single north or south magnetic pole. • 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. Medical Pathway Program 7

  13. LAWS ACCORDING TO EINSTEIN - 100 • ANSWERS • C • Magnetism differs from electricity in that a single positive or negative electron charge can be isolated, but magnetic poles cannot Medical Pathway Program 7

  14. LAWS ACCORDING TO EINSTEIN - 200 In which direction will a compass point if it is held directly over a wire carrying a strong current? • North • South • Perpendicular to the wire • Parallel to the wire Medical Pathway Program 7

  15. LAWS ACCORDING TO EINSTEIN - 200 • ANSWERS • C • The 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. Medical Pathway Program 7

  17. LAWS ACCORDING TO EINSTEIN - 300 • ANSWERS Medical Pathway Program 7

  18. LAWS ACCORDING TO EINSTEIN - 400 Medical Pathway Program 7

  19. LAWS ACCORDING TO EINSTEIN - 400 • ANSWERS Medical Pathway Program 7

  20. LAWS ACCORDING TO EINSTEIN - 500 CIRCUITS BELOW HAVE BATTERIES WHICH ALL HAVE THE SAME EMF • A) X • B)Y • C) Z • D) All the above • are equal 1.Which Circuit has the greatest current? 2.Which of the following provides the most current? 3. Which circuit provides the least light? Medical Pathway Program 7

  21. LAWS ACCORDING TO EINSTEIN - 500 • ANSWERS • C • C • B Medical Pathway Program 7

  22. THE PERFECT PAIR OF GENES - 100 Define the difference between phenotype and genotype. Medical Pathway Program 7

  23. THE PERFECT PAIR OF GENES - 100 ANSWERS Genotype refers to the genetic makeup of an individual. Phenotype refers to the physical manifestation of an individual’s genotype. Medical Pathway Program 7

  24. THE PERFECT PAIR OF GENES - 200 Summarize Mendel’s First Law (Law of Segregation) Medical Pathway Program 7

  25. THE PERFECT PAIR OF GENES - 200 ANSWERS Mendel’s first law states that alleles segregate during meiosis; specifically: • Genes exist in alternative forms (alleles). • An individual inherits 2 alleles for each trait, one from each parent. • The 2 alleles segregate during meiosis. • If 2 different alleles are present, only 1 will be fully expressed. Medical Pathway Program 7

  26. THE PERFECT PAIR OF GENES - 300 There are flowers with a specific characteristics: Given: P = Dominant (Purple) p = recessive (White) What is genotypic ratio of Pp x pp cross? Medical Pathway Program 7

  27. THE PERFECT PAIR OF GENES - 300 ANSWERS Pp x pp • 50% Pp : 50% pp Medical Pathway Program 7

  28. THE PERFECT PAIR OF GENES - 400 What is the percentage for daughters to inherit their father’s sex-linked gene? Medical Pathway Program 7

  29. THE PERFECT PAIR OF GENES - 400 ANSWERS 100% of daughters will inherit their father’s sex-linked genes. Medical Pathway Program 7

  30. THE PERFECT PAIR OF GENES - 500 What are the 3 different results of chromosomal breakage? Medical Pathway Program 7

  31. THE PERFECT PAIR OF GENES - 500 ANSWERS • The three different results of chromosomal breakage: • Duplication: the fragment joins with its homologous chromosome. • Translocation: The fragment joins with a non-homologous chromosome. • Inversion: The fragment rejoins its original chromosome but in the reverse position.
