B. Ionic bond
C. Covalent bond
D. Non polar bond
Answer: B
Rationalization: Ionic bond - valence electron(s) is/are completely transferred between atoms, a metal (Sodium cation) and nonmetal (Fluoride anion).
It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion
32. You won the jackpot prize in the lottery. The prize money cannot be paid in currency but only in gold. Applying your knowledge in chemistry, select the largest amount of gold from the choices below (Au=197).
A. 297 g of gold
B.40 kg of gold
C. Avogadro's number of an atom of gold
D. 22.4 moles of gold
Answer: B
Rationalization: To idetinfy the largest amount of gold, the number of atoms of gold must be calculated. Using the Avogadro’s number (number of particular atoms per mole)
40 kg= 1.22x10E26
Calculation: No. of Au atoms = (40 kg x 1000g/kg) (1 mol/197g) x 6.02x10E23 atoms/mol = 1.22x10E26
You can calculate other given using the formula above. It will result lesser number of Au atoms.

C. Autolysis and Photosynthesis
D. Autolysis and Putrefaction
Answer: D
Rationalization: Decomposition begins at the moment of death, caused by two factors: 1.) autolysis, the breaking down of tissues by the body's own internal chemicals and enzymes, and 2.) putrefaction, the breakdown of tissues by bacteria.
