Question 1. According to Kate, what is the secret of perfect popcorn popping?
Quesiton 2. After 1.00 ml of water is completely vaporized to gas, how many milliliters of vapor are produced at standard temperature and pressure? (Density of water is 1.00 g/mL; molar volume of any gas at STP is 22.4 L/mol.)
Quesiton 3. Write the equation for the formation of maltose, a disaccharide, which consists of two glucose units. Classify the reaction.
Quesiton 4. How many water molecules are needed to break down an oligosaccharide that contains 10 glucose units? Classify the reaction.
Quesiton 5. Write and balance the cellular respiration equation of glucose (C6H12O6). Compare it with the photosynthesis reaction in terms of reactants, products, energy l ow, and the signii cance of each.
Quesiton 6. Glycerol, a part of glycerophospholipid, is highly attracted to water and often used in skin care products such as lotions and cosmetics. Draw the structure of glycerol. Explain its attraction to water and describe the interaction of glycerol with water.
