The S I units should be explained given the measurements of mass, volume, length and temperature. Concept Introduction: Physical quantity: It can quantified that is can be measured using numbers, for example physical quantities are mass, amount of substance, length, time, temperature, electric current , light intensity, force, velocity, density and others. Measurements: There are seven base unites in the S I system, kilogram ( ( k g ) for mass, second ( s ) for time, kelvin ( K ) for temperature, ampere ( A ) for electric current, mole ( m o l ) amount of the substance, candle ( c d ) for luminous intensity and meter ( m ) for distance.

Consider a system consisting of an egg in an incubator. The white and yolk of the egg contain proteins, carbohydrates, and lipids. If fertilized, the egg transforms from a single cell to a complex organism. How does the entropy change in both the system (developing chick) and suroundings (the egg environment) drive the irreversible process of chick development? ☐ The release of glucose from sucrose, which produces energy needed for chick development, decreases entropy in the surroundings. Chick development increases entropy in the system, which causes a concominant decrease in entropy in the surroundings. Carbohydrates, proteins, and lipids within the egg break down into CO2 and H2O, which increases entropy in the surroundings. Chick development decreases entropy in the system, but this is smaller than the concominant increase in entropy in the surroundings.

The amino acid glycine is often used as the main ingredient of a buffer in biochemical experiments. The amino group of glycine, which has a pKa of 9.6, can exist either in the protonated form -NH or as the free base -NH2, because of the reversible equilibrium R-NH =R-NH₂ + H+ In what pH range can glycine be used as an effective buffer due to its amino group? pH 8.6 to pH 10.6 In a 0.1 M solution of glycine at pH 9.0, what fraction of glycine has its amino group in the -NH form? Correct Answer Correct Answer 45 How much 5 M KOH must be added to 1.0 L of 0.1 M glycine at pH 9.0 to bring its pH to 10.0? 10 mL When 99% of the glycine is in its -NH form, what is the numerical relation between the pH of the solution and the pKa of the amino group? pH = pKa - 2 Correct Answer Correct Answer
