druga drug has the initial concentration of 5.0 x 10-3g cm-3 in aqueous solution. after 24 months, the concentration drops to 3.48 x 10-3 g cm-3. this degradation process is known to follow first-order kinetics. which one of the following is the rate constant for this reaction?

no but i do not usually comment or use my voice that much when it comes to social media

the correct answer is:

a. formation of precipitation

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

answer: they produce more slow than unicellular organisms.
