Question
Which of the following properties of water make(s) life possible? (A) Water has strong hydrogen bonding interaction between molecules, which allow is to exist at ambient temperature as a liquid. (B) Water's high dielectric constant allows it to dissolve polar and charged molecules alike. (C) Water is less dense as a solid than as a liquid. (D) Water has strongly hydrogen bonding interaction between molecules, which allow it to have a high heat evaporation. (E) All of the listed properties of water make life possible. Aspartic acid is a weak amino acid, its structure is shown below. 10(60) Draw a possible titration curve (pH versus [OH^-]) for 1 M aspartic solution. Indicate the pKa s in the graph (pK1 =
Explanation / Answer
15. Properties of water molecules that make life possible is,
(E)
Water is a unique polar, lower density than ice, remains liquid at room temperature.
All these properties support life on earth.
