Which characteristics of weak noncovalent interactions enable the assembly, stability, and functions of biomolecules? (pick one or more) A. They are readily reversible, whereas covalent bonds require a much larger input of energy to break.

B. They have a large cumulative effect, although individual interactions are relatively weak.

C. They are stable, requiring a large amount of energy to break.

D. They are not affected by the surrounding aqueous environment.

What are the variables in gay-lussac’s law? pressure and volume pressure, temperature, and volume pressure and temperature volume, temperature, and moles of gas

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
