<span>biological reactions that happen within cells while reducing the complex interactions found in a whole cell. Eukaryotic and prokaryotic cells have been used for creation of these simplified environments[1]. Subcellular fractions can be isolated by ultracentrifugation to provide molecular machinery that can be used in reactions in the absence of many of the other cellular components. Cell-free biosystems can be prepared by mixing a number of purified enzymes and coenzymes. Cell-free biosystems are proposed as a new low-cost biomanufacturing platform compared to microbial fermentation used for thousands of years. Cell-free biosystems have several advantages suitable in industrial applications</span>

Calculate the molecular mass of glucose
yan [13]
  • Glucose = C₆H₁₂O₆.
  • Atomic mass of C = 12 u
  • Atomic mass of H = 1 u
  • Atomic mass of O = 16 u
  • Therefore, the molecular mass of glucose
  • = (6 × Atomic mass of C) + (12 × Atomic mass of H) + (6 × Atomic mass of O)
  • = (6 × 12) + (12 × 1) + (6 × 16) u
  • = 72 + 12 + 96 u
  • = 180 u

Classify the substances according to the strongest solute-solvent interaction that will occur between the given substances and w
MArishka [77]

Answer:

A.  Dipole-dipole forces; B. dipole-dipole forces;

C. ion-dipole forces; D. ion-dipole forces

Explanation:

A. HF

HF is a weak acid but a highly polar molecule. The strongest intermolecular force with water is an especially strong dipole-dipole force (hydrogen bonding) of the type

H-F· · ·H-OH and H₂O· · ·H-F

B. CH₃OH

CH₃OH has a highly polar O-H bond. The strongest intermolecular force with water is the especially strong dipole-dipole force (hydrogen bonding):

CH₃(H)O· · ·H-OH and CH₃O-H· · ·OH₂

C. CaCl₂

CaCl₂(s) ⟶Ca²⁺(aq) + 2Cl⁻(aq)

CaCl₂ separates into hydrated ions in solution. The strongest intermolecular force with water is ion-dipole attraction.

Ca²⁺· · ·OH₂ and Cl⁻· · ·H-OH

D. FeBr₃

FeBr₃(s) ⟶Fe³⁺(aq) + 3Br⁻(aq)

FeBr₃ separates into hydrated ions in solution. The strongest intermolecular force with water is ion-dipole attraction.

Fe³⁺· · ·OH₂ and Br⁻· · ·H-OH
