How does fluorine's atomic radius compared to oxygen's radius and chlorine's

yanalaym [24]

Answer:

F < O < Cl

Explanation:

Fluorine has a greater effective nuclear charge than oxygen does, meaning that the electrons are drawn tighter and closer toward the nucleus. Fluorine has 9 protons and 9 electrons while oxygen only has 8 protons and electrons. Chlorine has a larger atomic radius than both fluorine and chlorine because has another energy level (shell). Although chlorine has the same effective nuclear charge as fluorine, chlorine has more electrons, 17, which requires an additional shell to contain them.

An animal cell placed in a hypertonic solution will shrink in a process called crenation. An animal cell placed in a hypotonic s

tresset_1 [31]

Answer:

Solution A: 3.21% (m/v) NaCl ⇒ CRENATION

Solution B: 1.65% (m/v) glucose ⇒ HEMOLYSIS

Solution C: distilled H₂O ⇒ HEMOLYSIS

Solution D: 6.97% (m/v) glucose ⇒ CRENATION

Solution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl ⇒ CRENATION

Explanation:

Isotonic solution = 0.9% (m/v) NaCl or 5.0% (m/v) glucose

Crenation will occur if the solution has a concentration higher than 0.9% (m/v) NaCl or 5.0% (m/v) glucose (hypertonic solution). This will occur in the following solutions:

Solution A: 3.21% (m/v) NaCl > 0.9% (m/v) NaCl

Solution D: 6.97% (m/v) glucose > 5.0% (m/v) glucose

Solution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl (the addition of the 2 components exceeds the osmotic pressure permitted).

Hemolysis will occur if the solution has a concentration lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose (hypotonic solution). This is the case of:

Solution B: 1.65% (m/v) glucose < 5.0% (m/v) glucose

Solution C: distilled H₂O = 0% glucose/0% NaCl < 0.9% (m/v) NaCl or 5.0% (m/v) glucose
