Mrs. J. is a 31-year-old female admitted to the critical care unit with respiratory distress after getting the "flu." Her condition worsens; SpO2 is 85% on Venturi mask at 0.50. ABGs show a PaO2 of 50 mm Hg. Her chest x-ray is showing infiltrates. Calculate Mrs. J.’s PaO2/FiO2 ratio, and interpret the findings.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
