19. Identify the ions present in a crystal of Na2SO4. A. B C Na*, S2", and O2 Na, S2, and o Na*, s2, and 0-2 Na and S04-2 Na* and S04 D. E. I 20. Why are many ionic compounds not soluble in water? A. They are non-polar and do not mix well with H20 B. They have metals that are much denser than water C. They have high charge density which makes stronger ionic bonds that water can't break...
1. Animal cells have a Na,K pump that couples the energy of ATP hydrolysis to transport 3 Na ions out of the cell and 2 K ions into the cell. Inside astrocytes, the concentration of Na is 20 mM and the concentration of K is 130 mM. The extracellular concentrations of Na and K are 145 mM and 5 mM, respectively. Calculate the energy required for the transport of Na and K , with this stoichiometry; assume that the cell...
