Kidney stones are crystals of calcium oxalate that form in the kidney, ureter, or bladder. Small kidney stones are passed out of the body easily, but larger kidney stones may block the ureter causing SEVERE pain. If the [Ca^+2] in blood plasma is 3.2 x 10^(-2)M, what [C2O4^-2] must be present to form a kidney stone? Ksp = 2.3 x 10^(-9) x 10(-8)M (to the proper significant figures)

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
