Dr. broncho used an afm system with a spherical indenter tip (diameter 0.8 um) to probe the stiffness of the cultured mesenchymal stem cells. he measured a cell indentation of 0.08 jum under the quasi-static load of 80 pn. assume the poisson's ratio for these cells are 0.45 (a) estimate the young's modulus of these stem cells. (b) dr. broncho then treated these cells with cytochalasin d and did the similar afm test again, he found that only 28-pn load was needed to cause 0.08 am indentation on the treated cells. dr. broncho determine the young's modulus of the treated cells. briefly describe why this result is quite different compared with the value for untreated cells. (c) if dr. broncho wants these cells to become osteoblast-like cells after culture, what would be the magnitude of the elasticity of the substrate he needs to use? why?

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
