Formalin is 37% (density of 815 kg/m3) aqueous solution of formaldehyde (HCOH). Formalin is used as a preservative of biological specimens. C is bold.
a) What is the molarity of formalin in micromole/microliter?
b) Give the following for (HCOH): electron geometry, hybridization, and
intramolecular forces (all)

A glucose solution of viscosity 2.2 × 10−3 N⋅s/m2 and density 1030 kg/m3 flows from an elevated open bag into a vein. The needle into the vein has a radius of 0.20 mm and is 3.0 cm long. All other tubes leading to the needle have much larger radii, and viscous forces in them can be ignored. The pressure in the vein is 1000 N/m2 above atmospheric pressure. Determine the pressure relative to atmospheric pressure needed at the entrance of...
