A rectangle block of height L and horizontal cross-section area A floats at the interface between two immiscible liquids.
(a) Derive a formula for the block density, pb, in terms of the fluid densities p1 and p2, the height h0, h1, and h2, and the cross-sectional area A. (It's not necessary that all of these variables appear in the final result.)
(b) Force balances on the block can be calculated in two ways: (1) in terms of the weight of the block and the hydrostatic forces on the upper and lower block surfaces; and (2) in terms of the weight of the block and the buoyant force on the block as expressed by Archimedes' principle. Prove that these two approaches are equivalent.
You titrate 25.0 mL of 0.110 M NH3 (Kb = 1.76 x 10-5) with 0.100 M HCl. What volume of HCl is required to reach the equivalence point and what is the pH at the equivalence point
A student added 2.33g Phenyl Propane, 2.73g Sodium bromide, and 5ml of Sulfuric acid (along with boiling chips). The solution was refluxed for 45 min and distilled. What happened during this reaction
Rank SCl2, PCl3, and SiCl4 in order of increasing ionic character of their bonds. Use polar arrows to indicate the bond polarity of each bond.
Consider all the valence electron pairs of the central atom-both those that are shared in covalent bonds, called bonding pairs, and those that are unshared, called non-bonding pairs or unshared pairs.
