The unknown acid H2X can be neutralized completely by OH according to the following (unbalanced) equation: H2X(aq)+ OH yields X^2-+ H2O The ion formed as a product, X2, was shown to have 36 total electrons. What is element X? Propose a name for H2X? To completely neutralize a sample of H2X, 35.6 mL of 0.175 M OH solution was required. What was the mass of the H2X sample used?
Critique the assumption that the exit streams are at equilibrium. Additional data: Henry's law constant for DMA at 25 °C is 1.84 bar.
estimate the relative permeability µr at a flux density of 1 T for M-19and AISI 1020 materials.
At 50 °C, 1.2 bar, the system n-pentane (1), n-hexane (2), and n-heptane (3) exists ion vapor-liquid equilibrium. The mole fractions in the two phases are: x1 = 0.6, x2 = 0.2, x3 = 0.2 in the liquid; and y1 = 0.87, y2 = 0.1, y3 = 0.03 ..
