A rigid, closed vessel of volume V =648 liters maintained at constant temperature T=365 K is loaded with 112 mol of n-hexane, 155 mol of n-heptane, and 14 mol of nitrogen. Calculate the pressure in the vessel and the composition of all phases present at equilibrium. Make the following three assumptions: a) n-hexane and n-heptane form an ideal liquid solution, b) the vapor phase is ideal, c) nitrogen has negligible solubility in the liquid phase at the conditions of interest. The vapor pressures of n-hexane and n-heptane at T=365 K are P1=0.199 MPa and P2=0.083 MPa, respectively. Their (liquid) molar volumes are V¯ 1=0.146 l/mol and V¯ 1=0.162 l/mol, respectively.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.

The twister and runaway train are two coasters at the same amusement park. both coasters start at the same height. the coaster for the twister is twice the mass of the coaster for the runaway train. which roller coaster has greater gravitational potential energy at the start of the ride?
