Can someone . a sucrose solution is prepared to a final concentration of 0.170m . convert this value into terms of g/l, molality, and mass % (molecular weight, mwsucrose = 342.296g/mol ; density, ρsol′n = 1.02g/ml ; mass of water, mwat = 961.8g ). note that the mass of solute is included in the density of the solution,

Draw the lewis dot structure for each of the following polyatomic ions

Alidded glass container is filled with a colored gas. after a period of time, it is observed that the gas is uniformly spread throughout the box and that the movement has slowed considerably. next, a warm iron plate is carefully placed under the box. why is there resumed movement of the gas in the container?

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
