Separating a mixture of two liquids into its components based on their boiling points is known as:

Which part of earth’s surface receives the most direct rays from the sun? a) equator b) ocean c) poles d) mountains

Consider this initial-rate data at a certain temperature for the reaction described by

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)
