"No matter what phase water is in, the water molecules stay the same; they just move differently." Explain why this evidence matters:

Sugar is dissolved in water. which is the solute? sugar neither both water

Is a pencil falling to the floor anon contact force, a force, or a contact force

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)
