Jane starts driving her car down the road at 30 miles per hour. at the same time, the local train starts going down the tracks. the train is going 35 miles per hour, a little bit faster than jane's car. after two hours, which will cover the greater distance, the train or the car? a) the car. b) the train. c) the distance they cover will be the same. d) who travels further is impossible to say.

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)
