The distance (d) traveled by an automobile moving at an average speed of s is directly proportional to the time (t) spent travelling. The proportionality constant is the average speed. (1) Complete the symbolic expression of this relationship:(2) If it takes the automobile 2.09 hours to travel a distance of 153 miles, what is numerical value for the proportionality constant using the units given

Light waves travel than sound waves.

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)
