Remarkably, a catalytic system that uses light energy to hydrolyze water into hydrogen h2(g) and o(g) has been devised (science 334, 2011: 645-648) to capture and efficiently store solar energy. hydrogen is "clean burning" in that it yields only h2o. in this problem you will contrast the combustion of 1 kgh2(g) to that of 1 kg of n-octane.

Temperature and kinetic energy are proportional. a) adirectly b) directly c) indirectly

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)

What is the indicator of the number of ions in solution? the amount of conductivity the amount of precipitate the amount of solute added
