What is the primary difference between a hypothesis and a theory?
a. a theory is supported by more data and observations than a hypothesis is.
b. a hypothesis is falsifiable, but a theory has been proven to be correct.
c. a theory is a prediction, but a hypothesis is an explanation.
d. a hypothesis is more reliable than a theory.

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)
