14.64 mL of 0.446 M K2SO3 is diluted to 59.95 mL, and 12.84mL of this solution us diluted to 49.95mL. New molarity?​

The number to the right of an element's symbol (ex. c-12) identifies the of an isotope.

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)

If energy was included in a chemical reaction, on which side of the equation would it be written for an endothermic reaction?
