Calculate the standard cell emf for the reaction ClO3−(aq) + 3Cu(s) + 6H+(aq) → Cl−(aq) + 3Cu2+(aq) + 3H2O(l)

Pt is used as an inert electrode in contact with the ClO3− and Cl−.

Calculate the standard emf using data in Appendix E and given the following:

ClO3−(aq) + 6H+(aq) + 6e−→Cl−(aq) + 3H2O(l); E∘=1.45 V

Express the emf to two decimal places with the appropriate units.

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)

8) warming your hands by a fire is an example if which heat transfer? a. conduction b. convection c. radiation d. none of these

An experiment is conducted to see if cats preferred skim milk or 2% milk. a cup of skim milkwas put out for 5 kittens and then measured how much the kittens drank over the course of aday. following a cup of 2% milk was purout for the skittens and then masured how much thekittens drank over the course of a day. the same kittens were used and the milk was served atthe same temperature. it was discovered that the cats liked the 2% milk more than the skimmilk. what is the dependent variable in this experiment?
