Write balanced, net ionic equations for the following precipitation, acid-base, or gas-forming reactions. include states of matter. hint: you should write the molecular equation first to predict the products. a) mixing aqueous solutions of iron (iii) chloride and sodium sulfide b) mixing aqueous solutions of sodium nitrate and ammonium phosphate c) mixing aqueous solutions of perchloric acid and lithium hydroxide d) mixing aqueous solutions of ammonia and nitric acid e) mixing aqueous solutions of nitrous acid and sodium hydroxide f) adding aqueous hydrobromic acid to solid calcium carbonate g) problems c) through f) are acid- base reactions. comment on the differences in the net ionic equations for these reactions

Consider the equilibrium system: 2icl(s) ⇄ i2(s) + cl2(g) which of the following changes will increase the total amount of of cl2 that can be produced? all of the listed answers are correct decreasing the volume of the container removing the cl2 as it is formed adding more icl(s) removing some of the i2(s)

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.

Why is the structure of molecule important to its function?
