Experiment 1: floating ice for this experiment, you will need a permanent marker, a translucent plastic cup, water, and ice. place a few ice cubes in the cup, and add water until the ice cubes float (that is, they don’t touch the bottom). mark the water level on the outside of the cup with the marker, and label this mark so that later you will know it was the initial water level. as the ice melts, what do you expect to happen to the water level in the cup? html editor keyboard shortcuts

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.
