Experiment 5 Prelaboratory Assignment Percent Water in a Hydrated Salt chloride, a deliquescent salt, is used as a desiccant in laboratory desiccators to maintain a dry environment Date ab SecName Desk No. Explain. 1sb 2. Experimental Procedure, Part A.1. What is the purpose of firing the crucible? 3. A 1.803-g sample of gypsum, a hydrated salt of calcium sulfate, Caso., is heated at a temperature greater than 120 C in a crucible until a constant mass is reached. The mass...
Would CuCO3 aqueous salt combined with calcium chloride form a solid precipitate? If so, what would the precipitate be? Show your work.
Calcium Fluoride Determine the number of calcium ions per unit cell. Determine the number of fluoride ions per unit cell. What is the empirical formula of calcium fluoride based on the relative number of each ion in the unit cells? Is the empirical formula determined from the lattice structure in agreement with the one predicted by the typical ion charges? Are the anions or cations arranged in one of the basic cubic unit cells (simple, body-centered, face-centered)?

Sodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water by calculating the freezing point depression of solutions containing 230. g of each salt in 1.00 kg of water. (An advantage of CaCl2 is that it acts more quickly because it is hygroscopic, that is, it absorbs...
Magnesium chloride, MgCl2, is a common roadway deicer salt. calculate the weight percent of the chloride in the salt. show your work.
How many grams of calcium chloride were used if 2.872 grams of calcium oxalate monohydrate were produced, assuming a 100% yield. This means all of the calcium chloride was converted to calcium oxalate monohydrate. Report your answer to 3 decimal places in grams
Part 4. Molality of the calcium chloride solution Molality is defined as mol solute Calculate the molality of your assigned calcium chloride solution. Assume that the density of kg solvent water is 1g/mL. Questions (SHOW ALL WORK) 1. Calculate the molarity (M) of a solution when 12.80 g of glycerol (CHsOs) is added to 40.70 g of water. The density of the solution is 1,052g/ml Colligative properties like boiling point elevation depend on the number of solute particles in solution....
Calculate the following: a.) The molar concentration of calcium ions and carbonate ions in pure water. b.) The molar solubility of calcium carbonate in pure water. c.) The mass, in mg, of calcium carbonate (MM = 100 g/mol) you would need to dissolve in 1 L of pure water to make a saturated solution.
How many grams of calcium chloride were used if 2.512 grams of calcium oxalate monohydrate were produced, assuming a 100% yield. This means all of the calcium chloride was converted to calcium oxalate monohydrate. Report your answer to 3 decimal places in grams.
