Question

4,5&6 A graph of mass % sugar versus density of solution produces a linear line with a positive slope. The equation of the line is y 0.0045x + 0.997. What is the mass% of sugar in a solution that has a density of 1.022 g/mL? Separate the components of water-insoluble mixture of barium sulfate (BaSO_4) and nickel (II) carbonate (NiCO_3). Chemicals provided to aid in the separation and recovery of the 2 component mixtures are HCl_(aq) and K_2CO_3(aq). Provide a balanced chemical equation for each reaction that is performed and write an explanation for each step. The physical and chemical properties are given below. An aluminum wire is dipped in a solution containing sodium, tin, and copper ions. Which ions will be present in solution after the reaction is complete? FULLY EXPLAIN YOUR ANSWER. Refer to the activity series in your text to answer.

Explanation / Answer

y= 0.0045x + 0.997

where y represent mass% and x represent density.

Calculate the value of y when x = 1.022gm/mL

y = 0.0045 * 1.022 + 0.997 = 1.002%

mass % of sugar = 1.002%
