In a student experiment, the empirical formula of a copper halide was found by adding aluminum metal to an aqueous solution of the halide, displacing copper metal. The copper metal was filtered, washed with distilled water, dried, and weighed; three separate determinations were performed. The copper halide solution contained 42.62 of copper chloride per liter. The student recorded the following experimental data
Trial A) 49.6 ml of copper chloride solution and weight of copper is .786gTrial B)48.3 ml of copper chloride in solution and weight of copper is .771gTrail C)42.2 ml of copper chloride in solution and weight of copper is .669gWhat is the empirical formula of copper chloride based on the experimental data?
What is the minimum concentration of ammonia that should dissolve AgBr to produce a 0.01 M Ag(NH3)2+ solution
find the density and specific volume of air over the range of normal room conditions. take barometric pressure to vary
theoretically feasible in a solution that initially 0.250 M in each ion? c.) If separation is feasibe in eithee (a) or (b), what ranfe of anode potential (vs. SCE) should be used?
Yet the stock bottle clearly reads 0.0020 M. Why? Similarly, why is the initial concentration of iron (III) ion 0.10 M when the stock bottle contained 0.20 M iron (III) nitrate?
A 0.831-g sample of SO3 is placed in a 1.00-L container and heated to 1100 K. The SO3 decomposes to SO2 and O2: 2SO3(g) 2SO2(g) + O2(g). At equilibrium the total pressure in the container is 1.300 atm. Calculate Kp for the above reaction at 1100..
