1.Write equations for the neutralization reactions that result in the formation of the following salts:
a) lithium carbonate
b) copper (II) chlorate
c) aluminum sulphate
d) ammonium iodide
2.For each of the following situations, identify those for which a reaction is likely to occur. For those that do occur, write a net ionic equation.
a) Chromium dipped into silver nitrate.
b) Gold immersed in hydrochloric acid.
c) Nickel pellets dropped into calcium acetate, Ca(C2H3O2)2.
d) Aluminum dropped into a bath of sulphuric acid.
e) Zinc dipped into a solution of lead (II) nitrate.
3.An industrial plant that specializes in cleaning up waste liquids is confronted with a problem of separating the metal ions found in a large vat of solution. By analysis, the solution was found to contain varying quantities of silver, barium, and iron (III) ions. Suggest a procedure for separating the metal ions be precipitation.
4. A chemist wishes to prepare 200mL of a saturated solution of BaF2, the concentration of which is 6.3 x 10-3 mol/L. Determine the mass of BaF2 that will be needed to make up the 200mL of the solution.© BrainMass Inc. brainmass.com October 24, 2018, 9:09 pm ad1c9bdddf
This solution answers several descriptive chemistry questions, addressing equations for neutralization reactions, net ionic equations, and separating metal ions.
Exemplify Quantitive Data.
In contrast to the qualitative paradigm, quantitative data is used to answer specific research questions with the aid of statistical analysis. Identify and discuss at least three non-experimental research methods. Define and explain the type of data that would be used in each of your chosen methods.View Full Posting Details
