North of Kingston you discover a hidden mountain and name it Mt. Kevinmanjaro, which weighs 1x1012 kg and is made entirely of CaCO3(s) (MW = 100 g/mol, Ksp = 3.3×10–9). Each year the mountain received approximately 1×106 L of rainfall, which flow from the mountain completely saturated with Ca2+(aq). How many years will it take to entirely dissolve Mt. Kevinmanjaro?
In the analysis of H2O2 using KMnO4, the simulation first states that about 20 mL of water is added to the 1.00 mL aliquot of H2O2 to make the observation of the end point easier. Later, you are informed that your assistant diluted the 1.00 mL H2O2 sample to 10 mL with distilled water. Which of the following volumes is used in your analysis of the concentration of H2O2 in the original sample? Question 3 options: 10.00mL 20.00mL 11.00mL 21.00mL 1.00mL

The concentration of arsenic in an insecticide can be determined gravimetrically through its precipitation as MgNH4AsO4. After the formation of the precipitate, it must be ignited for total conversion to Mg2As2O7, which is then cooled and weighed. Considering that a sample of 1,627 g of the insecticide produced 106.5 mg of Mg2As2O7, determine the% (m/m) As2O3 in the insecticide. Given the molar masses: Mg2As2O7 = 310.447 g / mol and As2O3 = 197.841 g / mol
1. Mollie Cule prepared two solutions potassium chloride and barium chloride. However, she forgot to label the beakers. She has access to sodium sulfate, sodium phosphate, sodium hydroxide, and sodium bromide. How can Mollie Cule use her knowledge of solubility rules to determine which solution is in each beaker? Your answer should include expected results and how to interpret the results. 2. Polly and Ester are working with calcium fluoride (CaF2), which has a Ksp value of 4.0 x 10-11.

5. Adult oyster shells are composed mainly of calcite, CaCO3. It’s dissolution in water can be described as: CaCO3 (s) ⇌ Ca 2+ + CO32- The surface seawater around Hong Kong has concentrations of [CO32-] = 1 x 10-5 mol/kg and [Ca2+] = 0.01 mol/kg. Will oyster shells dissolve in the seawater?
To determine the percentage of bromide in a mixture containing a soluble bromide salt, the procedure from Experiment 10 is used except the bromide is precipitated with aqueous lead (II) nitrate, Pb(NO3)2, forming PbBr2(s). Initially, a 0.7893 g sample of an unknown bromide salt is dissolved in water. Excess Pb(NO3)2 is added to the solution to quantitatively precipitate the bromide from the solution. The resulting mixture is filtered through a piece of filter paper weighing 1.3587 g. After several days of drying, the filter paper and precipitate weighed 1.8257 g. Calculate the percent bromide in the original sample. Pb(NO3)2 Mw = 331.2 g/mol PbBr2 Mw = 367.0 g/mol
