SOLVED:A 1.248-g sample of limestone rock is pulverized and then treated with 30.00 mL of 1.035 M HCl solution. The excess acid then requires 11.56 mL of 1.010 M NaOH for neutralization. Calculate the percentage by mass of calcium carbonate in the rock, assuming that it is the only substance reacting with the HCl solution.

SOLVED: A 2.634 g limestone rock sample (containing CaCO3)was first treated with an excess of concentrated HCl. Then oxalicacid was added to form calcium oxalate precipitate. The precipitatewas filtered off, dried, and annealed. During annealing of theprecipitate the calcium oxalate was transformed into stable calciumoxide, which had a mass of 1.325 g.Write for each step of the gravimetric analysis of thelimestone rock, an appropriate balanced reaction equation: (i)including sample preparation (

SOLVED: Many ancient tombs were cut from limestone rock that contained uranium. Since most such tombs are not well-ventilated, they may contain radon gas. In one study, the radon levels in a sample of 12 tombs in a particular region were measured in becquerels per cubic meter (Bq/m^3). For this data, assume that x = 3,778 Bq/m^3 and s = 1,294 Bq/m^3. Use this information to estimate, with 95% confidence, the true mean level of radon exposure in tombs in the region. Interpret the resulting interv
