A 4.50 g sample of limestone (impure CaCO3) was dissolved in 0.1M HCl solution according to the following equation. CaCO3(s) + 2HCl(aq) → CaCl2 (aq) + CO2 (g) + H2O (l) Excess of (NH4)2C2O4(aq), was added to the resulting solution to precipitate the calcium ions as calcium oxalate, CaC2O4(s). Ca2+(aq) + C2O42-(aq) → CaC2O4 (s) The precipitate was filtered, dried and weighed at 2.15 g. (Show your work) a) Determine the percentage by mass of calcium carbonate (CaCO3) in the limestone sample. (MM of CaCO3 is 100.09 g/mol) b) Why we need to dry the precipitate until we get a constant mass? c) Is the precipitate of calcium oxalate (CaC2O4) stable and in the final form or not? Explain.

The following reaction occurs when two aqueous solutions are mixed: Cr(NO3)3(aq) + 3NaOH(aq) → Cr(OH)3(s) + 2NaNO3(aq) Identify the spectator ion OR ions in the solution. SELECT ALL SPECTATOR IONS!
Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCI through this reaction: HCl(aq) + NaHCO3(aq) NaCl(aq) + H₂O(l) + CO₂(9) The CO2 gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 200. mL of a 0.027 M HCl solution. What mass of NaHCO3 would he need to ingest to neutralize this much HCI ? Round your answer to 2 significant digits. X 5

Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HC1), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HC1 through this reaction: HCl(aq) + NaHCO3(aq) NaCl(aq) + H₂O(1) + CO₂(g) The CO₂ gas produced is what makes you burp after drinking the solution.
