Sodium hydrogen carbonate (NaHCO, ), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acıd ihdlgestloH burning sensation of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: you get in your stomach when it contains too much hydrochloric acid (HCI) , which the stomach secretes to help digest food. Drinking a glass HCl(aq) + NAHCO,(aq) → NaCl(aq) + H,O(1) + C0,(g) The CO, gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 200. mL of a 0.035 M HCI solution. What mass of NaHCO, olo would she need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits. Ar

The solubility of Mg(OH), in water at 25 °C is measured to be 0.0096 . Use this information to calculate K, for Mg(OH),. sp Round your answer to 2 significant digits.

For the denitrification [microbiological conversion of nitrite/nitrate (N-containing contaminants) to nitrogen gas (harmless end product)] to be more effective, an external carbon source (e.g., methanol) is frequently added for denitrifiers (denitrifying microorganisms) during the reaction. The following chemical reaction is for when methanol is added for this purpose. Calculate how much (concentration) of methanol (in mg/L) needs to be added to completely convert 30 mg/L of NO3--N to N2 gas. 0.1667 CH3OH + 0.1343 NO3- + 0.1343 H+ ↔ 0.0143 C5H7O2N + 0.06 N2 + 0.3505 H2O + 0.0952 CO2
