I would be most appreciative if you could give me advice on how to solve this problem. I''ve exhausted myself trying to solve
Sodium bicarbonate - Wikipedia
Sodium bicarbonate mixed with water can be used as an antacid to treat acid indigestion and heartburn. Its reaction with stomach acid produces salt, water, and carbon dioxide: NaHCO 3 + HCl → NaCl + H 2 O + CO 2 (g) A mixture of sodium bicarbonate and polyethylene glycol such as PegLyte, dissolved in water and taken orally, is an effective gastrointestinal lavage preparation and laxative

A 0.0677g sample of magnesium metal reacted with …
A 0.0677g sample of magnesium metal reacted with excess hydrochloric acid to produce 69.9 ml of hydrogen gas. The gas was collected over water at 21.0 degrees Celsius. The levels of water inside and outside the gas collecting tube is identical. The water vapor pressure at 21.0 degree Celsius is 18.6 mmHg and the atmospheric pressure is 755 mmHg. Calculate the experimenal molar volume of
Reaction between Aluminum and my Chlorinated pool …
2013/9/23· HCl gas is not being produced. The HCl resulting from chlorine oxidation of aluminum dissolves readily in water to lower pH and to form chloride salt. Aluminum already reacts with oxygen in air to form a passivity layer of aluminum oxide.

Calcium Salt - an overview | ScienceDirect Topics
It is soluble in water up to a concentration of about 1 g in 7.5 ml, whereas the calcium and sodium salts are slightly more soluble, to the extent of about 1 g in 4 ml of water. Cyclamate is rather acidic (the pH of a 10% aqueous solution being 0.8–1.6), whereas similar solutions of the calcium and sodium salts are neutral (pH 5.5–7.5).
