A possible extension is to hold a cold piece of metal or glass above the place where you burst the bubbles so that the water vapour that forms during the reaction condenses on the metal or glass. Place approximately 1 g of the magnesium pieces in the test tube, but do not add the hydrochloric acid until everything else is ready to be asseled.

CBSE Class 10 Science Lab Manual - Properties of Acids …
On reacting with zinc metal, HCl forms a salt, zinc chloride (ZnCl 2) and hydrogen gas (H 2) is liberated. Hydrogen gas burns in air with a blue flame and produces a pop sound. HCl reacts with sodium carbonate (aqueous/solid) to liberate carbon dioxide (CO 2 ) which turns lime water milky due to the formation of calcium carbonate.

Dissolving calcium hydroxide (∆Hsoln = -16.2 KJ/mol) in …
Dissolving calcium hydroxide (∆Hsoln = -16.2 KJ/mol) in water is an exothermic process. How much lithium hydroxide (∆Hsoln = -23.6 KJ/mol) is needed to deliver the same amount of heat as 15.00 g of Ca(OH)2? Hello everyone, thank you for taking a look at my question. 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 silie - Wikipedia
Properties Sodium silies are colorless glassy or crystalline solids, or white powders. Except for the most silicon-rich ones, they are readily soluble in water, producing alkaline solutions.Sodium silies are stable in neutral and alkaline solutions.In acidic solutions, the silie ions react with hydrogen ions to form silicic acids, which tend to decompose into hydrated silicon dioxide gel.
