Sodium in Water Chemistry Demonstration - ThoughtCo
2019/10/28· The sodium in water chemistry demonstration is a spectacular demonstration that illustrates the reactivity of an alkali metal with water. What to Expect A small piece of sodium metal will be placed in a bowl of water. If a phenolphthalein indior has been added to the water, the sodium will leave a pink trail behind it as the metal sputters and reacts.
What Happens When Dilute Hydrochloric Acid Is Added …
Answer (1 of 2): Hydrogen gas and iron chloride are produced Fe + 2HCl -----> FeCl2 + H2 this means iron displaces hydrogen from HCl bcoz it lies above hydrogen in the reactivity series, and FeCl2 is formed with the evolution of Hydrogen gas

Hard water - Wikipedia
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.
What happens when acid reacts with limestone? | …
Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don''t dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions

Heart Scan for Calcium Scoring to Lower Your Risk of a …
What happens during a CT heart scan? The procedure is performed by a CT technologist with the assistance of a radiologist. Once you arrive, you may have to change into a gown if there is any metal on your clothing. The technologist will explain the procedure
What solution when added sulfuric acid and silver nitrate …
2013/7/13· A better choice than calcium chloride would be barium chloride, BaCl2. Reacting with H2SO4, barium ions produce BaSO4 which is much more insoluble than calcium sulfate. Depending on the concentrations, you might not see a CaSO4 precipitate. The chloride
Mineral Deficiency | Definition and Patient Eduion

Experiment III - University of Michigan
Will a metal ion with a low electronegativity (such as Cs+) be a better or worse oxidizing agent than a metal ion with a high electronegativity (such as Ga3+)? Try some questions below to see if you can figure out whether the following pairs are oxidizing agents or reducing agents, and predict which one is the stronger based on their position in the periodic table.
Oxide | chemical compound | Britannica
Oxide, any of a large and important class of chemical compounds in which oxygen is coined with another element. With the exception of the lighter inert gases (helium [He], neon [Ne], argon [Ar], and krypton [Kr]), oxygen (O) forms at least one binary oxide with
