2-Chlorobutane reacts slower than 2-Bromobutane because the chlorine atom is smaller than the bromine atom, meaning the electrons are held closer to its nucleus. there is better orbital overlap between carbon and chlorine making the C-Cl bond stronger. The Br is large and has poor orbital overlap in the C-Br bond, making it weaker. Weak bonds are easier to break, therefore the C-Br bond will break more readily than the C-Cl bond.
A common nitrate test is known as the brown ring test or iron ring test.It can be performed by adding FeSO4 to the solution, then slowly adding concentrated sulfuric acid and watching for a brown ring on the test tube, which will indicate the presence of the nitrate ion.[Fe(H2O)5NO]SO4 forms a brown ring in the middle of the solution produced by the reaction;the 'NO' part of this complex comes from the auto-redox of nitrate NO3- to NO (and O2) by sulfuric acid.Note that the presence of nitrite ions will interfere with this test, reacting directly as 'NO'.Do NOT use nitric acid, since it gives nitrate ion which gives a positive result anyway).
Silver does not combust as it is not a very reactive metal. It corrodes slowly by reacting with oxygen in the atmosphere.
To properly dispose of Silver Oxide :• Add 100 volumes of distilled water to 1 volume Silver Oxide powder. (glass container only)• Add common household Hydrogen Peroxide, very slowly, with lots of stirring. (glass or plastic stirrer only)• Add Hydrogen Peroxide, stirring, until all of the Black Powder has turned gray. (lots of bubbles - Oxygen)• You now have reduced Silver Oxide into harmless Silver Powder. (You may want to keep it)• NOTE : Silver Powder also breaks down the Hydrogen Peroxide, forming Oxygen bubbles.
Gold does not react with air or water, so it does not tarnish or corrode easily. Copper reacts slowly with air and water to form a patina. Silver reacts with sulfur compounds in the air to form tarnish. Iron reacts quickly with oxygen to form iron oxide (rust).
ammonium nitride is a water soluble solid. it is formed (or so Ive read) by the double displacement reaction between lithium nitride and ammonium nitrate, leaving lithium nitrate and ammonium nitride. it is highly unstable and will explode violently if heated vigorously but can be made to decompose slowly if gently heated to around 100 degrees, for that reason i am guessing it would be safer to boil a dilute solution of the compound, but this may still be dangerous.
copper is placed above the silver in the ractivity series which indicates that copper is more reactive than silver . when a copper coin is kept immersed in a solution of siler nitrate ,silver from its solution will deposit on copper coin . copper slowly displaces silver from the silver nitrate solution and the colour of solution changes from colourless to blue due to the formation of copper nitrate . the copper coin will disappear and silver will percipate out .
Dissolve each of the silver nitrate and potassium iodide separately in water, then mix the two solutions slowly with stirring. Silver iodide will precipitate and can be separated by filtering it from the liquid.
Evaporating slowly thee water ammonium nitrate is obtained.
A Nitrate.
It's a precipitation reaction. A yellow precipitate will form, kind of like a bunch of little tiny yellow particles. At first, it will look a little like paint, but if you let it sit, the yellow particles will slowly drift to the bottom.
Usually a slow-burning material like cotton or hemp soaked in a solution of saltpeter or potassium nitrate is placed on a linstock to make it burn slowly. This helps control the ignition of the gunpowder in a firearm.
By the process of titration. Basically, you pour about of 100ml of distilled water to a beaker through your desired quantity of food. For example, you put some chips on top of the beaker so they wouldn't leak in there, and just pour water through it so the salt, which is water soluble, gets drained to a beaker with out the chips but with the water. Then...1. Prepare 100ml of solution with salt in it (previously described as extracting salts from foods into distilled water.)2. Prepare solution of silver nitrate of concentration 0.2mol and add it into a burette.3. Pour 10ml of salty solution into a beaker and add 10 drops of potassium chromate.4. Slowly add silver nitrate onto the salty solution from the burette and measure how much silver nitrate is required to make the solution reddish.
To prepare a solution with bismuth nitrate pentahydrate and NaOH, first dissolve a known amount of bismuth nitrate pentahydrate in a solvent (such as water) to make the initial solution. Then, slowly add NaOH solution to the bismuth nitrate solution while stirring until the desired pH or reaction completion is reached. Be cautious as the reaction may release heat.
now the silver is closing very slowly
To crystallize potassium nitrate from its aqueous solution, you can gradually heat the solution to evaporate the water until crystals start to form. Then, allow the solution to cool slowly to encourage crystal growth. Finally, filter the solution to separate the crystals from the remaining liquid.
To prepare a supersaturated solution of potassium nitrate in water, you would first dissolve an excess amount of potassium nitrate in hot water, stirring continuously until no more of the salt can dissolve. Then, let the solution cool slowly without disturbing it, which will allow the excess salt to form crystals at the bottom, creating a supersaturated solution above it.
The 1884-o silver dollar is worth $20 to $35 circulated and up to $200 uncirculated. The prices are slowly going up every year.
