The recommended amount of calcium nitrate to add per gallon of water depends on the specific application and concentration needed. It is important to follow the instructions on the product label or consult with a professional for the correct dosage.
When ammonium nitrate and calcium hydroxide are added at the same time, they will react to form ammonium nitrate and calcium nitrate along with water. This reaction is an example of a double displacement reaction where the cations of the two compounds switch places.
When aqueous calcium nitrate is added to aqueous lithium sulfate, a double displacement reaction occurs. The calcium and lithium ions switch places to form calcium sulfate and lithium nitrate. This reaction results in the formation of two new compounds: CaSO4 and LiNO3.
Any reaction occur.
The recommended amount of calcium nitrate to add per liter of water depends on the specific application and concentration needed. It is important to follow the instructions on the product label or consult with a professional for the correct dosage.
When calcium chloride (CaCl2) is added to silver nitrate (AgNO3), a double displacement reaction occurs. The insoluble silver chloride (AgCl) precipitates out of solution while calcium nitrate (Ca(NO3)2) remains in solution. The balanced chemical equation for this reaction is: CaCl2 + 2AgNO3 → 2AgCl + Ca(NO3)2.
When nitric acid is added to eggshell, a chemical reaction occurs where the calcium carbonate in the eggshell is dissolved by the acid. This reaction produces carbon dioxide gas, water, and calcium nitrate. The eggshell will dissolve, leaving behind a liquid containing dissolved calcium nitrate.
Calcium nitrate and magnesium will not react since calcium is more reactive than magnesium and so, magnesium does not displace calcium (See Reactivity Series). However, if Calcium nitrate is in aqueous solution (dissolved in water), some bubbles may be seen when Magnesium is added to it, since the Magnesium would be reacting with the water and producing hydrogen bubbles.
silver chloride should precipitate out.
When nitric acid is added to egg shell, it releases nitrogen dioxide gas. This reaction is a result of the acid reacting with the calcium carbonate in the eggshell to produce calcium nitrate, water, and nitrogen dioxide gas.
The appearance of chromium will not change if added to the sodium nitrate since it cannot displace nitrate from the sodium.
Chromium will be reddish brown in appearance if added to sodium nitrate.
Call the unknown mass m. Then, from the problem statement, m/(400 + m) = 12.5 % = 0.125. Applying standard algebra techniques, multiply both sides of this equation by (400 + m) to result in m = 0.125(400 + m); m(1 - 0.125) = 400 X 0.125; 0.875m = 50; m = 57.1 grams, to the justified number of significant digits.
