Although water-soluble, ammonium attaches readily to clay and organic matter particles (in much the same way iron is attracted to and held on a magnet), thus preventing it from leaching away. Then ...

Where can you get your hands on these materials? Instant cold packs use ammonium nitrate and water to start an endothermic reaction. The potassium chloride can be found in the grocery store as a ...

Endothermic reactions include solid citric acid and sodium hydrogencarbonate, and dissolving ammonium nitrate in water. Demonstrate a spectacular reaction such as the thermite reaction or the ...

Two dry solids --- barium hydroxide and ammonium nitrate --- are mixed to produce an endothermic reaction. The temperature of the mixture drops approximately 45oC and is cold enough to freeze the ...

Ammonium nitrate (NH 4 NO 3) is commonly used as a fertiliser. Given the relative atomic mass of hydrogen is 1, nitrogen is 14 and oxygen is 16, calculate the percentage of ammonium nitrate that ...
