Nitrate

After we gathered our materials we measured 23 g of sodium nitrate and 200 mL of water. After measuring the water we put the water in the small bag. Then we took the initial temperature of the water, which was 23 degree celsius. Then, we put the 23g of sodium nitrate into the big bag. After that we put the small bag(unsealed) into the big bag(sealed). Then, we mixed the two substances together. Once we did that…

called Nitrobacter converts nitrate to nitrate. Nitrate Assimilation The nitrate present in the soil is absorbed by plants through the root system in the form of NO3 - ions. But it cannot be used by plants directly. So it is first reduced to nitrite by the enzyme nitrate reductase. Nitrite is then converted to Ammonia by the enzyme nitrite reductase series of steps requiring a total of eight electrons provided by reduced NAD and Ferredoxin (Fd). This reduction of Nitrate to Ammonia and its…

“Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total…

Reaction # Observations Equation 1 We mixed Aluminum Sulfate with Barium Nitrate in two test tubes. The Barium Nitrate is a clear liquid that had no smell. The Aluminum Sulfate also was a clear liquid with no scent. When mixed, the center of the liquid turned into a milky white precipitate. After 2 minutes the white substance sank to the bottom while the clear liquid sat on top. Al2(SO4)3(aq)+3Ba(NO3)2(aq)--> 2Al(NO3)3(aq)+3BaSO4 (s) 2 First we felt the material of a piece of Magnesium.…

domestic terrorist attack place against the Oklahoma federal building. Ammonia was a key component used to create the high explosive, used y terrorist that day. The terrorist used 50-pounds bags of ammonium nitrate. They built a bomb that contained more than 5,000 pounds of ammonium nitrate fertilizer, mixed with 1,200 pounds of liquid niromethane and about 350 pounds of…

prints visible on porous surfaces, forensic scientists use one of three methods; Silver Nitrate, Ninhydrin and Iodine fuming. These three methods are known to be the most effective ways for developing prints. Silver Nitrate is best known for developing prints on porous surfaces. Specimen on these surfaces can either be sprayed by or immersed in a diluted form of Silver Nitrate. Three variants of silver nitrate solution are used, a 1% w/v aqueous solution, a 3% w/v aqueous solution, and a 3%…

How does table sugar react with potassium nitrate? Will the ratio between table sugar and potassium nitrate affect the product produced? According to “Smoke Bomb” (2017), smoke bomb is a firework designed to produce smoke when ignited. Smoke bombs are used in various ways such as signalling aircrafts, paintball guns, airsoft guns, military units, self-defence, entertainment and pranks. Smoke bombs was first invented by a British inventor, Robert Yale in 1848. He started by developing…

properties are defined as a substance changing without changing the chemical properties. The physical properties of gunpowder include the boiling point of potassium nitrate which is found in 673⁰ K and the melting point is 607⁰ K. Following ingredients inside of gunpowder (also known as black powder) are Sulfur (S), Charcoal, and Potassium nitrate…

This report will compare the water quality of Freshwater Creek over the last three years using chemistry to show how the three chosen parameters are all linked and affect the overall quality of the water. Water is combination of two atoms, oxygen and hydrogen. When two hydrogen’s bond with one oxygen it makes a covalent bond. A covalent bond relates to the outer shell of electrons (valence shell) being shared with the neighbouring molecule for them to bond. A covalent bond only occurs between…

then took a blue test strip of silver nitrate and placed it into a zip lock bag for our control. We would also take to additional blue strips and place one into a zip lock bag and begin respiration process of exhaling into the bag to test for the excretion of water. For part B we tested for the excretion of salt by rubbing a small piece of cotton in a clean palm, non-cleaned palm, and urine and then placing the cotton into a test tube. 5-6 drops of silver nitrate…
