Silver is an element that is found on the Periodic Table. The element silver is symbolized on the periodic table with the letters Ag. The symbol Ag of silver comes from a latin word for silver which is argentum. Silver on the Periodic Table is found in group 11. Silver has an atomic number of 47. The atomic number determines the chemical properties of an element and is placed on the top of the symbol on the periodic table. The mass number of the element silver is 107. To determine the atomic number you use the number of protons and neutrons in the element. Silver has 60 neutrons which is a subatomic particle found in the nucleus of every

Procedure- The procedure for this lab includes many simple steps and a few different things we are testing. Our first Procedure was to combine water and salt to see what kind of reaction it would make. First we fill the graduated cylinder with 100 ml of water. We then measured 1.0 grams of table salt on a balance to get an accurate amount. After, we took the measured amount of salt and poured it into the water filled beaker. Lastly, we watched and recorded the reaction.

The purpose of the lab copper- silver nitrate reaction is to find the mole relationships between reactants and products. My hypothesis was that the mole relationship between silver and copper will be 2 mol Cu: 1 mol Ag ratio. My hypothesis is supported by the data I found during the lab. First evidence, in the beginning of my calculation I have to determine the mass of copper that reacted during the experiment and converted to moles of copper and got .0033 moles of Cu. Next, I determined the mass of silver produced during the experiment and converted into moles of silver and got .0063 moles of Ag. After I found the moles of copper and silver, I determined the value of the ratio of .0063 moles Ag /.0033 moles Cu and got 1.90 moles. 1.90 mol

Silvershell Beach is the home to many different aquatic species and other forms of wildlife. Last lab block the class and I went into the ocean at Silvershell beach and took seven different seine net samples. With each sample we took, we noticed a variety of different organisms. As we moved around different areas of the ocean, we would come out with changing species and number of species that we did not find in other areas of the water. Species we found included sea robin, hermit crabs, moon jellies, minnows, shrimp, eels, and more. Sample one and two were taken from around the same area in the water and there was a reappearance of three of the species. In sample one we found hermit crabs, minnows, moon jellies, and a sea robin. In sample two

Strontium nitrate, the limiting reagent, was poured into the copper(II) sulphate solution, the excess reagent, rather than the other way around. This is a minor systemic error, because even if some of the strontium nitrate remained in its initial beaker, the beaker was thoroughly rinsed out multiple times. The error causes the final mass of the filter paper and precipitate to be slightly decreased, as not all of strontium nitrate reacts with the copper(II) sulfate. This can explain why the percent yield in 92.2%.

to compare the results, and neither solution was expected to produce an observable chemical reaction. The procedure was the same as used for the test with 6M HNO3 and 0.1M AgNO3 solution and the test with 6M HCl and 0.1M BaCl2 solution. A third experiment used was the flame test. First, a scoopula was used to place 0.1 grams of the unknown compound in a test tube, and a wash bottle was used to add approximately 2 mL of deionized water to create a solution.

In a test tube, 0.5mL of the sample will be added with 0.5 mL of water and shaken vigorously. Take note for its solubility by parts (0.5mL is one part). Keep adding parts of the solvent until the sample is soluble. If not, add until ten parts of the solvent and determine its solubility. To separate test tubes, water will be replaced with ethanol, chloroform, ether, and acetone as solvents. Same procedures were

This experiment was performed to observe the formation of silver chromate from a reaction between silver nitrate and potassium chromate. In this double displacement reaction, the cations and anions of the two reactants swapped and produced silver chromate and potassium chromate. An indication of a reaction occurring between the silver nitrate and potassium chromate was the production of a red solid from the yellow potassium chromate and the clear silver nitrate. Potassium nitrate has its uses in applications such as fertilizers and food preservation while the other product of this reaction, silver chromate, has little application in the real world.

When solid mercury (II) nitrate is heated, it decomposes to form solid mercury (II) oxide, gaseous nitrogen dioxide, and oxygen.

Our theoretical yield of Silver is 0.370 g, and our actual yield is 0.351 g. To begin with, I was amazed of the process of making silver from a little piece of metal and silver nitrate solution even though it took 3 days to complete this lab. On the first day, Michael mostly did all the measurements and testing, while Mai and I was responsible for the calculations, including taking pictures and recording down the data. Firstly, our group balanced out the chemical equation, which is very important for the later steps of our procedure. The equation is 1Cu+2AgNO3Cu(NO3)2 +2Ag ( you can see how to balance it out in the procedure and we are using Copper II for this lab).
