Copper(II) sulfate

This is a test to see if SO4 is present in the solution. If the mixture has a white precipitate of Barium Sulfate, then the solution has a sulphate ion present (4). Taking one of the remaining test tubes, add 0.1 mL of BaCl2 into the solution and mix well. HCl Test Fig 5. If HCl is present in the solution, bubbling and a strong smell of ammonium should be…

Avogadro’s number. Avogadro’s number will be determined by setting up an electrochemical cell to oxidize a copper electrode. The results of the amount of copper deposited and the average current used will be used to calculate a value for Avogadro’s number. Techniques used: In this experiment, different techniques will be used to collect the required data, such as taking the mass of the copper electrode on an analytical balance, preparing the electrodes, using LabQuest, and assembling an…

Based on Otzi’s belongings I think he was a hunter. IF he was a farmer I believe he would have brought some of his own food with him. Even though he had arthritis he seems to be too skilled with a bow and arrow to just be a farmer since 1 arrow had 2 different people’s blood on it. I also think he lives with a group of people since he was whipworm. Whipworm is spread by human poop which makes me think he can’t get sick of his own poop. I don’t believe he died from this illness since he does not…

Bending pipes using a pipe bender is not an easy or simple job to learn how to do. If you are just learning how to bend pipes using a pipe bender, use these three tips to help you become more effective and precise at this new skill. #1 Measure From The Center When working with pipes, you always need to verify that you are working with the correct size of pipe. The best way to measure a pipe is to place it in the pipe bender so that it is secure, and then measure the length of the pipe,…

inches apart. Cut out a piece of wire mesh to fit the circumference of the tin tuna can, and mold the wire to the side of the can, creating a grill for the Cheetos to burn. Wrap the sides of the can with foil tape, without blocking the holes. Obtain a copper pipe, 11 5/8th inches in height, and 5/8th inch diameter, and tape the the pipe to the inside of the can with 5 1/2 inches sticking out the…

deep blue pigment which was originally made by grinding lapis lazuli(deep blue stone) into a powder. Lead-tin-yellow is a yellow pigment also known as "Yellow of Old Masters". Malachite is a copper carbonate hydroxide mineral. Verdigris is a green pigment made through a process which that occurs when copper, brass, or bronze, is exposed to air over a period of time.Vermilion is a red pigment made from a powdered mineral called cinnabar. A couple examples of these materials used in the painting…

Otzi the Iceman PBS NOVA Iceman Murder Mystery 2011. YouTube, 16 Feb. 2013. Web. 23 Oct. 2016. Jessica Alcala Professor Patrick O’ Neil Anthropology Introduction: In September 1991, a pair of hikers wandered off the trail in the Italian Alps discovered a frozen body laying on a rock. The body was later confirmed by experts to be the preserved body of a man who was about five thousand years old during the the time of the Neolithic era. The man was named “Otzi” after the…

experiment was to calculate the percent yield of copper after conducting series of chemical reactions. To study the % yield of copper in the copper cycle, the initial mass and final mass of copper was measured. The chemical reactions involved in the copper cycle are dissolution, precipitation, dehydration, and oxidation/reduction. First, copper was reacted with in a beaker to form (aq) and . The purpose of the dissolution reaction is to convert the copper into solutes in the forms of…

Copper is one of the oldest metals known to man. Copper dating back to ancient time was discovered in Iraq. According to webelements.com, origin of name is from the Latin word "Cuprum" meaning the island of "Cyprus". Copper symbol is Cu. Copper atomic number is 29 and atomic mass of 63.546 amu. Copper is located in the 11th group on the periodic table. Copper is a transition metal, meaning metals that can be stretched into thin forms, such as wire (this characteristic is called "ductility"), and…
