Lab design –Voltaic Cells Aim Of Experiment In this experiment‚ we are going to make a battery by making an electron current between the metals Zinc and Copper. We aim two study the voltaic cells and the transfer of electrons from the metal to the ion. The tendency for the electrons to flow from one chemical to another‚ such as from the zinc metal to the copper ion as shown here‚ is something that can be channeled and controlled. Channeling the flow of electrons is what we will take up in this

3. RESULTS AND DISCUSSION 3.1. Powder X-Ray diffraction analysis The grown Cd doped LSMH crystal were subjected to powder X-ray diffraction studies using a Rich Seifert X-ray diffractometer employing CuKα (1.54058 Å) radiation‚ scanning angle ranging from 10° to 70° at a scan rate 1°/min to confirm the crystalline phase of the grown crystal. Fig 2 shows the X-ray powder diffraction patterns of pure as well as Cd doped LSMH single crystals. The obtained (h k l) values are indexed using the JCPDS

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

Before the 1900s‚ tin was commonly used to package household foods. Since it protected the foods inside‚ and it could be bent with ease‚ it was regarded as an inexpensive‚ easy and health conscious way to keep foods fresh. Some of its disadvantages‚ which lead to its defeat to aluminum‚ included the fact that it could only be rolled thicker than aluminum; it became brittle when warm‚ reducing its malleability greatly‚ and the tin foil created a strange aftertaste‚ which was undesirable to many.

Honors 1-18-12 Relative Solubility of Transition Elements Introduction: In this lab we evaluate the solubility of compounds of iron‚ copper‚ zinc‚ and mercury in both water and acid. Coming into the lab we know that iron‚ copper‚ and zinc are all found in the the same row of the periodic table‚ while zinc and mercury are found in the same column. The transition metals are found in groups 3 to 12 and periods 4 to 6. Rows are known as periods and columns are known as groups. They share characteristics

Chromium‚ Chromiuim‚ Chromium‚ Oh my oh my‚ sweet Chromium What did Nicolas Louis Vauquelin say when he first discovered you? Did he know that you were going to have 24 protons and exactly 24 electrons? Or even 28 neutrons… No? So how did the world figure you all out? Was it because you were such a beautiful silvery transition metal? Or maybe it was your mesmerizing amount of atomic mass… Ya’ know‚ it being 51.996. Are other elements attracted to you because you are simply‚ Odorless
