Imagine this: you are 13 years old‚ just about to finish middle school getting ready to start high school with all your friends‚ when one day you came home from school and the bombshell hits. Your mum sits you down and tells you the news that nobody wants to hear at that point in life‚ you find it hard to remember the whole talk. all you seem to remember are the words‚” WE ARE MOVING.” when you finally get to terms with it‚ you ask where to‚ with the hope it won’t be too far so it won’t be a complete

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

conducting surface with a thin layer (seldom more than 0.001 in [0.025 mm] thick) of metal by electrolytic deposition. In electroplating‚ the object to be plated is made the cathode in an electrolytic bath of salts of the metal to be plated. The anode may be an unaffected metal‚ or‚ more commonly‚ the metal to be plated. An electriccurrent is passed through the solution‚ which results in the deposition of a thin metal plating in the desired thickness on the cathode. Traces of organic materials are usually

attraction between two oppositely charged ions. Ionic bonds are formed between an metal and a non-metal. The metal loses an electron or electrons form its highest energy level becoming a positively charged Ion and the non-metal gains an electron or electrons in its highest energy level‚ becoming a negatively charged Ion. Covalent bonds are strong bonds between two non-metal atoms. A covalent bond forms when two non-metal atoms share a pair of electrons. The electrons involved are in the highest occupied

Lithium‚Sodium‚Potassium‚Rubidium‚Caesium and Francium are all part of group 1.They are metals that can be easily cut.After being cut‚it is shiny but it quickly tarnishes due to the fact that the metal reacts quickly with oxygen or water.The shiny surfaces of Sodium quickly tarnishes more quickly than Lithium and Potassium more tarnishes more quickly than Lithium.This shows that the reactivity increases as we move down the group.

experiment is to study a set of metals and their reactions reactions using different metals in an ordered activity series‚ the goal is to find the relative reactivity of them.Discovering why metals react with certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings‚ or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals‚ this is important. Manufacturing
