corrosion but the term is restricted to iron or products made from it. Iron is easily prone to rusting making its surface rough. Chemically‚ rust is a hydrated ferric oxide. Rusting‚ an electrochemical mechanism: Rusting may be explained by an electrochemical mechanism. In the presence of moist air containing dissolved oxygen or carbon dioxide‚ the commercial iron behaves as if composed of small electrical cells. At anode of cell‚ iron passes into solution as

Problem: What methods could be used to extract materials from the given mixture that contains iron filings‚sand‚salt and small stones? Background There are things that must be understood before doing this lab. The first thing that must be understood is a mixture. A mixture has two or more pure substances‚ and the substances keep their chemical compositions (study.com).The next thing to apprehend is filteration.

When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

experiment‚ we were trying to see whether copper‚ after a chain of chemical reactions‚ will revert back to its elemental form. Procedure: First‚ I added nitric acid with copper in a beaker‚ which turned into a copper nitrate‚ a blue-green solution. Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. Once the solid appeared‚ I poured
