Iron‚ which has the chemical symbol Fe‚ is an extremely useful metal and the most common element 0n the planet Earth. Here are some of the more common uses of iron in the world today. Uses of Iron * Iron catalysts are used in the Haber-Bosch Process to produce ammonia and the Fischer-Tropsch Process to convert carbon monoxide to hydrocarbons used for fuels and lubricants. * Iron metal is strong but is also quite cheap. Therefore‚ it is the most common metal in use today. Most automobiles

Corrosion of Character Flexibility Flexibility in the economy can be defined in numerous ways. According to Sennett to be flexible is to be able to adapt to changing circumstances and not to be broken by them. This idea of being able to adapt to changing circumstances can be applied quite easily to the economy and how we as a society or individual have to be accommodating and willing to change and roll with the punches. A few elements pertaining to flexibility are drifting‚ taking risks and

| 2012 | | Toby Rheinberger Lab Partner: Jeremy Saba | [The Effect of surface area to volume ratio and solute concentration on osmosis.] | The aim of this experiment was to test the effect of surface area on osmosis and the effect of solute concentration on osmosis. To test this aim to hypotheses were devised. 1) If potato pieces are immersed in various salt solutions‚ then the pieces with the greatest surface area to volume ratio will experience the greatest weight change‚ because more

Introduction- This experiment was conducted in order to use a parachute to reduce the collision force by decreasing the acceleration of which the water balloon is traveling causing it not to burst. When the balloon was dropped without a parachute the force of gravity was pulling it towards the ground therefore causing it to accelerating at such a fast rate that when it hit the ground the amount of force it hit the ground with was so great that the balloon popped. However when the balloon was dropped

in rust and corrosion when dipped in different solutions. Corrosion is the reaction between a metal and it’s surrounding environments. Corrosion occurs when a metal (for example Copper) and different environments (such as water‚ air‚ acids‚ bases‚ etc.) come into contact. Corrosion is the act of deterioration in metals.[1] A chemical reaction occurs between the metal and it’s environments Eg. Copper + Oxygen ( Copper Oxide Cu (I) + O ( CuO Rust is very similar to corrosion but only occurs

Affecting the Rate of a Chemical Reaction Title of your investigation An investigation into the factors affecting the rate of a chemical reaction 1. Aim of investigation To investigate the major factors that affect the rate of corrosion. 2. Motivation (explain why you have chosen to investigate this particular topic) I have chosen to examine this experiment as it applies to our daily lives. Rusting of metal occurs every day whether it’s the nails on our deck or that rusting bicycle

CORROSION AND ITS CONTROL CORROSION * corrosion can be defined as the degradation of a material due to a reaction with its environment. * Degradation implies deterioration of physical properties of the material. This can be a weakening of the material due to a loss of cross-sectional area‚ it can be the shattering of a metal due to hydrogen embrittlement‚ or it can be the cracking of a polymer due to sunlight exposure. * Materials can be metals‚ polymers (plastics‚ rubbers‚ etc.)‚

The process by which some metals when exposed to atmospheric condition i.e.‚ moist air‚ carbon dioxide form undesirable compounds on the surface is known as corrosion‚ The compounds formed are usually oxides . Rusting is also a type of corrosion but the term is restricted to iron or products
