Hydrogen Peroxide & Inorganic Peroxy Compounds Hydrogen Peroxide Hydrogen peroxide (H2O2) is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid‚ slightly more viscous than water. In dilute solution‚ it appears colorless. Reactions Decomposition Hydrogen peroxide decomposes exothermically into water and oxygen gas spontaneously: 2 H2O2 → 2 H2O + O2 This process is thermodynamically favorable. It has

IRON (METAL) Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole‚ forming much of Earth’s outer and inner core. It is the fourth most common element in the Earth’s crust. Iron’s very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars‚ Like other group 8 elements‚ iron

The Process of underwater welding was first used back in the 1930’s by the soviet engineer Konstantinovich Khrenov. It was a very vast process used by the Soviet Navy. Today underwater welding is far more advanced and safer. Now‚ don’t get me wrong this procedure is immensely dangerous far beyond belief. This topic I chose was something I was very intrigued by‚ I want to become an exceptional welder‚ and this would be something to master in the future. I have accumulated a lot of knowledge on the

Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

previous 50 years‚ welding has become more productive‚ automated‚ and safer. Generally‚ the welding norm was resistance based and performed with big machinery. The aerospace industry spurred the innovation of new ways to weld thin metal. At this point in history‚ all welding systems had good and bad aspects; the choice should be made with a balance between the different capabilities of the systems‚ including its power requirements and limitations. Manufacturers used this welding technology to hold

physically. Through the DMACC welding course‚ I would recieve my welding certificate to be able to weld commercially through DeeZee‚ Vermeer or another company of that prestige. Through the cost of the course itself and material needed‚ the cost of the entire class can spread through the thousands. Through the money granted‚ it will help me pay for the course then with that I can purchase the equipment needed outside of the course to then further my career and my path into welding.

Welding Engineering I have chosen welding as my future career job just because I have always had the urge for becoming that in life. Takes a lot of patience to accomplish welding and making it to becoming successful at it. My welding teacher in High School‚ Mr. Rambo taught me everything I know about this career. He has taught me how to mig‚ tig‚ and arc weld and a lot more amazing things. As a starting pay for a welding engineer you can make about 46‚000 to 106‚000 a year. The more knowledge
