They do not have the love feeling to the nature and throw garbage or any chemical substances anywhere including the river‚ the sea and any water sources. So this chemical substance will harm the water and we as the user will use the water without notice that we use the contaminated water. Slowly or in the long term our body will be affected.

1.0 INTRODUCTION Bomb disposal is the process by which hazardous explosive devices are rendered safe. Bomb disposal is an all encompassing term to describe the separate‚ but interrelated functions in the military fields of Explosive Ordnance Disposal (EOD) and Improvised Explosive Device Disposal (IEDD)‚ and the public safety roles of Public Safety Bomb Disposal (PSBD) and the Bomb Squad. Many shells‚ bombs and munitions fail to explode‚ leaving them around the battlefield after the fighting is

A Critical Analysis of the Effects of Chemical Castration and Physical Castration on the Recidivism Rates of Sex Offenders Introduction This paper examines the effects of chemical castration and physical castration on the recidivism rates of sex offenders. Using theory integration or the multifactor approach‚ the findings reveal there are several factors influencing sex offender recidivism. Both chemical castration and physical castration have the potential to reduce the recidivism

Assignment 5 Sheet Harbour Chemicals Sheet Harbour Chemicals (SHC) manufactures chemicals used in the paint industry. The process involves three departments. Chemical A‚ which is purchased for $3 per liter‚ is processed through Department 1 in batches of 100 liters. Each batch of chemicals processed through Department A produces 70 liters of chemical B and 30 liters of chemical C. Chemical B is sold for $10 per liter. Chemical C is used in Department 2 to produce chemicals D‚ E‚ and F. Department 2

Chemical Engineering In the future I would like to become a chemical engineer. I really enjoy chemistry and hands on work “Chemical engineering is the application of chemistry to large scale industrial systems.” (Chemical engineering). I enjoy helping build different things like skateboards‚ ramps and‚ fixing parts on different things. When I took the sixteen personality quiz it said I was a virtuoso. The virtuoso likes hands on work and exploring ideas which I think fits my personality perfectly

Another fact about hydrogen is that our sun converts 600‚000‚000 tons of hydrogen into 596‚000‚000 million tons of helium. The rest of it is converted into energy (according to Einstein’s law: E= mc2) and is sent to earth. That makes the light of dawn‚ the heat of summer‚ and the fading glow at dusk. The next element I will discuss is cerium. (The only reason I am doing this one is because it is use in flint
