Over the past 100 years‚ science has been captured an important position in our daily life. To us‚ science isn’t only taking an important role on medical‚ technology and investigating‚ but also to protect us in wartime by inventing new ordnance. Scientists are usually recognized by inventing different new methods or inventions to assist for their own countries‚ and that’s the way they used to fight for the countries and defeat the enemies. Many scientists have been working on science project which

nitrateAmmonium Nitrate How they are manufactured? Ammonium nitrate is made commercially by passing ammonia gas (NH3) and a water solution of nitric acid (HNO3) through a pipe. The ammonia combines with the nitric acid to form ammonium nitrate. The formula for this reaction can be written as NH3 + HNO3 → NH4NO3. Large amounts of heat are released during the reaction‚ so the pipe and supporting equipment must be very strong. The solution of ammonium nitrate in water is allowed to evaporate‚ leaving

Limestone is a sedimentary rock composed of calcium carbonate (CaCO3). There are various types of limestone‚ as well as different methods for formation. When limestone is formed through precipitation of water‚ it is called chemical limestone. When limestone is formed from the shells or skeletons of dead marine organisms‚ it is called organic limestone. Limestone is soluble‚ so it is very common in Karst landscapes. Limestone has many uses‚ but it’s most common use is as a building material for architectural

Nitrate is an element that can not be observed by any of the senses other than sight and touch because it is known to be odorless and tasteless. Nitrate starts within the earths soil but filters into water and plants when it is mixed with rain water that is either cycled back into larger bodies of water or into the plants that take the water from the soil
