SCIENCE REPORT AMMONIUM NITRATE NH4NO3 Problem Our task was to investigate what the optimum ratio of solute to solvent that will produce the maximum cooling/heating effect? Hypothesis With a smaller quantity of water (50mls) and the same amount of Ammonium Nitrate added. After any period of time the mixture will be a cooler temperature than that of a mixture with a larger quantity of water.

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

Nitrate Paper For Mrs. Williams 4th Period NO3- or otherwise known as Nitrate‚ not to be confused with Nitrite‚ is located in period 2 group 15. 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

Nitrate concentration comparison in the Suwannee River Basin Sara Santarelli Project summary Goals: Project Description A. Since 1971 nitrate concentrations in the Suwannee River have been increasing at a rate of 0.02 mg/L per year. The rise of nitrate concentrations found in the Suwannee River basin must be addressed. This problem is of extreme significance not only to hydrogeologists‚ but also anyone who cares about preserving natural Florida. Attempts to remove nitrate concentrations

The poem Fern Hill‚ by Dylan Thomas‚ is about person’s life from childhood to his eventual death. My reaction to the poem at first was confusion. But with repeated reading‚ more clarity was reached. In the work of a critic‚ named Thomas Steele‚ the interpretation derived from the poem resembled mine in most of the points. The two major points of Fern Hill that we both agreed upon is what the poem is actually about‚ and the passage of time. These two subjects are major themes in Fern Hill. The
