Ammonium chloride caused the water to cool. This means that the Ammonium chloride drew energy from the water to help it dissolve. As a result of losing its energy, the water cooled down. Calcium chloride caused the water to warm up. This means that energy from the calcium chloride was released and the water absorbed this heat. As a result, the temperature of the water increased. 3. Since you are measuring the temperature of the water, let’s call that the system. Relative to the water, was this

The most common form of a primary cell is the Leclanche cell, invented by a French chemist Georges Leclanche in the 1860s. The electrolyte for this battery consisted of a mixture of ammonium chloride and zinc chloride made into a paste. The negative electrode is zinc, and is the outside shell of the cell, and the positive electrode is a carbon rod that runs through the center of the cell. This rod is surrounded by a mixture of carbon and manganese
very similar to the dry cell we use today. The positive pole is a rode of carbon embedded in a black manganese dioxide (MnO2) and Carbon particles and the negative electrode is made of zinc. The electrolyte consists of a mixture of ammonium chloride and zinc chloride made into a paste. This sits in between the negative and positive electrodes, which acts as an ionic conductor. When the cell is in use, atoms of the Zinc in the outer case are oxidized, giving up electrons and forming zinc ions.

and farm machinery. Over the next few days, bags of ammonium nitrate fertilizer, shipped from Nebraska via rail by TCT (Texas City Terminal Railway company) were being loaded onto the ship. By the morning of April 16, 1947, No. 2 hold had 1420 tons of ammonium nitrate while No. 4 had 880 tons. At 8 am that morning, a longshoreman smelled smoke coming out of hold No. 4. He alertly notified his co-workers and they moved several bags of ammonium nitrate fertilizer and found flames between the cargo
Parker Bell Mrs. West Chemistry, P.2 23 February 2014 The Haber Process The Haber process, otherwise known as the Haber-Bosch process is the reaction of Nitrogen (g) and Hydrogen (g), to produce ammonia; a huge part in the making of plant fertilizers. Ammonia is extremely difficult to produce on a large industrial scale, but the fertilizer made from it is responsible for sustaining one-third of Earth’s population. It was created by a chemist by the name of Fritz Haber, and it was then asked for another
strongly affects the rate as you will see in the results, so we have to try and keep it the same throughout the experiment. The reaction we are studying is very easy to monitor and time. All of the products in the solution dissolve into it (sodium chloride, sulphur dioxide and water), apart from sulphur, which makes the solution go cloudy, and forms a precipitate. This can be written down as s-1for example 15.7 s-1means 15.7 per second is the rate of the reaction. The rate is generally measured
were unable to retreat to a safe distance before the explosion. Nearly 200 injuries were also reported to have been treated at local hospitals (Wood, 2013). The explosion was said to be caused by the combination of the fire and large stores of ammonium nitrate fertilizer at the plant. This catastrophic event received immediate coverage from news agencies and journalists across the country. Multiple local, state, and federal Agencies responded to the scene as first responders and post event investigators
Reactions Between HCL and Marble Chips Planning I have decided to investigate the effect of different concentrations of hydrochloric acid on marble chips. I want to see how long it takes for 30cm of carbon dioxide to be given off once the acid and marble chips start reacting. I carried out a preliminary experiment to see what sort of time ranges I was going to expect because I wanted to get the concentration levels right otherwise I could have been waiting for a long time. I didn't have
very packs they are using. The chemicals inside each respective pack have various properties and applications that make them useful in their thermochemistry reactions. The compounds used are salts including sodium acetate and calcium chloride for hot packs and ammonium nitrate for cold packs. The compounds used for hot and cold packs

population of around 2,800 people. During the evening of Wednesday the 17th April of 2013 a massive explosion occurred in the small town. The West Fertilizer Company; which is owned by Adair Grain Inc. which had stockpiles of anhydrous ammonia and ammonium nitrate amongst other agricultural items; was the center and cause of the blast. It is not the first time that an explosion such as this has happened in the state of Texas; in 1947 in Texas city, Texas an explosion that caused nearly 600 deaths
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.

Masses will travel from all around the world, locally, and throughout the country all to participate in a once a year event. All of the participants take part in a temporary city that is Burning Man, and will light a giant wooden man, burning it to nothing but ashes here in Nevada’s Black Rock desert. This event is described as an experiment of itself and art that followers ten main principles, “radical” inclusion, self-reliance, and self-expression with the purpose of community cooperation, civic
substance would be considered conductive. Conductivity tells how well water can pass an electrical current. When inorganic substances are dissolved in the water it will greatly change the conductivity of water. Inorganic substances like sulfate, chloride, and nitrate will affect the water and create a high conductivity. The conductivity of distilled water is 0.5-3 Ohms. The reading the voltage meter gave us was a 84 Ohms, this is considered to be very conductiv... ... middle of paper ... ...Cooperative
a German chemist, improved Oersted's process by using metallic potassium. He was the first to measure the specific gravity of aluminum and show its lightness. In 1854 Henri Sainte-Claire Deville, in France, obtained the metal by reducing aluminum chloride with sodium. Aided by the financial backing of Napoleon III, Deville established a large-scale experimental plant and displayed pure aluminum at the Paris Exposition of 1855. Aluminum is a lightweight, silvery metal. The atomic weight of aluminum

In this paper, a synthesis of Jacobsen's
I chose to do the effects of different disinfectants on bacteria because I have always wondered if disinfectants such as Clorox, Lysol, and hand sanitizer actually kill 99.9 percent of germs. Also, I know that there are harsh chemicals that can be damaging to us over time. Do these harsh chemicals get the job done? Maybe taking a green, organic way could be the solution in the future. My main question is which is the better disinfectant, Clorox Disinfecting Wipes or Lysol Disinfecting Wipes. I want
