Research This project is about what makes bouncy balls bouncy. My hypothesis is that the borax is what makes it bouncy and It will take more borax than glue to make the ball bouncier. This is important to know this because if you add too much or too less you will not have a real bouncy ball . There are three main thing we have to remember while doing this project. I will be mentioning three thing in my S.A.:Materials, Momentum, and Velocity. To make the bouncy ball bouncy it will need the…

ssment Page 42 1. Two categories that are used to classify properties of matter are extensive and intensive. 2. All samples of a given substance have the same intensive properties because every sample has the same composition. 3. The three states of matter are solids, liquids, and gases. 4. Physical changes are grouped into two categories known as reversible and irreversible. Reversible changes are changes from one state to another. Irreversible changes are changes that cannot change from one…

The scientist I chose to write about is Robert Boyle. I will be telling you all the important facts that happened in his life time. I will tell you when he was born and when he died. I will also tell you where he was born and in where at. Also who his parents were and if he had and siblings. I will try to tell you all about Robert Boyle's life. Like what discoveries he made, tell you how he's important, and how he became known. Robert Boyle was born January 25, 1627 in Lismore, County Waterford,…

Sir William Ramsay and Morris Travers founded neon in 1898, by experimenting on liquid air. Prior to discovering neon they had recently found krypton, then later on they would go to discover xenon. “ Ramsay knew that sometimes one element could stay hidden behind another element (Stewart www.chemicool.com/elements/neon.html).” Neon was actually named by Ramsay’s son and was named neon after greek words neos (which means new). After Ramsay and Travers were able to keep finding neon it opened…

This lab was conducted to find the key differences between the quantity of heat (q) and ∆H of a substance. Different masses of substances CaCl2 and NH4NO3 were dissolved in water to see how changing mass impacts the q and ∆H of a substance. When the two substances dissolve, they become ions. CaCl2 dissolves in a reaction of: CaCl2 Ca2+aq + 2Cl1-aq while NH4NO3 dissolve in a reaction of: NH4NO3 NH41+aq + NO31-aq . As shown in these reactions, when ionic compounds dissolve in water, they break…

Methods: To begin, our group acquired three premade vials of .1ml mammal blood with coagulant. We then labeled the vials numbers one, two, and three. In vial number one we added 1 ml of Stock 300 mM NaCl, and no distilled water. This resulted in a NaCl concentration of 1.8 percent. In the second vial we added .5 ml of Stock 300 mM of NaCl, and .5 ml of distilled water. This resulted in a NaCl concentration of .9 percent. In the third vial we did not add any Stock 300 mM of NaCl, and 1 ml…

I decided to pursue this degree because my first chemistry teacher inspired me. She is an amazing woman. Previously she had the job that I would eventually like to have and has a family, productive life, and also able to maintain all of her hobbies. I want to pursue this degree because I want to have a successful life like hers. I also want this degree because I love chemistry I believe that chemistry is my true passion. I have loved chemistry from the moment I started it. I wish to pursue a…

The purpose of the whole lab is to use my knowledge of the periodic table to determine the identity and physical properties of each unknown element. To find the unknown elements we looked at the characteristics of the other elements and grouped the ones that were similar and belonged in the same column. By looking at the characteristics of the unknown elements if it seemed to belong in a group with others with a blank we assumed it belonged there. Mendeleev was a scientist who came up with the…

Goals The goal of the lab was to investigate the properties and structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the…

chemist from Russia who lived in poverty and was the only one of seventeen siblings to attend school. Mendeleev then created the first periodic table from his finding through periodic law, which he also created. Medeleev was a major contributor to chemistry through the modern…
