Cadet Eric Wiggins Date: 18 September 2014 Course Name: Chem 100 Instructor: Captain Zuniga Section: M3A Identification of a Copper Mineral Intro Minerals are elements or compounds that are created in the Earth by geological processes. The method of isolating metals in a compound mineral is normally conducted through two processes.

The chemical elements are divided into two broad groups, the metals and the non-metals. In this experiment, you will examine some members of the metal group and identify similarities and differences in their physical and chemical properties. Metals are the elements that are found in the left of the periodic table with high electrical and thermal conductivity. Metals lose electrons to create positive ion charges. Metals have a unique shine, are prone to forming, have a high tendency to form cations, and combine with oxygen to give mostly basic oxides.

The three most important properties of a wave are the wavelength, the amplitude, and the frequency. The wavelength is the distance from one point on a wave to the next identical point on the next wave. The amplitude is the distance from a waves rest position to either the crest or trough of the wave. The frequency is a rate which represents the amount of times a wave repeats

In cycle one, the double displacement reaction, Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) occurred, the result of the reaction was that the reaction mixture began to bubble with the copper filling dissolving and a vapor like substance leaving the reaction. Furthermore, when water was added, the color change, from brown to a blue color pigment. Then in Cycle two, another double displacement reaction occurred, Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq), which resulted in the reaction becoming cloudy and a darker shade of blue. Following cycle two, a decomposition reaction occurred as the result of heat being administered to the mixture, thus the following reaction occurred in cycle three, Cu(OH)2(s) → CuO(s) + H2O(l). As a

Say, “Everyone come to the rug so you can watch another fun video about shapes. Today we’ll be working with squares and rectangles and their parts.” 2. Play the videos 3. Ask the students, “What are the parts of a square?

In "Passage 1: Sound is All around Us, Sound is Energy" Jason Torres claims that sound is a form of waves that vibrate in one directions called longitudinal waves. "The distance between two adjacent compressions, two adjacent rabout the longitudinal arefactions, or a single compression and rarefaction combined is a wavelength of a sound wave. " This is Jason Torres ' definition of Longitudinal Waves. The wave measures the sound and pitch. This pitch and sound can differ due to the extent of energy/waves released.

We had to do it on the computer and ad sound to it so it can be even more interesting. Finally we had to present it in front of the class. Many artifacts will represent several Student Learning Capacities. Explain how the attached evidence proves your achievement of the capacities that follow. Write about ALL that apply.

I will also provide flashcards of different words with /ch/, /th/ and /l/ sounds in them and then have the student read off each word. One idea I found was using the Sorry board game and use the flashcards as game cards. The student has to correctly say the word to move his piece. The words can get harder as the game progresses or as the student progresses in his articulation. The student can also bring home the books so he can practice on his own how to correctly articulate/pronounce the different words.

Standard N is connected to synthesis 3-4, because we wrote a story about a song that had to include all of the standards points. The assignment that I wrote was to write a story about a song of my choice so I had to create a setting, situation, problem, one or more points of view, and introducing characters. This standard helped me understand how to write correctly and to show my strong and weak points. Therefore, It will help me grow in my literary knowledge and my writing skills for a job interview. I think that I did fairly well on this standard, but I need to work on my punctuation skills, and my tense usage.

Many people do not realize that chemistry is a part of our day to day lives. One specific thing we see on a daily basis is the colors and paint people use in paintings, on buildings, and any other place paint could be. When this paint is developed, the people who make it have to decide exactly what the compound should be made up of. This is an important thing to consider when making these paints because as discussed in Chemistry 101 lab, compounds are different things that develop one item, in this case it is paint. They have to make sure that the paint is homogenous because if it was heterogeneous when being applied, the paint would not go on well.

Stoichiometry is a method used in chemistry that involves using relationships between reactants and products in a chemical reaction, to determine a desired quantitative data. The purpose of the lab was to devise a method to determine the percent composition of NaHCO3 in an unknown mixture of compounds NaHCO3 and Na2CO. Heating the mixture of these two compounds will cause a decomposition reaction. Solid NaHCO3 chemically decomposes into gaseous carbon dioxide and water, via the following reaction: 2NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g). The decomposition reaction was performed in a crucible and heated with a Bunsen burner.

A wave is a rhythmic disturbance that carries energy, not matter, through the particles of a medium, one of many aspects that make up what we call waves. A wave is made up of many parts. One of them is the medium. The medium is the material through which the wave travels.

Waves travel through medium or matter. When someone speaks, they send out a pressure disturbance in the air. You can also create a wave by using a rope or string. Use what you know about waves and energy to design and carry out an investigation that will allow you to describe the relationship between a wave’s energy and its amplitude, wavelength and frequency. How do frequency, amplitude, and wavelength of a transverse wave affect its energy.

The final acoustic attribute that defines the sine-wave tone is its starting phase. Thit does not mean that this phase is not encoded by the auditory system. As phase differences between the sounds reaching each ear result in differences in perceived location of the sound source. The two sounds differ in frequency, with the sound cycling between periods of higher and lower air pressure at a lower rate, or frequency. These physical properties influence how it is displaced by sound; higher frequencies vibrate the stiffer base to a greater extent than do lower frequencies, creating a place code along the basilar membrane such that different locations are maximally displaced by different sound frequencies.

There are many different waves. All of the waves can be measured just by amplitude, frequency,wavelength, and energy. Amplitude is how high or low the waves are. If you use energy like screaming the amplitude will create a higher frequency. Amplitude is the distance from one of the starting line which is the highest point of each wave.
