Equations

Chemical change is any change that results in the formation of new chemical substances. Chemical changes take place on the molecular level. Another way to think of it is that a chemical change accompanies a chemical reaction. To find if a Chemical Change is occurring you need to determine whether a new substance has formed because of the change. If a new substance has been produced, then a chemical change has occurred. The new substance formed in a chemical change could be a solid, liquid or…

Aim: - The aim of this experiment is to find out on how the independent variable which is the temperature changes that reaction rate of the magnesium and hydrochloric acid (HCI). Hypothesis: - As the concentration increases, the rate of reaction increases as well. Variables: - The independent variable is the volume of hydrochloric acid - The dependent variable is variable is the volume of the hydrochloric acid and the duration of reaction. - The controlled variables are length of the strip of…

A short story by Tom Godwin called “The Cold Equations” interprets the theme life isn't always fair. This story takes place in the year 2178 and is about a girl, Marilyn, who stows away on a space craft called “Stardust.” The girl get's caught because of the heat radiation from her body. She is told about the rules and how she would have to be killed, because the craft has only a certain amount of fuel to get from point A to point B. She had no idea of the rules, and was only trying to get to…

All the scenes in the play were short and barely any characters were called by name. They also did not go in order of the pamphlet that spells “Shakespeare.” Throughout my paper, I try to describe each scene to the best of my ability with the info of which play they are acting out or about just the scenes in general. The beginning of the play began with people cleaning up the stage with brooms. The three people were slouched over sweeping close together. This showed medium topography and close…

Introduction This extended experimental investigation (EEI) investigated the effect in which concentration had on the rate of reaction. The purpose of this experiment is to test different concentrations of hydrochloric acid with sodium thiosulfate and to see how long it would take until the cross underneath the flask is no longer visible through the milky white solution. Collision theory A collision is when two or more object run into each other. But collision theory is, that only some…

The aim of this experiment was to build a shake torch and measure the electrical voltage produced when the magnet passes through a coil of wire. Our dependent variables were the amount of magnets (length of magnet) and the amount of shakes. This was done to help us discover if there was a relation between the amount of magnets, and the induced current produced. It was to investigate if a greater magnetic field and increased amount shakes would improve the shake torches ability to light the LED…

4.2 Resources CO2 Fig.1 depicts the principle of chemical energy transmission system. Fig.2 explain the Eva-Adam process. 5. Thermodynamics of CO2 reforming of methane It is essential to understand the thermodynamic of CDRM represents as follow: CH_4+CO_2 □(→) 2CO+〖2H〗_2 ∆H_298=247 KJ⁄(mol ) (1) ∆G^o=61770-67.32 T This reaction above is highly endothermic which is favored by low pressure but, requires a higher temperature. A reverse…

3.2 Effects of particle size The particle size of the catalyst was highly influenced on the reaction rate, when the particle size of the catalyst was decreased, therefore their surface areas was increased and the ratio of catalyst surface and reactant volume was playing a crucial role for controlling the reaction kinetics. The reaction was takes place on the surface of a substance, increasing the surface area should increases the quantity of the substance that is available to react, and will…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…

The writing process is both complex and interesting at the same time. There are many ways to write and the process is different for everyone. In this essay, I will explain my found writing process and analyze my process alongside Peter Elbow’s Teaching Thinking by Teaching Writing, Alvarez’s Writing Matters, and Stafford’s A Way of Writing. My first step in writing begins with choosing the right location. Usually I choose my office or bedroom, but sometimes when I stick to a routine, I become…
