Chemical decomposition

that measures the quantity of chemicals in a reaction. This branch relies heavily on moles and balancing. A mole is a unit of measure for giant quantities. It is a number of atoms or molecules that is so large that it is only logical and convenient to use it for atoms and molecules. One mole is 6.02 x 1023 atoms or molecules. We call this Avogadro's Number. Furthermore, balancing chemical equations is the process of changing determining the coefficients in a chemical equation, making sure that…

students used enzymes as catalysts in order to speed up the reaction processes involved in several tests. Enzymes are substances produced by living organisms that act as a catalyst, while a catalyst is a substance that increases the rate of the chemical reaction. Furthermore, varying amounts of pH and enzymes were added to the mixture in order to determine the substance’s rate of reaction. When the reaction occurs, students are supposed to study and observe it until the substance becomes…

There are five common ways to predict the product of chemical changes. They are synthesis (composition), decomposition, single replacement, double replacement, and combustion. Each can be used for different types of problems based on the equation of experiment presented to you. They can also be found using observations throughout the experiment. You use these base guidelines to write a well balanced equation with physical states and all of the reactants and products that are produced. Our…

This experiment demonstrates how the results of two reactions can create a colored flame with the sugar in the gummy bear. When potassium chlorate is heated to its molten state, it goes through a thermal decomposition reaction that causes it to dissociate into potassium chloride and excess oxygen. The gummy bear is mostly made up of sugar and causes a combustion reaction when mixed with the excess oxygen. Carbon dioxide and gaseous water are released as a result of the reaction. The purple…

equations helps us mathematically see what is happing during the reaction besides performing and watching it occur. Being able to identify the limiting reagent, products produce, and solve for molarity is key to chemical analysis. Performing the experiment is just half of the equation in chemical analysis. This lab did not have many safety precautions except there was an open flame…

Stoichiometry is known as the quantitative relationship between various products and reactants in a chemical reaction. There are many ways one can stoichiometry in his/her advantage. If you start off with a known amount of reactant, stoichiometry can definitely be used to make a prediction to the amounts of the future product that will be formed. And in the other side, if you has a desired amount of product want, you can use stoichiometry to predict of on how much reactant you will need to…

different types of chemical reactions such as double displacement, single displacement, decomposition, and synthesis reactions were observed. During the lab there 4 stations A, B, C, and D each letter has two different options to choose from. The students job is to choose the option that will create reactants that reach the standards for the reaction to be considered safe. The purpose of this lab is to give students a better understanding of chemical reactions, how to identify if a chemical…

Introduction: Chemical reactions are a process that involves, rearranging the molecular structure of substances to create new ones. There are 3 types of chemical reactions, firstly there's synthesis, (e.g. 2Na + Cl2 → 2NaCl); then, the other type of reaction is decomposition (CaCO3 → CaO + CO2); and finally there is combustion. Combustion is a rapid chemical combination of a substance (fuel) with oxygen, including the production of heat and light (e.g. CH4 + 2O2 → CO2 + 2H2O). In these types…

to the heated substrate surface as in of chemical vapor deposition as shown in fig. Droplets after collision with heated substrate changes into powdered form. The droplets closer to the heated substrate but not in actual contact improves the efficiency of film growth (Perednis D.…

Chemistry is the study of atoms. Chemical scientists study what atoms are made of and how they connect. Atoms are the building blocks of matter. Atoms are made up of protons, neutrons and electrons. It was John Dalton who put forward his ideas and theories about atoms at the beginning of the 19th century: Dalton proposed that atoms were like tiny, hard balls (Absorb Learning, 2008). Then at the end of the 19th century JJ Thompson discovered the electron through an experiment. When JJ Thompson…
