In the demo experiment, we placed 10 grams of Ammonium dichromate in the form of a solid before starting the experiment. When the experiment begins the Ammonium dichromate is burned up and then produces Chromium (III) oxide as a solid, Nitrogen gas and water in form of a gas. In the experiment, we combined Zinc Chloride and Sodium Sulfide in which both chemicals are aqueous. The result of the combination was Zinc Sulfide a solid and Sodium Chloride an aqueous solution. In the alternate experiment, we combined Lead (II) Nitrate and Potassium Iodide in which both chemicals are aqueous. The result of the combination was Lead (II) Iodide and Potassium Nitrate.
To see a chemical at a microscopic level you would need to use a microscope versus the macroscopic level in which you can see with the naked eye. In the chemical equation (NH4)2Cr2O7(s) ——> Cr2O3(s) + N2(g) + 4H2O(g) you will be able to witness it at a macroscopic level. In the chemical equation of ZnCl2(aq) + Na2S(aq) ——> ZnS(s) + 2NaCl(aq) you will be able to witness the solid at a macroscopic level and after separating the sodium chloride from the water you will also be able to see it at a microscopic level. In this chemical equation Pb(NO3)2(aq) + 2 KI(aq) ——> PbI2(s) + 2KNO3(aq) you will be able to witness the solid at a macroscopic level and after separating the potassium nitrate from the water you will also be able to see it at a microscopic level.
The reactant of the demo experiment is (NH4)2Cr2O7 in which it has a molar mass of 252.06 g/mol. The products of the demo experiment are Cr2O3 that has a molar mas of 151.99 g/mol, N2 that has a molar mass of 28.01 g/mol and 4H2O that has a molar mass of 72.08 g/mol.In the experiment the reactants are ZnCl2 that has a molar m...

... were of a solid and aqueous solution. For the alternate experiment, the chemical properties were aqueous while the chemical reactions were of a solid and an aqueous solution. Another type of chemical combination that could make a similar reaction like the first experiment is the alternative experiment. While the alternative experiment had other chemical combinations it will still create a similar reaction like the original experiment. The demo experiment was a good example of the law of mass conservation. The reason why is because while doing the experiment the chemical reaction caused the (NH4)2Cr2O7 to release a solid (Cr2O3), nitrogen gas and water in gas form. In which it proves that chemicals can not be created or destroyed just changed. A way in which it could be improved would be to find a way to measure the gas that is being released because of the reaction.

Chemical Reactions Of Chemical Kinetics Essay

- Chemical kinetics is a branch of chemistry which refers to chemical reactions with respect to reaction rates, effect of various variables, re-arrangement of atoms, formation of intermediates and much more (Chung Chieh, 2016).The importance of chemical kinetics is that it provides evidence for the mechanisms of chemical processes and provides a very detailed description of what happens to each molecule —which bonds are broken and formed, and how the three-dimensional shapes of the chemicals changes during the course of a chemical reaction (Keith J....   [tags: Chemical kinetics, Chemical reaction, Chemistry]

The Reaction Of Chemical Kinetics Essay

- Objective: To calculate and find the reaction order by using the concentration of crystal violet. Introduction: Chemical kinetics is a branch of chemistry that involves reaction rates and the steps that they follow in. It tells you how fast a reaction can happen and the steps it takes to make complete the reaction (2). An application of chemical kinetics in everyday life is the mechanics of popcorn. The rate it pops depends on how much water is in a kernel. The more water it has the quicker the steam heats up and causes a reaction- the popping of the kernel (3)....   [tags: Rate equation, Chemical kinetics, Reaction rate]

Reaction Rates Of Chemical Reactions Essay

- Introduction Kinetics is the discovery and study of the reaction rates of chemical reactions. These reaction rates involve the pace or rate at which a reaction progresses. Many specific conditions can affect the reaction rate value; furthermore, the factors include the concentration of the reactants, the polarity of the solvent, and temperature1. The rate of reaction can be determined and studied using a rate law, an equation that correlates the rate with concentrations and a rate constant. This experiment’s reaction involving t-butyl chloride has a first order reaction rate, which means that the reaction’s rate law equation is the first order equation shown below....   [tags: Chemical reaction, Chemical kinetics]

Essay on Stoichiometry of a Chemical Reaction with a Gaseous Product

- Stoichiometry of a chemical reaction with a gaseous product. Introduction In an equation of compounds, the number before the formula mean the number of atoms of each element talking part in the reaction. These number are the coefficients, and they can also mean the amount of moles in the compound. The equation has to be balanced so the final product is stable and so the maximum amount of each product is formed. In the experiment the magnesium reacts with hydrochloric acid and it makes magnesium chloride and hydrogen gas....   [tags: Experiment, Magnesium]

Essay on An Experiment On Hydration Of Alkenes

- Hydration of alkenes is characterized by the addition of water and an acid-catalyst to a carbon-carbon bond leading to an alcohol. Dehydration is exactly the opposite in which dehydration of an alcohol requires water to be removed from the reactant. Equilibrium is established between the two processes when the rate of the forward reaction equals the rate of the reverse reaction. The alkene that is used in this experiment is norbornene. Through hydration of norbornene, an alcohol group should be present on the final product yielded what is known as exo-norborneol....   [tags: Chemistry, Chemical reaction, Ethanol, Acid]

The Gravimetric Stoichiometry Lab Experiment Essay

- The Gravimetric Stoichiometry lab was a two-week lab in which we tested one of the fundamental laws of chemistry; the Law of Conservation of Mass. The law states that in chemical reactions, when you start with a set amount of reactant, the product should theoretically have the same mass. This can be hard sometimes because in certain reactions, gases are released and it’s hard to measure the mass of a gas. Some common gases released in chemical reactions include hydrogen, carbon dioxide, oxygen and water vapor....   [tags: Chemistry, Chemical reaction, Heat, Water]
