Les Misérables (Reaction Paper) Les Misérables (the musical) in my opinion is one of the best musical renditions in the world. Whether it’d be in the theatre or on the big screen‚ Les Misérables‚ never cease to deliver such a heartfelt act. A few weeks ago‚ I was given the chance to watch the recent Les Misérables musical in the movies (starring Hugh Jackman‚ Anne Hathaway‚ Russell Crowe‚ and Amanda Seyfried) and I enjoyed it. Im a person who loves music. I most definitely love musicals! The

Chemistry Lab Report Jeffrey Kenneth Bangero Introduction Firstly we calculated the mass of the beaker and then we put the assigned grams of sodium carbonate and calcium chloride. Then we add 50 ml of distilled water to each substance‚ sodium carbonate dissolved faster than calcium carbonate. After we mixed both sodium carbonate and calcium chloride and they form a solid precipitate. Then we poured it a funnel with a filter paper to get the solid precipitate. Purpose ● The purposed

Chemestry Lab Rates of Reaction (Picture from: http://sciencespot.net/Pages/kdzchem.html) The rate of reaction is how fast or slow a reaction is completed. This is important for factories and chemists all over the world. What happenes during a reaction is atoms or molecules that collide and form new molecules. You can affect this rate of reaction with: temperature of reactants or suroundings‚ surface area of reactants‚ if there is a catalyst present‚ but in theis lab the concentration was changed

Managing the External Environment: A Reaction Paper The report that was presented by the reporter‚ Arlo Ramos was indeed very comprehensive and informative. I agreed on almost all points on the report especially on how external environment will greatly affect the trend of the business‚ how these external factors play a very important role in deciding the future of the business and its complexity representing both threats and challenges if not mitigated properly and even potential possibilities

Introduction: A balanced chemical equation has reactants and product that has to represent a formulae. The amount of each element‚ number needs to be the same in either side of the equation. (E.g.‚ HCl(aq)+NaHCO3(s) reacts to produce NaCl(aq)+H2O(I)+CO2(g)‚ this is the equation given for this lab). This help us view the study of Law of Conservation of Mass‚ when either side of equation is equally balanced. The calculation for formula mass helps determine if you need to convert grams to a particular substance

How much is it? How does reaction time change with practice? THEORETICAL The reaction time is the amount of time required to sense astimulus‚ analyze its meaning‚ and respond. Acceleration is the rate of change of velocity. Velocity is speed with direction

Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element
