Shanel Warren Tiffany‚ Princess‚ and Wei October 2‚ 2013 Determining the Mole Ratios in a Chemical Reaction Introduction The purpose of this lab was to determine the mole ratios of the reactants hypochlorite ion (OCI ) and thiosulfate (S O ) when reacted in a chemical reaction. A chemical equation gives the mole ratios of the reactants and products involved in the chemical reaction. When some formulas of the products are not known‚ experimental measurements can be made to

Formula One In May 2009 Max Mosley‚ then President of the Federation Internationale de l’Automobile (FIA)‚ declared that “the sport could survive without Ferrari.”1 Incensed by such brazen disregard of the team’s influence and further angered by proposed changes to the competition’s format‚ Ferrari announced that it did not intend “to enter its cars in the next Formula One world championship.”1 By June‚ eight of the ten F1 teams had declared their intention to join Ferrari’s breakaway championship

The amount of a certain type of substance‚ in mole that can be calculated accurately from their mass are called primary standards due its purity. Primary standards should be always readily obtainable in pure form. It also should also have a known formula and be simple to put away without deteriorating or reacting with the atmosphere. It is also preferable that the substance have a high molar mass in order to decrease the effect of errors in weighing. A primary standard can be used to prepare a standard

Empirical Rationalism claims that it can be clearly observed that a person’s moral judgements come directly from his or her rational capacity. In other words‚ it claims that based on observation‚ it is evident that our moral judgements come from reason. This opposes to sentimentalists’ theories which claim that our moral judgments come from our emotions. Shaun Nichols affirms that research done on psychopaths proves empirical rationalism wrong. For example‚ he states that psychopaths’ ability to

Chemistry Lab Report Determining Best Calorimeter Dylan Mendonca 12-B Background: Calorimetry is the science of measuring the heat of chemical reactions or physical changes. Calorimetry is performed with a calorimeter. A calorimeter can be any container from a cup to a Calorimeters need to be well insulated as calorimetry relies on the fact that temperature change only occurs within the solution and that no heat escapes to the surroundings. That is why it is important that calorimeters are well
