A blacksmith is in the process of making iron horse shoes. Each shoe, mass of 255.15g, is heated to a bright red (816c), hammered into shape, and then dropped into water to cool. If the bucket contains 4L of water (4000g) initially at room temperature (23c) what will the final temperature of the iron be? Specific heat of cast iron: 0.461 J/gC. Specific heat of water: 4.18 J/gC

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
