Purpose Determine the ratio of sugar to corn syrup that produces the best-tasting and best-textured marshmallow. Hypothesis That marshmallows will taste better when made with more corn syrup than more of granulated sugar. I think this because the Materials Square or round foil cake pans, 8 or 9 inches wide (9) Masking tape Pen or permanent marker Vegetable oil, like canola or safflower oil, for greasing pans Paper towels (1 roll) Powdered or confectioners sugar (3 cups) Strainer, small…

hydrocarbons with over twenty are solid. Error occurred in experiment one because my lab partner and I were both in charge of reading and recording the temperature of two thermometers at the same time. This means that we checked one before the other every single time we took measurements. The reading of our second thermometer was especially delayed if the first temperature was difficult to determine. This would have made the first temperatures we read, water and hexane delayed by a few…

6 cleaned and dried conical flasks were collected and safely transported to the experimental table. 2. A black marker was used to mark a black cross on a white sheet of paper. This was to help with measuring the time (dependent variable). 3. A thermometer was placed on the table to measure the room temperature. 4. 0.15mol/L sodium thiosulphate solution (Na2S2O3) and 3mol/L hydrochloric acid (HCL) were poured into two separate 50 ml beakers, and the two beakers were transported to the…

Introduction The purpose of this lab is to find the most efficient way to capture energy from a combusted chip using a calorimeter. We made a basic calorimeter by using a steel can. Through out our lab we made modifications to the calorimeter to increase the percent of energy captured by the water. Literature Review Kinetic energy is the energy of motion. The kinetic energy of an object is energy that is being used. Potential energy is stored energy that it is not in motion, but has…

Pour Ice into a beaker. Place the piece of paper over the beaker so the circles are centered over the beaker and let the beaker and paper for 5 minutes so the the paper cools off. Using the thermometer, measure the temperature of the paper and record the result. Place a maggot inside the smaller circle and start the Stopwatch. Replace the remaining maggots in the refrigerator quickly to prevent them from warming up. Observe and record how long…

In today’s society, the use of technology has been becoming more and more recent. Lots of people, including parents and children of all ages are getting involved with it. Parents are starting to lose touch with reality with their own parenting. The question is, who’s more powerful? Technology or parents? It all depends on how you look at it. Technology is becoming more powerful and parents don't see it happening. According to Jim Taylor Ph.D., author of “Parenting: Who is More Powerful:…

prevented the care manager from performing the task. Jache was able to notice that the resident felt uncomfortable with the temporal thermometer. At first, Jache suggested the use of oral thermometers however, I informed her that oral thermometers were currently inaccessible. Jache was able to calm the resident by demonstrating to the resident the use of the temporal thermometer on herself and explained that it was only going to be in her ear for a short moment. Jache was able to measure the…

ABSTRACT Within this experiment, the use of a bomb calorimeter was required in order to determine the heat capacity of the system through the combustion of three separate trials of benzoic acid. The resulting heat capacity values for each trial were averaged, with a standard deviation found as well. This was then used to work backwards, for a naphthalene trial, in order to calculate the change in energy (∆U) and the change of enthalpy (∆H). The accepted value for the change in enthalpy of…

density, which will help us determine the molecular weight of the unknown. The necessary tools that are essential in this experiment include: a balance, watch glass, two pieces of foil (2.5x2.5 inches & 3x3 inches), boiling chips, a ring stand, a thermometer, a bunsen burner, and an 800mL beaker. During this experiment, we have to be cautious when removing the beaker because it can be hot, so we have to be patient in letting it cool off. Additionally, not only do we have to be careful around the…
