LAB REPORT ON VERIFICATION OF HESS’S LAW Our purpose of doing this lab was to prove the Hess’s law correct. Hess’s law suggests that the enthalpy change of a reaction must be equal to the sum of the enthalpy changes of the related reactions which lead to the original reactions. The following are the reactions at the lab; 1) NaOH ( s) NaOH (aq) 2) NaOH (aq) + HCl (aq) NaCl (aq) + H2O (l) 3) NaOH (s) + HCl (aq) NaCl (aq) + H2O (l) As explained before‚ Hess’s Law states that the enthalpy

There are many energy sources that can be readily converted into electricity. In Australia‚ most power plants burn a fuel‚ such as coal‚ or use the energy of falling water to generate electricity on a large scale. Electricity is also relatively

Madeline Totten Dr. Su Phy 110 Lab 18 September 2013 Lab 2: Introduction to DataStudio Purpose: The purpose of this lab is to practice designing an experiment by choosing the variables‚ using DataStudio to collect the data from the experiment‚ and then taking our data and presenting it and our results in a report. Method: For this experiment‚ the goal was to use a simple pendulum (shown to the left) to measure the period of the motion. For task 1‚ we just became familiar with DataStudio

What is Physics? Physics is a field of science that shows the interaction between matter and energy. It shows physical processes that help us understand better how our universe behaves. Physics also use scientific method that formulates and tests hypothesis which are based on observations and comprehensions. What are the different fields under Physics? PHYSICS PHYSICS dealing with physical processes and their relations in the science of physical chemistry. dealing

Finding the rate law was the overall goal of the laboratory. When finding the wavelength of the Azo Orange II dye‚ the highest wave was the point used‚ 483nm. The plotted points of the different concentrations absorbance’s made sense to have a steady upward slope because the dye was diluted in steady increments from full to ¾ and so on. Beer’s law was used next to calculate the absorbance of they time over time as bleach was added. One the absorbance value was calculated‚ the concentrations were
