Lab Report For Energy Experiment

Determine the energy per gram (kcal/g) that is estimated on the package for each food

The independent variable in the experiment was the mass (or amount) of the cheese and bacon balls.

2. Four unknown samples were included in the lab kit: flax seed meal, potato starch, egg whites, and dried milk. Using the results of the biochemical testing, determine which number corresponds to the correct unknown. (8 points)

Aim: To plan, conduct, evaluate and report on an investigation of chemical changes, and make recommendations for their use as an energy source in Heat-and-Eat meal packs.

To make the results of the experiment valid four variables to take into account are if the freezer is the same temperature for both tests, the water is the same water just different temperatures, the ice cube trays are the same size, and finally both trays are in the freezer for the same amount of time.

The independent variable in this lab is the molarity of sucrose each dialysis bag is filled with. The time (30 minutes), the temperature (23C) and the type of dialysis tubing used are all constants.

Mass of water x 4.2 (water’s specific heat capacity) x temperature change = energy transferred from the fuel to the water

Twenty years have passed since the implantation of the North American Free Trade agreement. While it has changed Mexico in some fundamental ways, the treaty never met many of its extensive promises to close Mexico 's wage gap with the United States, boost job growth, fight poverty, and protect the environment. The hope was that freer trade would bring stronger and steadier economic growth to Mexico, providing new jobs and opportunities for its growing workforce and discouraging illegal migration from Mexico. With modernizing the Mexican economy so that it would export goods, not people. Mexico’s people feel as though NAFTA’s pledge has created a loss of national independence and a narrow income gap.

The temperature of the water that the test tubes sit in is another controlled variable. This is because temperature is known to affect rate of fermentation. This can be controlled by using the same water bath to heat all 6 test tubes.

4. Remelt the contents of the tube and add the counterpart component based on the given schedule. Ask the demonstrator to adjust the cooling water between mixtures. During the experiment, record and plot the data obtained for all mixtures listed. The experiments are stopped as follows:

Has the death penalty become non-effective? For centuries, death has been viewed as the highest form of capital punishment. However, this is strictly dependent on the idea of equivalent exchange. Ideally If a person causes death, in return, they deserve death as well. However, this ideal does not compensate for the pain and suffering that is forced upon the friends and family of the victim. Death is not the only circumstance we must consider. The distress that is forced upon the families of the victims cannot be compensated by simply sentencing the culprit to death. This base ideal of equivalent exchange overlooks these circumstances. On top of this, the judicial system has a very common problem with sentencing innocent people to death. Is this really social justice? Not only do studies show that this form of capital punishment been has proven as overall non-effective; furthermore, judicial inaccuracy has only contributed to the continuation of pain among societies.

Islamophobia is well and alive in the United States of America. Many people would argue that Islamophobia is non-existent and a myth. It would be wonderful if it was indeed pure fiction. Sadly, this is a concern that is evident not only here in the U.S. but places around the world as well. Places such as France, the United Kingdom, and even Latin America. Whether one chooses to admit it to themselves or not, the fact is that there is a fear towards Muslims in this country and it is detrimental.
