Objective To determine soluble solid concentration in some fruits including tropical and temperate fruits by using handheld refractometer. Introduction “Sugar are the major soluble in fruits juices and estimate of sweetness. Other soluble materials include organic and amino acids‚ soluble pectins‚ and others. Soluble solid concentration can be determined in a small sample of fruits juice using a hand held refractometer. The measurement must be made at 20°C to get an accurate value. This instrument

For instance‚ one who comes from hardship certainly can work through and excel in a way some call unbelievable due to grit. A passionate individual who stays committed to a long term goal will not have things handed to them by chance‚ but will work hard to achieve challenging goals. By being steadfast‚ one’s tenacity is admirable especially when becoming triumphant against all odds. As Angela Duckworth‚ professor of psychology‚ states in her best seller Grit‚ “The highly accomplished are gratified

search- specific latent heat Q. Value for the specific latent heat of fusion of water: Specific latent heat is where the amount of energy (in joules) needed to change the state of 1Kg of a substance is called its specific latent of heat. You can calculate the amount of energy needed using the equation: energy (J) = specific latent heat (J/Kg) X mass (Kg) Material Specific heat of fusion (J/Kg) Specific latent heat of vaporisation (J/Kg) Water 334000 2260000 Lead 24500 871000 Ethanol

Henri Murphy Mr. Dietrich English 101 29 Aug 2014 Determination I have been in school for twelve years and seen many friends drop out. I’ve never understood how they could make it so far and just give up. But the only thing that seems to make any since is a lack of determination. It is very good to have vivid image of the things you want in life. A lion doesn’t hunt its prey with its eyes closed so don’t blindly chase after a dream or hope to accomplish something without putting any effort

were conducted to find the specific heat of a metal as well as the heat of solution of a solid. Both experiments required the use of calorimetry to measure heat flow and temperature change. The specific heat of the metal was found by heating it in boiling water before transferring it to the calorimeter that was partially filled with water. After shaking the calorimeter‚ the temperature change was measured and recorded. This information was used to calculate the specific heat. The heat of solution

Tom Tribal Economic Development Midterm March 1‚ 2010 1. Define what is tribal “self-determination”? Discuss how “self-determination” has influenced economic growth in the modern tribal economy. Tribal self-determination was a way to better life for American Indians. Three main factors were put into place to help American Indians with the self-determination act. The first one is tribal self rule. A second factor would have to be cultural survival. Finally a third factor

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often
