    Impact of Hydration on Physical and Mental Performance By Raeey Melaku. Introduction Our body has its own way of indicating when we need a certain aspect that is essential for us to live. For food‚ there is hunger. For urination‚ there’s the need to use the bathroom and in this case‚ for water‚ there is thirst. Water is by far the most essential nutrient in the world. We need water everyday. We can go up to three weeks without food and yet we can only survive three days without

    I am going to investigate the enthalpy change of combustion for the alcohol homologous series. I will investigate how alcohols with increasing number of carbons affect the enthalpy change when an alcohol goes under combustion. The energy that alcohols release when being used is called the enthalpy change of combustion. This is defined as "Standard enthalpy change of combustion‚ is the enthalpy change when one mole of a substance burns completely in oxygen under standard conditions (298K‚ 100 KPa

    This laboratory was performed to find the temperature change‚ heat of reaction‚ and enthalpy change for neutralization reactions. The temperature change was found by subtracting the initial temperature from the final temperature obtained. Heat of reaction is negative heat of solution. Heat of solution was found by using the formula qsolution = mCsΔT (m= mass; Cs= 4.184 J/g°C; and ΔT = change in temperature). The enthalpy change was found by dividing the heat of reaction by the number of moles of H2O

    DETERMINATION OF COPPER BY COMPLEXATION‚ SOLVENT-EXTRACTION AND SPECTROPHOTOMETRY ABSTRACT To determine the concentration of copper in an unknown solution by using copper complexation‚ solvent extraction and spectrophotometry. Standards are used to create a calibration curve and the unknown concentration of copper is then calculated by using the linear equation from the calibration curve. The concentration of copper in the unknown solution 201 was found to be 12.57± 0.25 μg/mL. INTRODUCTION Copper is an

    Copper Sun Compare and Contrast Essay The book Copper Sun by Sharon Draper is a realistic story about a slave girl named Amari. Amari was taken from her village when “milk looking” men came and attacked them. The men killed the old and the young. Amari’s parents and her brother were all killed. Amari was then taken to Cape Coast and that is where she met Afi. Afi is like a motherly figure to Amari. Amari was then put on the “Ship of Death”. They were on the ship for a long time. They landed on Sullivan’s
