Titration Lab Introduction The purpose of this lab is reach and be able to calculate the equivalence point when we use titration to neutralize a base with acid. The process of the lab was determining the volume of a solution needed to react with a given mass or volume of a sample is called titration. The equivalence point is when the same number of moles of acid and moles of base has been added. Phenolphthalein is used as an indicator because it will have a color change when the equivalence point

Calorimetry Lab Report Waris Butt PHY 112 Mr. Fasciano Class #18336 06/08/14 Purpose: Heat flow will occur between objects in contact until no more heat flow is detectable. Using calorimetry to analyze heat flow quantitatively and the equation: Q = mc ΔT‚ to determine the specific heat capacity of an object and heat flow from or to an object; respectively. Materials: Circle K 44 oz Styrofoam cup with lid Large Plastic

Sahara Desert The Sahara Desert is the world’s largest desert area. The word Sahara comes from the Arabic word sahra’‚ meaning desert. It extends from the Africa’s Atlantic Ocean side to the Red Sea and consists of the countries of Morocco‚ Algeria‚ Tunisia‚ Libya‚ Egypt‚ Mauritania‚ Mali‚ Niger‚ Chad‚ and Sudan. It is about 5‚200 miles long. Overall‚ the Sahara Desert covers 3‚500‚000 square miles. The geography of the desert is varied. In the west‚ the Sahara is rocky with varied elevation

Food Deserts There is growing trend of cities across the United States that do not have access to food such as places in Buffalo‚ Baltimore‚ or Detroit. According to the USDA‚ a food desert is to qualify as a “low-access community‚” at least 500 people and/or at least 33 percent of the census tract ’s population must reside more than one mile from a supermarket or large grocery store (for rural census tracts‚ the distance is more than 10 miles). You can even look up a food desert locater

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation

1. 1. Describe the Rock Cycle. Be sure to include the different rock types and processes that occur within the cycle. Consider a hypothetical granite (igneous rock) and describe three possible pathways through the cycle. The rock cycle is a model which is telling people that the changes of the rocks that take place on the earth. The changes show how each type of rock is formed. These all changes make their own type of rock base on the weathering‚ heat or pressure‚ etc.…all the rock made of

The Effect of Concentration on Absorbance Background Information The purpose of the “Determining Solution ‘Concentration’ Using A Spectrophotometer” lab was to use a spectrophotometer to find the relationship of concentration and absorbance obeying the Beer-Lambert law‚ which states concentration and absorbance are directly related‚ to then further determine the concentration of three unknown solutions. With the assumption that the solutions obey the Beer-Lambert law it is predicted that as concentration

Osmosis Lab Research Question: In this lab‚ our goal was to look at the effects of different sucrose concentrations on osmosis in potatoes. Our research question was “How do the sugar levels affect the rate of osmosis in potatoes?”. Background Information: Solutions consist of solutes dissolved in a solvent. In all living organisms there are many different types of solutes including salts and sugars. The major solvent is water. There are different concentrations of solutes in various regions
