Solubility‚ Crystallization and Melting Point Determination Post-Lab Discussion Guidelines: Part 2A and 2C: Draw tables (as in textbook) showing which combinations were soluble/miscible and which were insoluble/immiscible. Explain why this is so. Why are certain chemicals soluble/miscible when others are not? Part 3A: Calculate % recovery (this is not the same as % yield – see handout from the first day of lab if you’re confused)‚ and determine melting point of your product. Discuss % recovery

Lab 2 Physics 190 Acceleration “g” Due to Gravity – Method 2 Introduction Tonight we will measure the acceleration due to gravity again. This time however‚ we will collect more data and the analysis will be different. We will first fit the data using a second order polynomial. Recall for a mass falling from rest‚ that 1 (1.1) y a yt 2 2 Suppose a mass falls through n successively greater displacements‚ each time starting from rest. The displacements can be expressed a 2 y y t ;

Kalle Watts Measurement Lab 9‚ 27‚ 2012 In this measurement lab we attempted to make the most precise and most accurate measurements. We used the materials and equipment that we had to make all of our measurements. We had to deal with significant figures and also‚ we had to designate each measurement with its proper unit. The objective of this lab was to use all of our equipment we had and make the most accurate measurements

Saliva Lab Since the amylase enzyme is present in saliva‚ starch digestion begins in the mouth. Salivary amylase changes the polysaccharide starch into many disaccharide molecules of maltase (a simple sugar) which are further broken down into glucose units by maltase enzyme in the As stated above‚ saliva contains the amylase enzyme which begins the breakdown of starches. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under
