Impurity Lab Report Aim: To find out the difference of the boiling point and melting point when adding impurity (salt) to water. Diagram: Method: 1.Set up the apparatus as shown in the diagram 2. Get a known amount of ice in the beaker (half full)‚ and a known amount of salt in another beaker 3. Measure the temperature (melting point) of the ice without adding any impurity (salt). 4. Measure the temperature (melting point) of the ice after adding the salt into the beaker. 5. Heat up

The charges move until the potential across the capacitor plates is equal the potential between the battery’s terminals. Then the current ceases and the capacitor is fully charged. R R C C Fig. 1.

Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

“demand curve”. (b) Assess what information may be helpful to the strategic marketer in order to determine demand. (c) Discuss the factors that may create a fluctuation in demand. The demand curve is the graph depicting the relationship between the price of a certain commodity and the amount of it that consumers are willing and able to purchase at that given price. It is a graphic representation of a demand schedule. The demand curve for all consumers together follows from the demand curve of every

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

The LM curve represents combinations of interest rates and income levels that result in equilibrium in the money market (money supply money demand)‚ for given M/P. The IS curve represents combinations of interest rates and income levels that result in equilibrium in the goods market (investment saving)‚ for given T and G. 2. Equilibrium must be at the ISLM intersection; only at that point does investment equal saving and the money supply equal money demand. At a point on the IS curve and to

forests‚ and other natural resources. Even as early as the middle ages‚ farmers in the East and what would become South America realized the need for crop rotation to prevent soil erosion. In Europe‚ the plague prompted improvements in the public health system‚ particularly to improve the water. Also‚ due to Englanders nearly depleting all of their forests‚ they switched to coal—a resource that would later cause many more health problems‚ especially in the larger cities. Beyond that‚ as health problems
