Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water

July 28st‚ 2014 Lab #10 Properties of Light Purpose: The ideal purpose of this lab activity is to investigate the relationship between the frequency of the light (color) and the energy produced by different colors of light. Other purposes of this experiment include calculating the proper current for each LED‚ measuring the evaporation rate of rubbing alcohol‚ and being able to discuss the outcome of the relationship in light energy and the color of the light producing the energy.

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Cognitive Properties Ashley Weber Principles of Chemistry 2 Experiment 1 02/02/2015 Abstract: Several experiments were performed to observe the colligative properties. This includes the freezing point depression‚ and osmotic pressure. Two ice baths were made‚ one with pure water‚ the other with salt water. The lowest temperature was then record for each bath and compared. The salt water had a lower freezing point than the pure water by 2 degrees which supports the hypothesis that solutions have

this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs and circuits (from previous lab) * Pipette (or eyedropper) * Rubbing

Exercise No. 2 COLLIGATIVE PROPERTIES (Full Report) I. INTRODUCTION Colligative properties In liquid solutions‚ particles are close together and the solute molecules or ions disrupt intermolecular forces between the solvent molecules‚ causing changes in those properties of the solvent that depend in intermolecular attraction. For example‚ the freezing point of a solution is lower than that of the of the pure solvent and the boiling point is higher. Colligative properties of solution are those that

The Justification of Private Property Property Law JURI 25066EL Ryan Waschulzik 0271075 March 4th 2015 Words: 1772 Pages: 8 The notion of property is one that has long preceded us‚ or anyone we know. We know that the earliest social theory of property originated in the works of Saint Thomas Aquinas who had said that humans have a natural right to the use of or ownership of an unspecified amount of property. He also said that the amount of property to which you are entitled‚ is based
