Investigating the Properties of pH The manufacture’s claim is that Sensodyne toothpaste micro hardens tooth enamel to help protect against the effects of acid wear‚ helps stop the twinges of pain from sensitive teeth formulated with low abrasivity‚ neutral pH and gentle yet effective cleaning system. To find out if the manufactures claim on Sensodyne toothpaste is the correct level of pH. I expect the Sensodyne toothpaste to be a neutral pH level as the manufactures claim that this products

Physical and Chemical Properties Chem 107 6-4-2013 A pure substance or chemical substance is a material that is homogeneous. It has consistent properties throughout the sample.” Pure substances can be described by both physical and chemical properties”. Physical properties can include‚ color‚ odor‚ melting point‚ boiling point‚ and solubility in various solvents‚ etc. The observation of these physical properties does not involve any chemical change in the substance‚ it is still the same

In order to develop Realtors as a Real Estate company‚ a task was assigned to propose a plan for a Property Management department which is set to be opened in Realtors Czech Republic. This plan‚ if accepted‚ would possibly be established in other Realtors international branches in Spain and Slovakia. To accomplish this assignment‚ I held a thorough research and constantly re-designed and perfected my proposals‚ about five weeks in total. This memo presents the finalized design of the department

Department of Chemistry [Colligative Properties & Osmotic Pressure] Purpose : The experiment this week had two different purposes. The first is to teach us about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis

Luya or Ginger is widely distributed in the Philippines. It has a very aromatic rootstocks that contains active constituents like zingerone and shogaols that are responsible for pungent properties of ginger. But mostly of the therapeutic use of ginger are found on its rhizome. Gingerol is one of the active constituent that exert its antimicrobial effect.

Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body‚ following a curved path‚ has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum. Torque is the angular "version" of force. The units for torque are in Newton-meters

Physical Science Part A a) Materials A material is something which an object is made of. There are different types of materials and each type has its own properties. Materials can be natural or man-made. Natural materials can come from animals‚ plants or the ground. Man-made materials are artificially made using chemicals. There are different types of materials. Examples: Wood Rubber Cloth Metal Rock Plastics Glass Wood: Wood comes from trees. Wood can last
