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

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine

information. There are also new concerns about food safety due to increasing occurrence of new food-borne disease caused by pathogenic microorganisms. This raises considerable challenges‚ particularly since there is increasing unease regarding the use of chemical preservatives and artificial antimicrobials to inactivate or inhibit growth of spoilage and pathogenic microorganisms.(Arques et al.‚ 2008; Aslim&Yucel‚ 2007; Brandi et al.‚ 2006; Cushnie et al.‚ 2005). As a consequence‚ natural antimicrobials are

I am going to talk about how gold is made. I also noticed some physical and chemical changes happening in the video. My first Physical change I saw was when they drill in a certain spot‚ on the rock then they can put the pieces back together and pretend it did not happen because the molecules have not changed in the object‚ you are just breaking them into smaller pieces. So that is why it is a physical change. A chemical change I saw is when there is gold mixed with other materials like silver and
