Across the period‚ the metallic character of the Period 3 elements decreases. This is evident as sodium‚ magnesium and aluminium‚ the first three elements in period 3‚ are all classified as metals. We observed that they display highly metallic characteristics‚ as they are all solid‚ malleable and lustrous. On the other hand sulfur‚ which is further along the period in group 16‚ is too a solid although it is quite brittle and in powdered form. It is a dull‚ pale yellow and does not possess the shiny

What kind of role does hydrogen peroxide and a liver have in their chemical reaction? In the experiment‚ we saw they had a reaction‚ but completed further tests to determine whether they changed after the reaction. Hydrogen peroxide is chemically changed into water and the liver is broken down in the reaction. In the experiment‚ a fresh piece of chicken liver was put into a test tube filled with 3% hydrogen peroxide. We knew a reaction was taking place because the hydrogen peroxide started to foam

CHAPTER 7 SPEED - Is a scalar -measures “how fast an object is moving” INSTANTANEOUS SPEED -the speed at any given instant in time AVERAGE SPEED -the average of all instantaneous speed; found simply by a distance or time ratio. SPEED= distance/Time TIME= Distance/Time DISTAnce= Speed*Time VELOCITY- is a vector Refers to the rate at which an object changes its position VELOCITY= displacement/time MOTION- is a change in position with respect to a reference ENERGY-

that Affect the Rate of Reaction of the Decomposition of Hydrogen Peroxide Emilio Lanza Introduction- In this experiment‚ the rate of reaction‚ calculated in kPa sec-1‚ of the decomposition of hydrogen peroxide will be investigated to see how the change in concentration of hydrogen peroxide and the change in temperature affect the rate of reaction. The data will be collected by measuring the gas pressure. The product of Hydrogen Peroxide is oxygen in a gas state thus it is mandatory to use

Four Elements of the Correction System Over the years the correction system has become a massive web of processing‚ treating and caring for more than 7 million people. Though not all of the 7 million people are housed in a jail or a prison‚ many are on probation or parole. And even though some of these are on probation and parole they are still considered part of the correction system. The four elements of the corrections system is probation‚ parole‚ jail‚ and prison. These four elements are in

Throughout this section I will be examining each of the essential reading elements and will evaluate the degree to which best practices are suggested in the CRP. As a reminder the essential reading elements are phonemic awareness‚ phonics‚ fluency‚ vocabulary‚ and comprehension. I will first start out with examining phonemic awareness and move on to each element. Phonemic awareness is the first essential reading element that is introduced and taught in this unit. The unit first begins with the practice
