PURPOSE The purpose of this experiment is to become familiar with the separation of mixtures of solid and learn separation techniques based on the chemical properties of a substance. PROCEDURES 1. Separating out the Iron a. Use your digital scale to determine the mass of your weighing dish. b. Empty the entire mixture of solids from the plastic bag into the weighing dish and determine the gross mass of the total mixture and weighing dish. Compute the net mass of the mixture: this is equal

When a solute is dissolved in a liquid‚ the temperature at which that liquid freezes decreases‚ because the molecules of the solute become attached to the water molecules‚ making it more difficult for the water to form its crystaline shape and form into ice. This process is called Freezing

Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized salt

V. HAZADOUS WASTE TREATMENT PROCESS Presently‚ the hazardous waste treatment technologies are highly developed from the decade before due to the more environmental and ecosystem concerning. Moreover‚ hazardous waste not threaten only environment but also to human hygiene and health. However‚ one of the most dangerous hazardous waste is dichlorodiphenyltrichloroethane (DDT). Addition‚ DDT is used as a majority pesticide during agriculture revolution period‚ and also uses to regulate Malaria in developing

Flowers vary in size from 1 inch to 2 inches in diameter. It is a perennial aquatic plant whose long stems creeping over mud or shallow water. It came from South America to the U.K. It is introduces as ornamental and water garden plant. It is first recorded in 1999. The creeping water primroses can cause a lot

So far‚ I have learned many new things about the effects of both ADHD and Ritalin on the human body as well as different forms of behavioral therapy. I have learned that ADHD affects the areas of the brain that control attention and self-control and that as a stimulant‚ Ritalin stimulates these areas of the brain to enhance them. I have also learned that there are three different types of the disorder‚ which are inattentive ADHD‚ hyperactive-impulsive ADHD‚ and combined ADHD. I have also learned
