is matter? Anything that takes up space (volume) and has mass 2. Explain how to classify matter. (Homogeneous‚ Heterogeneous‚ Mixture‚ Pure Substance)? HOMOGENEOUS Matter that is made up of the same or alike particles Can’t see what makes it up Looks uniform HETEROGENEOUS Matter that is made up of different types of particles Can see what makes it up Mixture A material made up of two or more substances that can be easily separated Either Heterogeneous or Homogeneous Ex: Salsa‚ Cake

Distillation is the most commonly used separation process in the chemistry and petrochemical industry‚ mostly employed in

into a 250 mL Erlenmeyer flask‚ and then a thermometer was introduced to the cyclohexanol. A mixture of 4 mL of acetic acid and 115mL of commercial household bleach was slowly added to the flask‚ while swirling it. During adding the mixture‚ the temperature was kept between 40 degrees C-50 degrees C. The process took 15-20min. Once the 20 minutes was up‚ the mixture was tested by dropping some of the mixture onto a piece of starch iodide paper. After the test‚ the reaction was transferred to a 250mL

chloride tetrahydrate and 0.68 g of sodium acetate in 10 mL of distilled water. Add 1 g acetylacetone and swirl the mixture. With magnetic stirring‚ add dropwise a solution of 0.052 g potassium permanganate in 2.5 mL of distilled water over a period of 10-15 minutes. Stir for 10 minutes‚ then add dropwise a solution of 0.63 g sodium acetate in 2.5 mL distilled water. Heat the resulting mixture on a hot plate to between 60 and 70oC for 15 minutes‚ with stirring‚ then cool to room temperature. Isolate the

Abstract In order to experiment with distinct components of a mixture‚ they must be first separated so they can be observed individually. This is accomplished in this lab by the technique called thin layer chromatography (TLC). TLC involves a stationary phase‚ which the TLC plates as well as a mobile phase‚ which could be one of two solvents used: ethanol-acetone for TLC. Dyes in a sample separate consequently because of their unique polarities. As a result‚ nonpolar substances travel further

transparent liquids‚ the mixed salt and water can be easily separated again through boiling the mixture‚ making it a physical change because it is easily reversible. Vocab: 1. Homogeneous means similar in kind‚ composed of the same kinds. Furthermore‚ homogeneous mixture means that the components of a mixture are evenly distributed and cannot be easily told apart. For example‚ salad is a homogeneous mixture because we can easily tell the

Operations and Observations A mixture of ferrocene (1.5 g‚ 0.008 mol)‚ acetic anhydride (5 mL) and phosphoric acid (1 mL 85%) was heated over a steam bath until all the ferrocene dissolved and the mixture darkened from orange to dark red. The mixture was then refluxed with a calcium chloride drying tube for ten minutes and left to cool for an hour taking on a dark almost black colour. The reaction mixture was then poured onto ice (60 mL) and stirred to form brown mixture with some greenish black precipitate

Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient energy to escape from the surface to create a vapor pressure

The effects of gelatin on the process of Fermentation How does gelatin affect the process of fermentation? The experimenters hypothesized that the more gelatin that was added into the mixtures of yeast and water‚ the more the mixtures will ferment. The experimenter’s hypothesis was not determined correct or incorrect due to the inconclusive results of the experiment. Throughout the experiment‚ none of the balloons grew from fermentation. The results of the labs were meant to measure the CO₂ released
