EXPERIMENT 7 - Distillation – Separation of a Mixture Purpose: a) To purify a compound by separating it from a non-volatile or less-volatile material. b) To separate a mixture of two miscible liquids (liquids that mix in all proportions) with different boiling points. Equipment / Materials: large test tubes(3) clamp (1 or 2) ringstand boiling chips test tube rack (1) heating mantle glass adaptor thermometer adaptor 10-mL graduated cylinder condenser (1 or 2) grease 50- mL round bottom flask 50-

remains constant. A pure substance melts at a precisely defined temperature‚ characteristic of every crystalline substance and dependent only on pressure (though the pressure dependency is generally considered insignificant). Determining the MP is a simple and fast method used in many diverse areas of chemistry to obtain a first impression of the purity of a substance. This is because even small quantities of impurities change the melting point‚ or at least clearly enlarge its melting range. The boiling

M1: discuss the characteristics and causes of one type of challenging behaviour Aggression is a difficult behaviour to predict but also it is often hard to control. It comes in many physical‚ verbal and non-verbal forms. Physical aggression can appear from as little as slapping/ hitting a person to firing a gun at someone. Verbal aggression can be someone screaming or using abusive/racist language and non-verbal can include things like using offensive gestures or invading an individual’s personal

Goals The purpose of the lab experiment is to explore simple harmonic motion (SHM). We will accomplish this through the validation of harmonic calculations and ultimately creating a time piece (oscillator) Method In part A (Simple Pendulum) we will measure the effects of mass on the period of the pendulum. We will also calculate the period using small angular displacements and compare the results. We will also explore the effects on the period when the angular displacement is not “very small”

When you become a young adult‚ life is never as simple as it used to be. Back in your single-digit ages‚ you have feelings of elation and excitement when holding a crisp ten-dollar bill in your hand. Today‚ it is replaced by discomfort and uneasiness when you find out it’s the only bill you have in your empty wallet. The feeling of enlightenment when learning something new is replaced by irritation when you ask yourself why you didn’t learn it sooner. A mission most children wish to pursue is the
