different temperatures 1 .Distillation is only effective if there is a significant difference between the boiling of the two elements. Every element had a unique boiling point specific to the amount of bondsand structure of that element.With that said‚ in this distillation lab the solution used was 50/50 ethanol-water.The normal boiling point of ethanol is 78°C while the normal boiling point of water is100 °C. Theoretically‚ as the solution heated in a distillation apparatus‚ the temperature begins

purifying liquids based upon their boiling points and their differences in vapour pressure. Distillation is a process in which one liquid is separated from another liquid‚ or a liquid from a non-volatile solid. During the distillation process‚ the component with the lower boiling point will vapourize first and thereby will travel through the condenser to liquefy in the collection flask before the component of higher boiling point. This process works best when the boiling points of the components are significantly

MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting point. Boiling point

about how foods react to and inter-act with each other in a culinary or scientific manner‚ all I know is I really like to dip things in chocolate. My problem I had was that my chocolates kept burning‚ even though I was using the same method (double boiling) to melt each type of chocolate. I couldn’t understand why each of them reacted differently to the same method of heating (physical stimuli). I was thinking how cooking is like a science experiment in some ways. For example‚ you come up with an

Ontario regulation 455/07 and the demerit point system The Ontario regulation 455/07 and the demerit system work together in order to promote safe driving on roads and to discourage dangerous activities on roads. Regulation 455/07 is a very detailed article containing rules against extreme drivers. It contains rules prohibiting stunts and racing on roads. Withing the article‚ stunts are defined as drivers attempting to lift one or all of the vehicle’s wheels off of the road‚ to lose traction

experiment was to investigate the effects of salt type and concentrations on the rate of heating and the boiling point. Then from this data make a conclusion which salt type and concentration is the most energy efficient at heating water to its boiling point. It was hypothesised that highest concentration of MgCl2 was going to be the most energy efficient at heating the solution to its boiling point. This is because MgCl2 has the lowest specific heat capacity thus will use the least amount of energy

PointsAshley Mita History 2020 Wilson’s Last Seven Points The Fourteen Points were listed in a speech delivered by President Woodrow Wilson of the United States to the United States Congress on January 8‚ 1918. This speech was intended to reassure the country that the war was being fought for a good cause and for peace in Europe after World War I. However‚ that was not necessarily correct‚ and later on caused more issues. The eighth point Wilson discussed was that France was invaded by Germany
