Unless you use it once a month or less‚ don’t use a nail polish remover with acetone in it. Though acetone will make removing the nail polish easier‚ it can damage the nails themselves. * If you have and wish to keep fake nails‚ such as acrylic‚ choose a polish that will not remove them‚ and don’t let it soak much. 3.

CHAPTER I INTRODUCTION Pollution is one of the main problems the world faces today. One of the reasons is the overload of non-biodegradable objects like plastics‚ cans and Styrofoam. The invention of plastics and Styrofoam made a huge change in our society and it helped us in many ways. But it is also one of the main pollutants that destroy our planet. Because of these we devised a way to recycle used Styrofoam‚ and this is to make glue out of it. This glue can help reduce the number of Styrofoam

This means that the male smoking rate is

And my final copper sample may have picked up impurities along the way‚ which made it darker in colour. 8. Acetone is a flammable ketone.

Under the fume hood‚ the chromatography solvent (90% petroleum ether: 10% acetone) will be added to the tube‚ approximately 2 ml is enough. The paper is then placed in the solvent‚ while making sure the sample line is above the solvent and dry. You will then cover the top of the tube with Parafilm and set it aside. At about 30

November 15‚ 2007 Synthesis of 1-Bromobutane Introduction: The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved in water and sulfuric acid will be added. The addition of sulfuric acid will

by : Directorate of Education‚ Delhi SOME IMPORTANT REASONING BASED QUESTIONS OF ORGANIC CHEMISTRY 1. Chlorobenzene is less reactive than chloromethane. Ans. In chlorobenzene‚ each carbon atom of benzenering is sp2 hyridised and is electron withdrawing. Chlorine atom donates a lone pair of electron and acquire positive charge. The negative charge is delocalised on ortho and para position by resonance. C-Cl bond acquires partial double bond character and is 169 pm as compared to 17.0 pm in chloromethane
