proceed with caution at all times in the laboratory. Take care not to bump another student‚ and remain in your laboratory station while performing an experiment. An unattended experiment can produce an accident. 4. Proper safety apparels‚ such as goggles and everyone should wear gloves when performing experiments that require precaution. 5. Your apparel should be appropriate for laboratory work. Long hanging necklaces‚ bulky jewelry‚ and excessive and bulky clothing should not be worn in the laboratory

Get all the equipment’s ready and put them on a table. Take a pair of goggles and put them on and make sure hair is tied up‚ if long‚ using any sort of hair band. Take the 100ml glass beaker and place it under the water tap’s opening‚ the place where the water comes out from‚ then turn the tap on. Do not turn the tap off until the water inside the beaker reaches the 50ml mark‚ to ensure that there is only 50ml of water in the 100ml beaker. Then take the beaker and place it somewhere safe on the table

The Separation of Mixtures This lab demonstrates the difficult task of separating mixtures using different types of methods. This study is performed because it helps you understand the concept of separation and certain characteristics of elements. Previous knowledge in which already exists in this lab would be the process of filtration‚ distillation‚ magnetism‚ and evaporation. The specific hypotheses of this experiment was that the iron would separate through magnetism‚ the salt would separate

1. Ventilate the work area well‚ cover the work space with newspaper‚ and put on gloves and goggles. Be sure pets and kids are not running underfoot as begin this project. 2. Start by measuring the oils and placing them into the crock pot. Remember: For this recipe measuring all ingredients by weight‚ not by volume. 3. Turn the crock pot on high and melt all the oils. Better to use a smaller crock pot to cook the ingredients down and then move to a larger one once start adding the liquids. 4. Place

Hence this experiment is mainly goes around with how to determine the empirical formula of Magnesium Oxide following various tight procedures in order to get the knowledge and apply it onto another compounds. We are investigating the empirical formula of Magnesium Oxide in this

Honors Chemistry p: 5 27 September 2013 Chemical Applications in Real Life Scenarios “Case Study B” Although chemicals generally have the same appearance in a liquid solution‚ they vary extremely from the fact that some may have no effect and others can cause death. One of the few ways that a certain chemical solution can be identified is through a simple test called a flame test. A flame test works by placing a certain chemical solution in an open flame and noting the color the flame changes
