Separating a Mixture, Recrystallization, pre-lab assignment could you also explain why you chose that substance for the empty spaces and question marks EXPERIMENT 4 Pre-Lab Assignment Separating a Mixture, Recrystalliration Name Date 1. Complete the following flowchart which shows how to separate a mixture of sand, sodium chloride and acetanilide. Notice that after a separation process (a down arrow) the filtered solids are shown on the left and the filtrate (the liquid) is shown on the right. The terminal step...
could this experiment have been done in a different order? for example, fe filing being removed at the end of the scheme. Why or Why not? Here is the procedure: INTRODUCTION Most of the matter around us con combination of two or more Mixtures have the following fundamental proper natter around us consists of mixtures of different substances. A mixture results from the tivo or more pure substances, elements or compounds that do not react chemically. • Each component of...
6. Describe a method for how you would identify the components of your mixture using GC. (3 pts)
How is it that cell fractionation can be used to separate nuclei, lipids, mitochondria, and ribosomes from one another? What properties of the components is/are being used for separation? What can you modify or change about the centrifugation process in order to separate mixtures of components whose properties are very similar?
Answer the question as indicated to earn all available points. A Chemistry student was given the following mixture: Small Styrofoam pellets, sand, salt, 1 cm diameter copper bbs, and iron filings. He/she has access to the following materials and equipment: beakers, magnets, sieves with 5-mm holes, hot plates, watch glasses, tweezers, coffee filters, and small fish nets. Describe how he/she would separate each component from the mixture, what material/equipment he/she would employ, and which property (ies) of matter he/she would...
Describe the 4 components of fitness. Explain how carbohydrates, fats and proteins are used for energy during physical activity. What changes could you / would you do to increase your physicial activity? COURSE: Essentials of Nutrition
Given a mixture of KI, benzoic acid, naphthalene, and 1-adamantanamine, how would you separate them into individual components using liquid-liquid extraction? Use a flow chart to explain the process.
17.70 Describe how you could separate the following mixture of metal ions: Na+, Hg2+, and Ca2+.
4. The compounds in a mixture separated by GC can be identified by their retention times. If you Suructor nad not told you which peak in the GC chromatogram corresponded to which alker you didn't know the boiling points of the alkenes, how could you determine the identity or each peak by its retention time? Identities of the components in a mixture separated by GC can also be determined by the technique called "spiking". Suppose you had run a chromatogram...
