Raghed Odeh Chemistry 227 11/08/2017 Which Alkali Metal Carbonate? Abstract In this experiment, the unknown metal carbonate was put in three different experiments to determine which substance the unknown carbonate had. Gravimetric analysis, simple weight loss and a flame test were done to help determine the unknown metal. The end results supported that the metal was Lithium with a 78.125 g/mol for the first method, a 60.08 g/mol for the second method and a red color for the third method. Introduction

Imagine seeing everything in blue? In November 2015 I was officially diagnosed with Meares-Irlen Syndrome. I was prescribed blue/turquoise tinted glasses and for everything to be printed on blue paper. This has had a large impact on my life as I struggle to read anything that is not in blue unless I want to strain my eyes, and obviously, everything is not going to be printed on blue paper. This has impacted my life for the worse as through confidence issues I find it difficult to ask people to

Procedure: (3 marks)* Summary of lab procedure – what YOUR GROUP did, include KEY observations – be concise! Someone should be able to repeat your experiment from this summary alone. (One partner should prepare the column while the other extracts the pigments out of the spinach leaves) - Preparing the Column: Add a small amount of cotton into the column covered with a thin layer of sand and clamp it. Dissolve silica gel in eluent and add it to the column while draining the eluent to make the stationary

periodically for 15 minutes. • (Do this in the fume hood) • Label a 50 ml vacuum flask and weight it to 4 places. • Support the labeled 50 ml vacuum flask using a ring stand and clamp. • Place a sintered funnel with a vacuum adaptor on the labeled flask. • Filter the solution by pouring the nutmeg/diethyl ether mix onto the sintered funnel. • Wash the Erlenmeyer flask with1-2 ml of diethyl ether and add it to the residue on the sintered funnel. Do this 3 times. • Evaporate the solvent using the airline in

Methods Preparing Spin Labels R5 spin labels were placed within a “kink-turn motif” site where the internal loop between nucleotides that are not base paired (Figure 2). This site was held constant throughout the study in both the 20-nucleotide RNA study and the 232-nucleotide mRNA study. Both the synthetic 20-nucleotide long mRNA and the R5 spin label precursor were purchased from lab companies; the mRNA was purchased from Dharmacon, and the R5 spin labels were purchased from Toronto Research Chemicals

Now we will be discussing the topic of what to feed your beardie. You will want to make sure that it gets a lot of protein by feeding it crickets or mealworms. Also, try to add in fruits and veggies such as romaine lettuce, sliced grapes, sliced carrots etc. If you're grossed out by the bugs you can get dry food mixtures in the store. You shouldn’t need to put a lot of water in the cage because they get a lot of their water from the insects they eat. Additionally beardies need a lot attention. If

Discussion: The aim of the experiment was to be using filtration techniques to help craft a makeshift water filter. The hypothesis for the experiment was that the dirty water containing dirt, rocks, trash and chemicals would all be separated by three fine screens, activated charcoal, sand, and tissue. This would keep out the unwanted materials and eventually filter into purified water. The makeshift filter was crafted with a soda bottle, funnel, fine screen, activated charcoal, sand, containers, paper towels

ABSTRACT Current Method of speech enhancement has been developed with adaptive filtering approach. The removal of unwanted signal i.e. noise from speech signals have applications ranging from cellular communications to front ends for speech recognition system. This paper describes proficient algorithm for removal of noise from speech. An optimal evaluation of LMS based adaptive filtering has been implemented for the observed noisy speech. This Algorithm is basic adaptive algorithm. This Adaptive
