    Introduction: During this unknown lab report various test were performed to differentiate microbes from each other and to compare metabolic and biochemical process. The gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan

    INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter

    sulphuric acid‚ nitric acid and ethanoic acid. What I already know Magnesium reacts with most dilute acids to give a magnesium salt and hydrogen. For example: Mg + 2HCl Mg + H2SO4 MgCl2 + H2 MgSO4 + H2 I discovered from an A’ level text book (A-level Chemistry by Ramsden) that nitric acid doesn’t usually give hydrogen‚ but may do with magnesium if the acid is cold and dilute. The book didn’t say how dilute the acid had to be. Other products may include oxides of nitrogen. I know that some acids are weak

    Lab Report 1  Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules
