Title: Factors affecting reaction ratesProcedure A: Effect of ConcentrationAim: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant‚ the faster the rate of reaction. Materials: 2M hydrochloric acid solution‚ magnesium wire‚ distilled water‚ 4 test-tubes‚ measuringcylinder. Procedure:1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder. 2)A 3cm length of magnesium wire is added to

Design Lab #17: Reaction Rate - Calcium Carbonate & Hydrochloric acid Design D: Introduction: In this experiment calcium carbonate will be put into a flask and mixed with hydrochloric acid to produce calcium chloride‚ water and carbon dioxide. The formula for this reaction is: CaCO3(s) + 2HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l) Purpose: The purpose of this experiment is to determine how the surface area of CaCO3(s) affects the rate of

What is a Medical laboratory technician? A laboratory technician process specimens and perform laboratory tests ordered by physicians and medical technologists. Many specialize in cytotechnology‚ hematology or microbiology. As a medical technician‚ you may perform tests on saliva‚ blood‚ and tissue samples and then be responsible for recording and sharing the results with the physician. Performing these tests often requires the ability to operating various medical machines and equipment. You may

Laboratory Safety Standards Jill Olson A school science laboratory is an excellent setting for students to explore and investigate the world around them. Almost every part of students’ lives is affected by science. Allowing them to see‚ touch‚ and manipulate objects in a laboratory situation gives students the real world experience to get them excited about science and to prepare them for college and beyond. However‚ James A. Kaufman‚ director of the Laboratory Safety Institute‚ proposes that

OBJECTIVE To determine antiseptics evaluation by the filter paper disc method INTRODUCTION An antiseptic is a substance which inhibits the growth and development of microorganisms. Antiseptics are a diverse class of drugs which are applied to skin surfaces or mucous membranes for their anti-infective effects. This may be either bacteriocidal or bacteriostatic. Their uses include cleansing of skin and wound surfaces after injury‚ preparation of skin surfaces prior to injections or surgical procedures

Measurement and Uncertainty When recording data‚ each entry should be given a corresponding estimated error‚ or uncertainty. The uncertainty gives the reader an idea of the precision and accuracy of your measurements. Use the following method for finding the uncertainty associated with any measuring device used in lab. First‚ find the least count‚ or the smallest printed increment‚ of the measuring device. On the meter sticks‚ the least count is 1 mm. On the double pan balances‚ the least count
