Chemistry Lab Report (Redox Reactions) Questions: • What will happen when you put zinc in copper II sulfate? • What will happen when you put copper in copper II sulfate? Predictions: • We can predict that zinc will react with the aqueous solution of copper II sulfate and we will notice a reaction. We can also predict that the copper will not react with the solution of copper II sulfate and no reaction will be noticed. Hypothesis: • It is hypothesized the zinc metal will have a precipitation reaction

Iron-Copper co doped bismuth vanadate‚ has led to the formation of the BIFECUVOX solid solution in the composition range 0.05≤x≤0.20 were synthesized by standard solid state reactions. Fe and Cu substitution effects on the phase stabilityand electrical performance in the parent bismuth vanadate and was investigated by combining results obtained fromPowder X-ray diffraction (PXRD)‚ Differential Thermal analysis (DTA)‚ Thermogravimetric analysis (TGA)‚Scanning Electron Microscopy(SEM) and AC impedance

Measurement of the distance‚ the thickness and the radius of curvature Purpose : To learn how to use vernier caliper‚ micrometer and spherometer to measure internal and external diameters of a pipe‚the thickness of a copper rods‚ and the radius of curvature of spherical lenses. 1) Vernier caliper: As shown in Fig. 1 the main fixed scale in the vernier caliper has 1 mm gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each
Premium Heart rate
The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an aqueous state or a solid state as a
