NH3 and CuSO4 Experiment Results Almost every solution made had some type of chemical reactivity. Most solutions changed colors revealing the acidity or alkalinity of a chemical and some exposing the presence of starch. The exception in the change of appearance was the chemicals HCI and phenolphthalein which was in the

LAB 1 – THE SCIENTIFIC METHOD *Adapted from LabPaq CK-GCC Purpose: The purpose of this experiment is to learn about and use the Scientific Method. The discussion of physical properties such as density‚ color‚ texture‚ smell‚ and solubility will take place. Observations and Experimental Data: Table 1: Making Observations Procedure Observation A. Torn paper Vertical tear: easier to tear‚ more visible fibers‚ more jagged edges and uneven tear. Horizontal tear: harder to tear‚

always want to be the best in everything especially kids. By not having competition in school kids would not care about doing good and being successful. Either way you cant really stop competition in schools because it will always be there. Seperation of state and church: I think that state and church should be seperated because not everyone in the a state believes in the same religion or goes to the same church‚ so we shouldnt base laws of something that not everyone believes in.

and products of the reaction‚ to determine the actual yield vs. the theoretical yield and to calculate the percent yield. A Precipitation reaction begins by combining two aqueous solutions to form a precipitate‚ an insoluble product that is also a solid. With my knowledge of the measuring scale‚ I was able to use the scale with no problem throughout the whole experiment. The mass of the weighing dish was 0.5 grams. Initially it was calculated that 0.68 g of CaCO3 was needed for a full reaction

Furthermore‚ later on the poem‚ with the allusions to death and related death imagery‚ the persona suggests that time‚ and the death which only time can bring‚ will signal the final act of seperation between the persona and his subject.

For starters‚ unity was difficult in india because of its geography that created sort of a seperation. however‚ the geography made it more open to outer influences like the Aryans. rome was more or less unified geographically‚ as it had many rolling hills instead of mountain ranges in parts of india.

How does the british government system still effect Austalia’s government system today? In 1770 James Cook‚ a british Captain‚ claimed the east coast of Australia for the British Crown‚ under strict instruction from King George III. The British colonisation started eighteen years later‚ with the arrival of the first fleet. This fleet established a british penal colony‚ a place wher the british government sendt criminals. The penal colony is the one that later on became Sydne. This were to be the

alcohol is also measured after 2nd process as 82%. INTRODUCTION The objective of this experiment is to distillate the alcohol-water solution into ethanol and water. Distillation is a process of separating mixtures based on differences in volatilities of components in a boiling liquid mixture. Distillation is a unit operation‚ or a physical separation process‚ and not a chemical reaction. The basic requirement of distillation is that the components of the liquid solution must have different boiling
