identify the physical properties of each element physically govern to us. We carefully observed each test tube containing the element samples and was instructed to identify the symbols of each elements, the colors, the physical state that it was in and whether it was of a metallic or non-metallic nature. We then had to find the boiling point of methyl alcohol which was initially 65 degrees Celsius, in which we got a boiling point reading of 63 degrees Celsius. The next part of the experiment took us to finding out the solubility of solid in water, at this instance we created a mixture of copper sulfate crystal and water. We then gently shook the solution to try and create a homogenous or heterogeneous mixture. The copper sulfate crystal mixed perfectly which was discovered as a homogeneous solution and was soluble in the water as predicted. Another solid that was added to water to check if it was indeed insoluble or soluble was calcium carbonate. The calcium carbonate, during the solution preparation seems to be mixing

perfectly, but was showing separation a few minutes after the mixture was created which show that calcium carbonate was insoluble in water. The next leg of the experiment took us to trying to find out if amyl alcohol and methyl alcohol was soluble or I insoluble in water. In the test tube, amyl alcohol showed clear signs of separation once in was added to water and shaken, which was proven that it was insoluble in water. The methyl alcohol mixed evenly without evident differences in mixture which is proven to be soluble in water. The chemical state portion of the experiment instructed us to observe the reactions of elements, compounds, and solutions when heat and other compounds are added. To understand the reactions of element when heat is added, copper wire produced green flame within a few minutes of being heated, which then we observed the color of the wire changing to gray. We then observe the reactions of compounds, in which ammonium bicarbonate (NH4HCO3) was heated, the compound began to boil immediately once the head was added and disappears. We surprisingly saw little condensation on the top of the beaker and the smell of the ammonium remained as strong as before heat was added. The potassium bicarbonate (KhCo3) turned a brownish yellow once heated was added, but once the heat was removed, the compound showed no visible signs of change to it and remained in its original state. We then tried to
