Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they

Alum Lab Conclusion The purpose of this laboratory was to use two different techniques to attempt to identify the melting point and the mole ratio of hydrated water to anhydrous aluminum‚ potassium‚ and sulfate of AlKSO4. The hypotheses were: if the alum was put in a capillary tube the melting point of alum will be able to be determined; and the water of hydration in alum crystals will be possible to determine if the alum is heated with a Bunsen burner.

VI- CONCLUSION The eye is the organ of vision. It has a complex structure consisting of a transparent lens that focuses light on the retina. The retina is covered with two basic types of light-sensitive cells-rods and cones. The cone cells are sensitive to color and are located in the part of the retina called the fovea‚ where the light is focused by the lens. The rod cells are not sensitive to color‚ but have greater sensitivity to light than the cone cells. These cells are located around the
