All of the ionic compounds were both electrolytes and soluble‚ demonstrating that that part of our conclusion was correct. However‚ two ionic compounds were shown to be acids (Copper(II) Sulfate and Potassium Carbonate). All but one of the molecular compounds were soluble‚ the exception being Paraffin Wax. However‚ we were wrong in our hypothesis that no molecular compounds were electrolytes‚ as the two acids (Sulfuric acid and Hydrochloric acid) were electrolytes

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

original state and the percent of the hydrate recovered was calculated by using the mass of the rehydrated sample by the mass of the original hydrate and then multiplied by 100%. Data Presentation & Analysis Table 1: The data was collected from the lab experiment. Sample calculations are shown. Mass of beaker with sample 30.765g Mass of empty beaker 30.263g Mass of sample .502g Mass of beaker with sample after 1st heat 30.661g Mass of beaker with sample after 2nd heat 30.657g Heating mass

the onion‚ the red-spot nucleus can be seen clearly when it is stained with aceto-orcein solution. The last experiment is to test the existence of proteins in cooked egg white. If protein is present in cooked egg white‚ the transparent solution of sodium hydroxide and cooked egg white will turn into purple when it is mixed with copper sulfate solution. Therefore‚ all macromolecules exist in all given samples. Introduction Macromolecules are large organic molecules which can be categorized into four

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from
