However, the experiment only included one covalent bond, which decreased the reliability of the result because there could be some exceptional cases. Some strengths in the method were that they repeated each experiment for three times, which increased the reliability of the results. All the controlled variables are controlled correctly, which allowed a fair experiment. Some weaknesses in the method were that it only includes one substance for covalent bond, which can decrease the reliability as explained in the previous paragraphs. Another weakness would be that they used tap water as their solute. Tap water can contain other substances, therefore might affect the electrical conductivity. However, it probably did not have that much of an effect because they kept the solvent (tap water) controlled throughout the experiment. They did not use tap water for some trials and distilled water for other trials. Something I found difficult in carrying out the method was to make sure that the amount of substance is exactly 10g (or 30g or 60g). It is very hard to make sure the amount is to the exact amount

    The purpose of this lab was to be able to use physical characteristics to determine the identity of an unknown compound. The data from this experiment classified aluminum as metallic; ascorbic acid, paraffin, palmitic acid, sucrose, graphite, and water as molecular; sodium chloride as ionic. In order to determine this, 3 tests were conducted. The first test was to test the conductivity of each substance at room temperature. In this test, only graphite and aluminum conducted.

    In performing these sets of experiments, in which we would drop a water/water solution onto the surface of a penny, we were trying to test and experiment the bonding qualities of water when made into a solution compared to when the water is pure. When we dropped pure tap water on to a penny, the water, instead of flowing and spreading out, stayed together in a single drop on the penny. We wanted to see how different substances affected this phenomenon. When we formulated our guiding question we made sure to preserve these intents in the language: how do foreign substances influence the bonding quality and strength (to the top of a zinc penny in specific) of water? Since these experiments were conducted in groups, we set up a few roles to

    The quantitative solubility of the unknown compound was determined to be 29/100ml. The known solubility of sodium sulfate is 28.11g/100mL water. Using the found solubility to compare to the known solubility of sodium sulfate. This solution created in the solubility test, the conductivity of the unknown compound was tested using an Ohmmeter to measure the resistance of the solution. Resistance is the measure of a substances ability to conduct

    Goals The primary goal of this experiment was to identify an unknown compound by running various tests to determine the qualitative solubility, conductivity, and pH value of the compound. Tests were also performed for the presence of specific cations and anions in the compound. The second goal was to discover the reactivity of the unknown compound by reacting it with different types of substances. The third goal of this project was to calculate the quantitative solubility of the unknown compound in water.

    “Duckweed Recap” The duckweed lab was done to see the effects of road salt on the production of duckweed fronds. The purpose of this lab was to see if the salt concentration significantly affected the growth of the duckweed fronds. We had five different glass jar, one being a control with no salt in the water solution and four jars with different amounts of salt water concentrations and five ml of miracle grow in them. We started the experiment by putting four healthy and green duckweed plants with two fronds on each in every jar.

    Fahrenheit - Fahrenheit temperature scale Fahrenheit (symbol °F) is a temperature scale originally proposed in 1724 by the German physicist Daniel Gabriel Fahrenheit (1686–1736), after whom the scale is named. This original scale has been subjected to some revisions and adjustments reaching the current Fahrenheit temperature scale on which 32 °F is for the freezing point of water and 212 °F is for the boiling point (at sea level and standard atmospheric pressure). The normal body temperature has been considered in developing the scale that required an adjustment of normal human body to 98.6 °F. Fahrenheit temperature scale was common in English-speaking countries until the 1970s.

    Based on the R2 values from your graphs, do you think that density trends on the periodic table are linear relationships? What rationale could you offer to explain your answer? The R2 value established from the group 4 graph demonstrates a linear relationship with a steady increase. The period IV graph provided a very low value of R² = 0.0028 on the linear trendline and presents nearly any correlation at all.

    First source of error is observer subjectivity. The observations made on the qualitative results of the experiments are based entirely on observer’s ability to detect and interpret the results. A different observer may detect or interpret the same events differently. To avoid such errors, the observers should be briefed properly and in detail on the possible outcomes of the event so the record can have some uniformity between different observers, e.g., some guidance should be provided to determine what constitutes a small, medium and large piece of curd. Secondly, pH paper was used to determine the pH of the solution.
