3.2 Mechanochemical synthesis The mechanochemical method was employed to synthesis CP and MgCP where calcium hydroxide (CaOH2), phosphoric acid (H3PO4) and magnesium hydroxide (MgOH2) were used as precursors. Table 3.1 shows the parameter used by varying the weight percentages (wt. %) of Mg. Table 3.1: The weight percentages ratio for magnesium doped calcium phosphate Samples Parameter Calcium Hydroxide Ca(OH)2 (g) Phosphoric Acid H2PH03 (g) Magnesium Hydroxide Mg(OH)2 (g) Undoped CP 27…

The hypothesis that increasing the sucrose concentration from 6% (m/v) to 12 (m/v) would increase the rate of fermentation was not supported by the experiment. When looking at the graph it can be seen that the data obtained provided unclear results. Rather than the fermentation rate being significantly faster with a 12% (m/v) sucrose concentration throughout the entire study; the graph showed the fermentation rate for 12% (m/v) sucrose concentration was faster at times while the fermentation…

We all know that we have our own unique fingerprints but did you know that you can make sun prints? You may be wondering what a sunprint is, a sunprint is like a unique type of photo made with special sunprint paper that with the help of the sun creates a permanent image. A sunprint is formed when a chemical reaction happens with chemicals inside the paper,but before we talk about that, here is how you make a sunprint. You can make a sunprint by placing an object on a sheet of sunprint paper,…

The simple reaction between two substances (Mg and HCL) was performed to determine how different factors such as, temperature, and concentration effects the rate of reaction. There were noticeable differences while determining the effects of concentration of HCL on the rate of reaction. Increasing in the concentration of the HCL, bottom of the test tube became hotter; it’s an exothermic reaction because energy is being released during the reaction in the form of heat. Another, increasing in…

The protocol used to perform this experiment was followed as indicated by Simmons (2009). Three labeled glass jars with screw tops were obtained and approximately 8 grams of soda lime was added to only two of the jars. The other jar without soda lime served as a control to account for any CO2 already present in the chamber. All three jars were labeled with a number and location. Both jars containing the granules were oven dried to remove any water content for 24-hours. Next, jars were removed…

The purpose of the lab was to find which of the three balanced chemical equations was correct using decomposition & stoichiometry. After getting the necessary supplies for the lab, get the crucible and weigh it on the scale. After that, reset the scale so that it shows all zeros. Then put a certain amount (10,00 g), set up the ring stand and bunsen burner, so you can heat the crucible and baking soda effectively. The lab procedure and data supports the hypothesis, that if baking soda is heated,…

If heating magnesium in the presence of oxygen and they react completely, then the ionic compound’s empirical formula can be found using this equation by calculating the masses of magnesium and oxygen in this equation: Mg + O2 → MgxOy Since an ionic compound is the hopeful result of this lab, an ionic compound is a chemical compound comprising ions, which ions are an atom or molecule with a net electric charge due to the loss or gain of an electron. Ions can be negatively charged and called…

By measuring out two grams of our unknown, and heating it up until the difference of the mass of the test tube and the anhydrous residue subtracted to 0.002g, we were able to calculate the percent water in the two possible unknowns, and then our unknown, to figure out which unknown we were given. Since our percent water was 44.9%, we concluded that our unknown is Zinc Sulfate. A possible error as to why our calculated percent water was not exact to the theoretical percent water was most likely…

Comparing the masses, after and before reaction Aim To determine if mass is preserved in a chemical reaction conducted with vinegar and Sodium bicarbonate. Hypothesis: The mass of the flask and vinegar after the reaction will be less due to the fact that it is losing the gas which is being produced when the elements are mixed. However part B will be altered as the gas will be preserved inside the balloon. Apparatus  Balance  Sodium bicarbonate  Spatula  Measuring cylinder  2 conical…

There are several physical and chemical methods, of which the simplest method involves the reduction of the metal salt AgNO3 by NaBH4 in water. Wiley and his coworkers synthesized three different shapes of silver nanoparticles using chemical method, in which ethylene glycol used as both solvent and reducing agent [5]. This group synthesized cubic silver nanoparticles by reduction of silver nitrate (AgNO3) with ethylene glycol in the presence of Polyvinylpyrrolidone (PVP) and HCl. After synthesis…
