Chemical Reaction Lab Report Student

In this experiment, the student was presented with five of the most common types of chemical reactions and practiced balancing chemical equations. Additionally, the student went through an extensive list of chemical reactions was asked to classify the chemical reactions and balance them. In particular, the student was asked to do this for the reactions of: mixing 3 mL calcium chloride with 2 mL sodium phosphate, adding a few drops of water to a test tube containing 0.5 g copper sulfate, heating 0.5 g of copper(II) hydroxide in a test tube, adding a square piece of zinc to a test tube containing 3 mL 3M hydrochloric acid, mixing 2 mL 3M hydrochloric acid with 2 mL sodium carbonate, adding 0.1 g MnO2 to a test tube with 3 mL hydrogen peroxide, combusting a sodium acetate and ethanol solution, mixing 3 g ammonium chloride and 7 g strontium hydroxide octahydrate together and swirling the solution, mixing 2 mL sulfuric acid and 4 mL sodium hydroxide together,

Evidence of this is shown in the case where the students dump samples into the organic waste container to clean out their glassware, which lead to reactions such as smoke appearing and sizzling, as one student noted. Additionally, there is the case in which glassware may not be cleaned properly, which may lead to the forming of a potentially dangerous reaction. It may also matter which reactants are added to which, though this is more than likely not a possibility, at least not in this experiment. Moreover, students may get no reaction for reactions that actually happen, and this is due to the fact that the reaction may take awhile to occur. Finally, there may even be the case that the student mistakenly combines two substances that aren’t supposed to be combined, due to carelessness or
