Classifying Chemical Reactions
Introduction
Pre-lab questions
1. Which reactants used in this experiment are flammable? Discuss the safety precautions that are necessary when working with flammable materials in the lab?
2. Summarize the following description of a chemical reaction in the form of a balanced chemical equation?
3. Common observations of a chemical reaction are described in the introduction section. For each observation, name a common or everyday occurrence that must involve a chemical reaction?
Research question
What is the appearance of reactant, Evidence of chemical reaction, and properties of a product?
Background information
The experiment is to observe a variety of chemical reactions and to identify patterns in the observation of reactants into products. The properties of the reactions will be analyzed to classify the chemical reactions into different groups.
Hypothesis
Reaction 1- My hypothesis for reaction 1 is that the magnesium ribbon will crumble. The explanation i have for this is that i when you put a object long enough on a fire it will probably crumble.
Reaction 2- My hypothesis for reaction 2 is that the magnesium metal ribbon will make. The test tube will become hot. When a burning wood split is placed in the mouth of the tube, the flame goes out and the remains go in the tube.
Reaction 3- My hypothesis for reaction 3 is that the moistened litmus paper changes color. The odor will be a chemical odor that smells bad. The burning splint will be extinguished.
Reaction 4- My hypothesis for reaction 4 is that adding hydrochloric acid to solid calcium carbonate produces bubbles maybe. When burning the splint is placed on the test tube, the flame is extinguished.
Reaction 5- My hypothesis for reaction 5 is that mozzy zinc in the test tube will make smoke come out of the tube
Reaction 6 - My hypothesis for reaction 6 is that when you add the 0.5 M of copper (11) chloride and mix it with the 0.5 M of sodium phosphate they will
