1. Using chemical formulas, write out the equations of the three reactions you will do, then balance. 2. Classify the reactions as synthesis, decomposition, single displacement or double displacement. Note: the first reaction is a redox reaction and does not fall into any one of the other four categories. (1) Redox. (2) (3) 3. During reaction 1, a brown gas is produced. What is its formula? 7. Reaction 2 involves combining a solution of sodium hydroxide with a solution of copper (II) nitrate. The sodium hydroxide solution is colorless. a. What color is the copper (II) nitrate solution? b. What species is responsible for this color? How do you know when reaction 3 is complete? A student started with 0.3295 g of copper. The mass of filter paper and copper (II) oxide product was found to be 0.5723 g, and that of the filter paper alone was 0.2568 g. Calculate the percent yield of copper (II) oxide.
