PART A: If a test tube is placed over a flame, the gas that is collected creates a combustion reaction. What is the balanced equation for the reaction? PART B: The vinegar and baking soda react to generate carbon dioxide gas. The gas is then bubbled into the limewater. The first gas to come out of the tube will be mostly air until the large test tube fills up with the carbon dioxide gas. a. Write a balanced equation for...

Candles contain paraffin wax, a hydrocarbon. When a test tube filled with cold water is placed over a burning candle, condensation appears on the outside of the test tube. If a large Kari’s inverted over the burning candle, and the gas in the jar is bubbled via suction through a solution containing calcium hydroxide, CA(OH)2, a white precipitate of CaCO3 is observed. Explain these observations based on the products of combustion.

The following combination of solutions will be added to a medium test tube and observations will be recorded. For each precipitation provide the NET IONIC EQUATION and the FORMULA UNIT EQUATION. If no reaction occurs, write NR (No Reaction). Obtain three medium test tubes and add roughly 5 mL of 0.100 M Cu(NO3). Use (i) as your guide. The exact volume is not important. Then add dropwise each of the following: 1) 0.100 M Na co Write the NIE and...
