Complete and balance the equation. Zinc + Hydrochloric Acid → ………………....... + …………………….. ……… + ……………………… → …………………… + ………………………. • Classify the reaction : • Combination reaction; • Decomposition reaction ; • Precipitation reaction; • Combustion reaction; • Neutralisation reaction; or a • Displacement reaction What gas was formed? ………………………………………………………………..
Experiment – Part B Drop a small piece of iron into a test tube containing 1-2 ml of 1.0 M copper (II) sulfate solution. Results REACTANTS PRODUCTS iron + copper (II) sulfate→ ………………………… + …………………………….
TASKS 1. Complete and balance the equation. ……………………… + ……………………. → ………………………. + …………………….. 2. Classify the reaction.3. The blue color in the copper sulfate solution is due to the presence of what ion?4. Predict the color of a copper nitrate solution.
