The Reaction Between Iodine & Zinc with Water Added: In the hood finely powdered zinc will be added to iodine under standard conditions. The two solids will be mixed using a spatula. A small amount of water is then squirted into the evaporating dish holding the mixture.
a) Provide a balanced chemical reaction describing the behavior for the reaction including parenthetical information indicating the physical nature of the reactants and products.
b) What is the role of the water that was squirted into the reaction? Would you include water in the balanced chemical reaction?
c) How does the reactivity of the Zn/I2reaction compare to that of the Al/Br2 and Sb/Br2 reactions?
c) Are there any particular hazards associated with the use of zinc dust and iodine? Any special precautions taken when running the reaction.
d) From these three reactions (Zn/I2, Al/Br2 and Sb/Br2 reactions), which metal do you think is the most reactive, Al, Sb, or Zn?

I really just need all the equations, please and thank you.
MATERIALS: cene nitric acid, HNO, 3.0M sodium hydroxide, NaOH 6.0 M sulfuric acid, H2SO4 zine metal DI water PROCEDURE: Make sure you record detailed observations after almost every step. You will also need to write the balanced chemical equations for almost every step. Make sure you answer any questions associated with a step 1. Weigh approximately 0.5 g of copper metal and record the weight. Place the copper in...

4. In parts I and II of this experiment, were the same atoms oxidized? Explain. 83 When this reaction occurs, the Zn atom loses two electrons. Two fodine atoms pick up one electron cach from the Zn. In the second part of the experiment the Znly that you formed will undergo electrolysis using a battery to decompose into elemental zinc cathode. These electrons are picked up by Zn2+ sons producing metallic Zn, which accumulates on the copper cathode. Zn2+ +...

Organic chemistry post-lab question: "Why is important
to add the alkyl halide dropwise in your reaction? (Hint: your
reaction is not heated, but you still need a water-cooled
condenser!)" Please answer in detail!

can anyone please help me with this? i have no clue how to define
if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
