How this reaction (during qualitative analysis) is possible: $Zn^(2+)$ + NaOH ------> $Zn(OH)2$ + $Na^(2+)$ if Zinc is below Sodium in the reactivity series?

you are confused. Na is the more reactive, while Na+ (and not Na2+, that doesn't exist) is a spectator ion. Zn2+ is an amphoteric ion. The doer with zinc is the hydroxyl ion

How do I determine the mass of zinc iodide from the filtration of a zinc iodide solution?

Because zinc iodide is soluble in water, you need to let the water evaporate until the zinc iodide is completely dry. You can do this more quickly in a drying...

How do I calculate the mass of zinc and iodine that are consumed to produce zinc iodide?

In a chemical reaction, the mass of a substance that is consumed refers to one or more reactants. In the case of your question, the reactants are zinc and iodine,...

Zinc phosphide, $Zn_3P_2$, is often used as a rat poison. Phosphorus has 5 valence electrons. How many valence electrons does each zinc atom lose?

And the zinc cation is $Zn^(2+)$. When the ions form a salt, clearly they form an electrically neutral species; and thus the formulation of the salt is $Zn_3P_2$. Each phosphorus...

How do you write an equation to represent "zinc reacts with copper (II) nitrate to form zinc nitrate and copper"?

Zinc is a more active metal than copper (it lies higher up the activity series). Therefore zinc metal will displace copper from aqueous solution, resulting in deposition of a copper...

What determines if in a reaction between sodium chloride and sulfuric acid you will get sodium bisulfate or sodium sulfate?

If 2 equiv sodium hydroxide are used: $H_2SO_4(aq) + 2NaOH(aq) rarr Na_2SO_4(aq) + 2H_2O(l)$ If 1 equiv sodium hydroxide is used: $H_2SO_4(aq) + NaOH(aq) rarr NaHSO_4(aq) + H_2O(l)$ Both reactions...

I measured $"5.00 g"$ copper sulfate solid and $"6.530 g"$ zinc. If for this reaction $q_(rxn) = "979.72 cal"$ of energy was involved, why is my percent error of the standard enthalpy of reaction for the reaction of zinc with copper sulfate so big???

Based on the information I got from you: $m_"Zn" = "6.530 g"$ $m_("CuSO"_4cdot5"H"_2"O") = "5.00 g"$ (in lab you tend to be handed the hydrate) From the molar...
