Question

(5 Points) If you put a piece of zinc into a solution of copper (I) sulfate and allow the single replacement reaction to go to completion, how will you know which of the reactants is the limiting reactant? Write the balanced equation, including the states of matter of the reactants and products, to help support your answer.

CuSO4(___) + Zn (__) → Cu(__) + ZnSO4 (___)

Is it balanced? ____yes____ If not, fix it.

Answer 1

We need to balance the equation then can we say

`\\ \rm\Rrightarrow CuSO_4+Zn\longrightarrow Cu+ZnSO_4`

• It's already balanced

Zn does the reaction so zinc is the limiting reagent ,

Until zinc is present the reaction continues

Answer 2

Direct Redox Reactions. When a strip of zinc metal is placed into a blue solution of copper(II) sulfate ( Figure below ), a reaction immediately begins as the zinc strip begins to darken. If left in the solution for a longer period of time, the zinc will gradually decay due to oxidation to zinc ions
