what is produced during the replacement reaction of cu(no3)2 and zn?\no znno3 + cu\no zn + cu(no3)2\no zncu + 2no3\no zn(no3)2 + cu
Answer
Explanation:
Step1: Recall single - replacement reaction rule
In a single - replacement reaction of the form $A + BC\rightarrow AC + B$, where $A$ is more reactive than $B$. Zinc ($Zn$) is more reactive than copper ($Cu$) according to the metal activity series.
Step2: Write the reaction equation
The reaction between $Zn$ and $Cu(NO_3)_2$ is $Zn+Cu(NO_3)_2\rightarrow Zn(NO_3)_2 + Cu$. Zinc replaces copper in copper(II) nitrate to form zinc nitrate and copper.
Answer:
$Zn(NO_3)_2 + Cu$ (the fourth option)
