Balance Fe(s) + Ca(NO3)2(aq)->

Chemistry
1 answer:
Bess [88]3 years ago

Fe(s)+Ca(NO₃)₂(aq)⇒no reaction

<h3>Further explanation</h3>

In voltaic series  

Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au  

The more to the left, the metal is more reactive (easily release electrons) and the stronger reducing agent  

The more to the right, the metal is less reactive (harder to release electrons) and the stronger oxidizing agent  

So that the element located on the left can push the element on the right in the redox reaction  

Reaction

Fe(s)+Ca(NO₃)₂(aq)⇒no reaction

Fe cannot reduce Ca because Ca is more reactive, so the reaction does not occur

On the contrary, this reaction can occur

3Ca(s) + 2Fe(NO₃)₃(aq) = 3Ca(NO₃)₂(aq) + 2Fe(s)

Which mechanisms is most significant in returning the ion concentrations to the resting state?
IceJOKER [234]

Answer:

Active transport by the Na+-K+ pump

Explanation:

Active transport by the Na+-K+ pump

Maintenance (and restoration) of the resting ion concentrations depends on the Na+-K+ pump. Once gated ion channels are closed, the combined action of the pump and ion leakage (particularly that of K+) establishes a resting membrane potential in a typical neuron of around âˆ'70 mV.
