write a balanced chemical equation for each single replacement reaction that takes place in aqueous solution. write no reaction
Illusion [34]

The question is incomplete, here is the complete question:

Write a balanced chemical equation for each single replacement reaction that takes place in aqueous solution. write no reaction if a reaction does not occur

1.) Zn + PbCl₂

2.) Cu + Fe(NO₃)₂

<u>Answer:</u>

<u>For 1:</u> The reaction does occur.

<u>For 2:</u> The reaction does not occur.

<u>Explanation:</u>

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

A+BC\rightarrow AC+B

For the given options:

  • <u>For 1:</u>

Zinc is more reactive than lead as it lies above in the series. So, it will displace lead from its chemical equation.

The chemical equation for the reaction of zinc and lead chloride follows:

Zn+PbCl_2\rightarrow ZnCl_2+Pb

  • <u>For 2:</u>

Copper is less reactive than iron as it lies below in the series. So, it will not displace iron from its chemical equation.

The chemical equation for the reaction of copper and iron (II) nitrate follows:

Cu+Fe(NO_3)_2\rightarrow \text{No reaction}

How can you differentiate the Atomic Structure and the Bohr Model? In other words, how is the Atomic Structure different from th
Tatiana [17]

Answer:

Bohr thought that electrons orbited the nucleus in circular paths; whereas in the modern view atomic electron structure is more like 3D standing waves. Bohr built upon Rutherford's model of the atom. ... He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies.
