Question

Magnesium + Cadmium (II) Nitrate____________________________steps are in the picture provided

Answer 1

Answer:

$Mg\placeholder{⬚}_{(s)\text{ }}\text{ + Cd\lparen NO}_3)\placeholder{⬚}_{2(aq)}\text{ }\rightarrow\text{ Mg\lparen NO}_3)\placeholder{⬚}_{2(aq)}\text{ + Cd}_{(s)}$

It is a single replacement (SR) reaction also known as displacement reaction

Explanation:

Here, we want to write the equation of reaction for the single replacement of magnesium and cadmium (II) nitrate

Magnesium ion is higher up than cadmium (ii) ion in the electrochemical series. What this means is that it can displace it from its salt

We have the equation of reaction in words as:

$Magnesium\text{ + Cadmium\lparen II\rparen Nitrate }\rightarrow\text{ Magnesium Nitrate + Cadmium}$

Using their symbols, we have the equation above as:

$Mg\placeholder{⬚}_{(s)}\text{ + Cd\lparen NO}_3)\placeholder{⬚}_{(aq)}\text{ + Mg\lparen NO}_3)\placeholder{⬚}_{2(aq)}\text{ + Cd}_{(s)}$
