In summary, the correct chemical equation for the reaction between Mg and Cu(NO3)2 is Mg + Cu(NO3)2 → Mg(NO3)2 + Cu. This is a single displacement reaction, also known as a single replacement reaction. The equation is determined to be correct by balancing the number of atoms on each side, with one magnesium atom and one copper atom on each side. The products of this reaction are magnesium nitrate and copper. This reaction is exothermic, releasing heat energy and causing a rise in temperature.

I was just wondering if this chemical equation is correct:

Mg + Cu(NO3)2 --> Cu + Mg(NO3)2

if magnesium is placed with the solution copper nitrate.

Thanks.

Yes. Magnesium is a more active metal, and it displaces copper.

1. What is the correct chemical equation for the reaction between Mg and Cu(NO3)2?

The correct chemical equation for this reaction is: Mg + Cu(NO3)2 → Mg(NO3)2 + Cu

2. What type of reaction is this?

This reaction is a single displacement reaction, also known as a single replacement reaction.

3. How do you know that this is the correct equation?

The correct equation for a chemical reaction is determined by balancing the number of atoms on each side of the equation. In this case, there is one magnesium atom on each side and one copper atom on each side, making it a balanced equation.
