Solid magnesium reacts with aqueous copper (I) nitrate to from aqueous magnesium nitrate and solid copper express as a chemical equation

Balanced chemical equation:

Mg(s) + 2CuNO₃(aq)    →    Mg(NO₃)₂ (aq)  + 2Cu (s)

Explanation:

Word equation:

Magnesium + copper(I) nitrate  → magnesium nitrate + copper

Chemical equation:

Mg(s) + CuNO₃(aq)    →    Mg(NO₃)₂ (aq)  + Cu (s)

Balanced chemical equation:

Mg(s) + 2CuNO₃(aq)    →    Mg(NO₃)₂ (aq)  + 2Cu (s)

The given reaction is single replacement reaction. In this reaction Mg metal react with copper nitrate and form magnesium nitrate and solid copper.

The given reaction completely follow the law of conservation of mass because there are equal number of atoms of each elements are [resent on both side of equation.

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
