Final answer:
Magnesium displaces tin in the SnCl₂ solution, resulting in the production of magnesium chloride in solution and solid tin. This is a metal replacement reaction where no hydrogen gas or precipitate is produced.option 2.
Step-by-step explanation:
When a strip of solid magnesium metal is put into a beaker of 0.062M SnCl₂ solution, a metal replacement reaction occurs. Magnesium, being more reactive than tin, will replace the tin in the solution and the products of this reaction will be magnesium chloride in solution and solid tin metal:
Mg(s) + SnCl₂(aq) → MgCl₂(aq) + Sn(s)
This reaction can be seen as a type of single-replacement reaction, where a more reactive metal displaces a less reactive metal from its compound. In this case, no hydrogen gas is produced, and there is no precipitate since magnesium chloride is soluble in water. So the correct answer to the question is: The magnesium strip dissolves and forms magnesium chloride.
