Question

Decide whether a chemical reaction happens in either of the following situations. If a reaction does happen, write the chemical equation for it. Be sure your chemical equation is balanced and has physical state symbols. situation chemical reaction.

A strip of solid magnesium metal is put into a beaker of 0.042M SnCl3 solution.

Answer 1

Answer:
`3Mg(s)+2SnCl_3(aq)\rightarrow 3MgCl_2(aq)+2Sn(s)`

Step-by-step explanation:

Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

A more reactive element is one which can easily lose or gain electrons as compared to the other element.

As Magnesium is more reactive than tin, it can easily displace tin from its salt solution
`(SnCl_3)` and form magnesium chloride and tin in elemental form.

The balanced chemical equation is:

`3Mg(s)+2SnCl_3(aq)\rightarrow 3MgCl_2(aq)+2Sn(s)`
