Question

1. Dissolve 1 teaspoon of Epsom salts in a half cup of water.

Answer 1

Answer:

1) $MgSO_4 + 2 NH_4OH \longrightarrow (NH_4)_2SO_4 + Mg(OH)_2$

2) Double displacement reaction

Explanation:

1) Balancing the equation:

The reaction: $MgSO_4 + NH_4OH \longrightarrow (NH_4)_2SO_4 + Mg(OH)_2$

In a first look we see that the amonium cations are unbalanced so:

$MgSO_4 + 2 NH_4OH \longrightarrow (NH_4)_2SO_4 + Mg(OH)_2$

Checking element by element we can see that the equation is balanced

2) In this reaction, the amonium discplaces the Mg to form the amonium sulfate. This is a displacement reaction.

Given that it also forms another product ($Mg(OH)_2$) it's categorized as a double displacement reaction.

Answer 2

1. The balanced equation for the reaction between magnesium sulfate and ammonia is MgSO4 + 2NH4OH → (NH4)2SO4 + Mg(OH)2
2. The reaction between magnesium sulfate and ammonia is double displacement.
