check answer

Explanation:

Step1: Analyze the hydrate formula structure

A hydrate formula has the form \( \text{Compound} \cdot n\text{H}_2\text{O} \), where \( n \) is the number of water molecules. The prefix in the name corresponds to \( n \): mono- (1), di- (2), tri- (3), penta- (5), hexa- (6), hepta- (7).

Step2: Match each formula with the name

• For \( \text{MgSO}_4 \cdot \text{H}_2\text{O} \) ( \( n = 1 \) ), the name is Magnesium sulfate monohydrate.
• For \( \text{MgSO}_4 \cdot 2\text{H}_2\text{O} \) ( \( n = 2 \) ), the name is Magnesium sulfate dihydrate.
• For \( \text{MgSO}_4 \cdot 3\text{H}_2\text{O} \) ( \( n = 3 \) ), the name is Magnesium sulfate trihydrate.
• For \( \text{MgSO}_4 \cdot 5\text{H}_2\text{O} \) ( \( n = 5 \) ), the name is Magnesium sulfate pentahydrate.
• For \( \text{MgSO}_4 \cdot 6\text{H}_2\text{O} \) ( \( n = 6 \) ), the name is Magnesium sulfate hexahydrate.
• For \( \text{MgSO}_4 \cdot 7\text{H}_2\text{O} \) ( \( n = 7 \) ), the name is Magnesium sulfate heptahydrate.

Answer:

• \( \text{MgSO}_4 \cdot \text{H}_2\text{O} \) → Magnesium sulfate monohydrate
• \( \text{MgSO}_4 \cdot 2\text{H}_2\text{O} \) → Magnesium sulfate dihydrate
• \( \text{MgSO}_4 \cdot 3\text{H}_2\text{O} \) → Magnesium sulfate trihydrate
• \( \text{MgSO}_4 \cdot 5\text{H}_2\text{O} \) → Magnesium sulfate pentahydrate
• \( \text{MgSO}_4 \cdot 6\text{H}_2\text{O} \) → Magnesium sulfate hexahydrate
• \( \text{MgSO}_4 \cdot 7\text{H}_2\text{O} \) → Magnesium sulfate heptahydrate
