Question

which of the following elements are in the compound: *
magnesium sulfate
mgso₄
oxygen (o), nitrogen (n) and magnesium (mg)
potassium (k), oxygen (o) and carbon (c)
magnesium (mg), sulfur (s) and oxygen (o)

Explanation:

Step1: Analyze the compound formula

The formula of magnesium sulfate is \(MgSO_4\).

Step2: Identify the elements

From \(MgSO_4\), we can see the elements are Mg (magnesium), S (sulfur), and O (oxygen).

Step3: Check the options

• Option A has nitrogen (N) which is not in \(MgSO_4\).
• Option B has potassium (K) and carbon (C) which are not in \(MgSO_4\).
• Option C has Mg, S, and O which match the elements in \(MgSO_4\).

Answer:

C. Magnesium (Mg), Sulfur (S) and Oxygen (O)
