Question

which of the following elements are in the compound: *
sulfuric
acid
h₂so₄
helium (he), sulfur (s), oxygen (o)
nitrogen (n), calcium (ca), and potassium (k)
hydrogen (h), sulfur (s), oxygen (o)

Explanation:

Step1: Analyze the compound formula

The formula of sulfuric acid is \(H_{2}SO_{4}\).

Step2: Identify elements from formula

From \(H_{2}SO_{4}\), we can see the elements are Hydrogen (H), Sulfur (S), and Oxygen (O).

Step3: Check each option

• Option A: Helium (He) is not in \(H_{2}SO_{4}\).
• Option B: Nitrogen (N), Calcium (Ca), and Potassium (K) are not in \(H_{2}SO_{4}\).
• Option C: Hydrogen (H), Sulfur (S), Oxygen (O) are all in \(H_{2}SO_{4}\).

Answer:

C. Hydrogen (H), Sulfur (S), Oxygen (O)
