Which of the following compounds is a strong acid?

Which of the following compounds is a strong acid?

Step 1: Understand what a strong acid is. A strong acid is a substance that completely dissociates into its ions in water.
Step 2: Look at the compounds given: H2SO4, H2O, H2O2, and NH3.
Step 3: Identify H2SO4 (sulfuric acid). It is known to completely dissociate in water, making it a strong acid.
Step 4: Check H2O (water). It is neutral, meaning it does not act as an acid or a base.
Step 5: Check H2O2 (hydrogen peroxide). It is a weak oxidizer and does not act as a strong acid.
Step 6: Check NH3 (ammonia). It is a weak base, not an acid.
Step 7: Conclude that H2SO4 is the only strong acid among the options.
