The question asks for the chemical formula of Ammonium Sulfate. Step 1: Identify the ions involved. • The ammonium ion is NH_4^+. • The sulfate ion is SO_4^2-. Step 2: Determine the ratio of ions needed to form a neutral compound. To balance the +1 charge of the ammonium ion and the -2 charge of the sulfate ion, two ammonium ions are required for every one sulfate ion. Step 3: Write the chemical formula. Combining two NH_4^+ ions with one SO_4^2- ion gives the formula (NH_4)_2SO_4. Step 4: Compare with the given options. (A) (NH_3)_2SO_4 - Incorrect, NH_3 is ammonia, not ammonium. (B) NH_3SO_4 - Incorrect. (C) NH_4SO_4 - Incorrect, charges are not balanced. (D) (NH_4)_2SO_4 - Correct. The correct option is (D). (D) (NH_4)_2SO_4 That's 2 down. 3 left today — send the next one.
