2 the names and chemical formulas of four substances are shown in the chart. substance formulas name chemical formula carbonic acid h₂co₃ nitric acid hno₃ phosphoric acid h₃po₄ sulfuric acid h₂so₄ which substance listed in the chart is made up of the most atoms? a carbonic acid b nitric acid c phosphoric acid d sulfuric acid a a b b c c d d
Answer
Explanation:
Step1: Count atoms in carbonic acid
For $H_2CO_3$, number of atoms = 2 (H) + 1 (C) + 3 (O) = 6.
Step2: Count atoms in nitric acid
For $HNO_3$, number of atoms = 1 (H) + 1 (N) + 3 (O) = 5.
Step3: Count atoms in phosphoric acid
For $H_3PO_4$, number of atoms = 3 (H) + 1 (P) + 4 (O) = 8.
Step4: Count atoms in sulfuric acid
For $H_2SO_4$, number of atoms = 2 (H) + 1 (S) + 4 (O) = 7.
Answer:
C. Phosphoric acid
