You have three molecules of sodium bicarbonate 3NaHCO3. Which statement is true?

The number of oxygen atoms (O) is less than the sum of the sodium (Na), hydrogen (H), and carbon (C) atoms.

The number of carbon atoms (C) is three times greater than the number of oxygen atoms (O).

The number of oxygen atoms (O) is greater than the sum of the sodium (Na), hydrogen (H), and carbon (C) atoms.

The number of sodium atoms (Na) equals the number of hydrogen atoms (H).

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
