The major component of vinegar is acetic acid CH3COOH. Which of the following reactions represents the balanced equation between acetic acid and sodium bicarbonate?
a. CH3COOH(aq) + NaHCO3 a CH3COONa(aq) + CO2(g) + H2O(I)
b. CH3COOH(aq) + 2 NaHCO3(aq) + 3/2 O2(g) a 4 CO2(g) + 3 H2O(I) + 2 Na+(aq)
c. CH3COOH(aq) + NaOH(aq) a CH3COONa(aq) + H2O(aq)
d. 2 CH3COOH(aq) + Na2CO3(aq) a H2CO3(aq) + 2 CH3COONa(aq)
Acetic acid is CH3COOH. Sodium bicarbonate is NaHCO3. What part of the question about balancing do you not understand. An equation is balanced when it has the same number of atoms of each element on each side of the arrow.
