Best Answer: From reference 1: A football field (including the two end zones) is 360 feet long and 160 feet wide for a total of 57,600 square feet. When you take away the two 30-foot-long end zones at each end, the field is 48,000 square feet, making an acre about 91% of the field.
Alka-Seltzer is made of aspirin, citric acid, and sodium bicarbonate (NaHCO3). When sodium bicarbonate dissolves in water, it splits up to make sodium (Na+) and bicarbonate (HCO3â) ions. NaHCO3 (Sodium bicarbonate) â Na+(Sodium ion) + HCO3â (Bicarbonate Ion)
Alka Seltzer tablets contain solid sodium bicarbonate and citric acid. When dropped into water, sodium citrate, carbon dioxide, and water are formed: The sodium citrate is a weak base. It neutralizes stomach acid (mainly HCl) by the following reaction: Na 3 C 3 H 5 O 7 (aq) + 3 HCl(aq) H 3 C 3 H 5 O 7 (aq) + 3 NaCl(aq). Author: Fred Senese senese@antoine.frostburg.edu.
