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 two acids, aspirin and citric acid. Baking powder may contain an acid like cream of tartar, calcium acid phosphate, or some other acid. When either of these products is placed in water, the acid and sodium bicarbonate react to produce carbon dioxide gas.
