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 contains various soluable compounds, such as asperin and citric acid, combined in a tablet form with bicarbonate of soda. The bicarbonate of soda reacts when it i â¦ s in water, giving off carbon dioxide.This action makes the other materials present disolve faster than they otherwise would.ell, if you add water to water, the first water dissolves into the second water. But when that happens, it just makes more water. That shows that water does not dissolve wa â¦ ter. So you can't dissolve water in water.
