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)
Lava Lamp â Alka Seltzer. Oil and water do not mix. If you try to shake up the bottle, the oil breaks up into small little drops, but the oil does not mix with the water. When you pour the water into the bottle with the oil, the water sinks to the bottom and the oil floats to the top. Oil floats on the surface because water is heavier than oil. Water is more dense than the oil. The Alka-Seltzer tablet reacts with the water to make carbon dioxide gas. These bubbles attach themselves to the colored water and cause them to float to the surface. When the bubbles pop, the color sinks back to the bottom of the bottle.
