Explanation: Both acids and bases produce ions in solution, are electrolytes, and conduct electricity in solution. Although red litmus is an indicator, it does not change color in an acid, acids are proton donors while bases are proton acceptors. Soaps often contain bases, not acids. 74) A person opens a 2-liter bottle of cola at a picnic. If the cap is left off the bottle, the cola will become 'flat' or lose it's carbonation. Which statement below BEST summarizes why the cap must be kept tightly in place if the cola is to remain fresh? The cap prevents the liquid in the cola from A) evaporating. The cap keeps the atmospheric gases and liquid from B) mixing in the bottle. The cap warm air from entering the two-liter C) bottle and raising the temperature of the cola solution. The cap keeps the pressure of the gas in the bottle at a high level D) preventing carbon dioxide from leaving the solution. Explanation: The cap keeps the pressure of the gas in the bottle at a high level preventing carbon dioxide from leaving the By keeping the pressure high, the solubility of carbon dioxide in the solution is increased. solution. 75) Data Analysis Elements Density 2.698 Aluminum g/mL Calcium 1.54 g/mL 7.8738 Iron g/mL 2.3296 Silicon g/mL Sanjay is learning about the elements that make up Earth’s crust.
