In an experiment to determine the amount of aspirin in a tablet, one of the bottles of NaOH used was accidentally left open for 24 hours, which lead to it reacting with carbon dioxide. What will be the effect on the calculated amount of aspirin compared to the actual amount in the tablet and the concentration of the NaOH solution? Calculated amount increases since NaOH concentration will be lower than original. Calculated amount increases since NaOH concentration will be higher than original. O Calculated amount decreases since NaOH concentration will be lower than original. O Calculated amount decreases since NaOH concentration will be higher than original.

Which of the following best describes why magnesium hydroxide, found in milk of magnesia, is soluble in acidic solution? O According to Le Chatelier's principle, the acid will react with hydroxide ions in the solution, forming water and thereby decreasing the concentration of hydroxide ions in solution causing more magnesium hydroxide to dissolve. O Magnesium hydroxide does not dissolve in acidic solutions. O According to Le Chatelier's principle, the acid will react with magnesium ions in the solution, forming magnesium hydride and causing more magnesium hydroxide to dissolve. O According to Le Chatelier's principle, the acid will react with water in the solution, forming hydroxide ions and thereby decreasing the concentration of magnesium ions in solution causing more magnesium hydroxide to dissolve. O According to Le Chatelier's principle, the acid will react with hydroxide ions in the solution, forming a precipitate.
How is Q related to Keq? Group of answer choices Q is calculated using the equilibrium expression, but uses the given concentrations and conditions; if the system is at equilibrium, Q = Keq. Q is always larger than Keq. Q = Keq when the equilibrium is shifted toward products. Q = Keq only under standard conditions. Q is the same as Keq and is calculated in the same way.
