Even though carboxylic acid molecules are only about 1% dissociated in water, they are still significantly more acidic than alcohols. Which of the following is the best explanation for the acidity of the carboxyl group? Select the correct answer below. When a carboxylic acid ionizes, the negative charge on the anion is shared by the two oxygen atoms in the carboxyl group. When a carboxylic acid is reduced, the hydrogen on the hydroxyl group is released. When a carboxylic acid ionizes, the negative charge on the anion is stabilized by the carbonyl carbon. When a base neutralizes a carboxylic acid, the metal cation is stabilized by the anion formed by the carbonyl carbon.

(2) The ammeter shown in the circuit is designed to read a max current of 5A. Assume the ammeter equivalent resistance $R_{AM}$ is placed in series with the 20 ? resistor as shown to measure the current $i_o$. Given the ammeter measures $i_o = 1.498$ A. Determine the value of $R_{AM}$ (in ?) if the 50V source produces a current of 2 A.

Can you please give me a theoretical answer for this question as this is java programming question: The question is do you actually agree with the theoretical representation of the results presented to you? How would you go about proving or disproving what you have been told about the order of algorithms in relation to reality? a. Create an unsorted array list with 100 random items in it and then perform a linear search on the array list looking for an item that is present in the list. Count the number of comparisons required to find the item in the list. b. Do the same problem as part a again, but this time look for an item that is not in the list.
