Will mark ! which of the following is the electron configuration of an electrically neutral alkaline earth metal a. 1s2 2s1 b. 1s2 2s2 2p2 c. 1s2 2s2 2p6 3s1 d. 1s2 2s2 2p6 3s2 3p6 4s2 i feel like the answer is d, but i’m not sure.

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

Can someone me with questions 12 and 13 plz.

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
