Using the data below and Coulomb\'s law, calculate the energy change for this reaction (per formula unit of MgS). Mg + S =Mgs
Choose the answer in which the two atoms are listed in order of increasing ionization energy (smallest ionization energy listed first).
Adipic acid, HOOC(CH2)4COOH, is among the top 50 manufactured chemicals in the United States (nearly 1 million metric tons annually). Its chief use is in the manufacture of nylon. It is a diprotic acid having Ka1=3.9×10?5 and Ka2=3.9×10?6.

Sodium azide (NaN3) is the chemical used in air bags. Sensors detect the initial crash and electrically initiate the explosion of a small charge of this compound
The use of phenols such as tert-butylcatechol as free-radical scavengers is based on the fact that phenolic hydrogens are readily abstracted by radicals
The following molecular equation represents the reaction that occurs when aqueous solutions of silver nitrate and aluminum chloride are combined.
Two readings (initial volume and final volume) are required to deliver a specified volume of titrant. For a delivered volume of 6.25 mL, compute the uncertainty in the volume of titrant delivered.
The ionization constant, Ka, for HOI(aq), hypoiodous acid, is 2.3 × 10-11. What is the pH of a 0.050 molar solution of sodium hypoiodite, which contains the hypoiodite ion?
