1A) For the reaction: I2(g) + Br2(g)<--->2IBr(g), Kc=8.7E2 at 150 degrees celsius. Suppose that 5.04 moles of each substance is placed in a 2.000L container. Will the number of moles of each substance at equilibrium be higher or lower than 5.04? Explain?
B) If Ka is 1.75E-5 for acetic acid, calculate the pH at one-half the equivalence point and at the equivalence point for a titration of 50ml of 0.100M acetic acid with 0.100M NaOH?
Suppose that the atomic mass unit (amu) had been defined as one-sixth of the average mass of an atom of fluorine instead of one-twelfth of the mass of an atom of carbon-12. What would the average atomic mass of phosphorus be on this new scale

Solid NaF has the so-called NaCl structure. The shortest distance between the centre of a sodium cation and the centre of a fluoride anion is 231.5 pm.
An evacuated (empty) 276 mL glass bulb weighs 129.6375 g. Filled with an unknown gas, the bulb weighs 130.0318 g. Calculate the gas density in g/L.
Depending on temperature, RbCl can exist in either the rock-salt or CsCl structure type. Give the cation and anion coordination number for each structure type.
375.00 mL of a 0.010 M solution of NaCl are condensed down to 167.00 mL. Assuming the solution does not become saturated during this process, what is the final concentration of NaCl
